Fiberglass isn’t something that you want to have inside your mattress.
If you buy a mattress that contains fiberglass then you are at risk of experiencing skin irritation, allergic reactions, breathing difficulties, and a lot of expense to have the shards professionally removed from your home if the fibers escape from the mattress.
However, finding a mattress that really doesn’t contain fiberglass can be difficult because manufacturers aren’t totally honest when it comes to disclosing such information and may use obscure labeling to hide that the mattress does indeed contain fiberglass.
I have personally tested many mattresses and I can tell you for a FACT that some of the other ‘best mattresses that don’t contain fiberglass’ lists online are WRONG because I have personally bought some of those mattresses, cut open the sidewall, and found fiberglass inside.
That’s why I have put together this list of the best fiberglass-free mattresses where I’ve included videos so that you can see first hand there is NO fiberglass in these mattresses.
So just to be clear, which mattresses don’t contain fiberglass?
The best mattresses that absolutely do not contain fiberglass are the Nolah Natural 11″, DreamCloud Hybrid, and SweetNight Twilight mattresses – as personally verified by myself by cutting open the mattresses and looking inside.
Check out the 8 best fiberglass-free mattresses below.

1: Nolah Natural 11″ Hybrid Natural Latex Foam – Best Overall
The Nolah Natural mattress is the best mattress without fiberglass that I have personally tested because I have cut this mattress open and checked for myself that there is no fiberglass inside this mattress, and the specs mean that this mattress is suitable for all sleeper types.
You can see for yourself that there is no fiberglass in the Nolah Natural mattress by watching my video review above.
Read the summary below to check the mattress suitability for your needs and click the red button to buy this mattress now and save $600.
- Fiberglass free – the fire barrier is made from natural wool rather than harmful fiberglass.
- Hybrid design – 3″ natural latex foam sits over 8″ of individually encased pocket coils.
- Luxury firm – the luxury firm feel means that the mattress has underlying pushback to guard against sinkage but is also adaptive enough to allow for pressure relief on your body.
- Natural Talalay latex – the natural Talalay latex is free from synthetic materials and is much more bouncy and breathable than memory foam, yet is able to provide a high degree of adaptive pressure relief.
- Zoned support – the pocket coils are arranged into 3 zones so that there’s more ‘give’ around the shoulders and knees when compared to the firmer feel around the hip region to keep you in good posture.
- Sensitive sleepers with allergies – the latex foam is natural, the cover is organic cotton, and the mattress is free from synthetic chemicals so there is a very low chance of you experiencing an allergic reaction or the worsening of asthma, eczema, hayfever, or dust mite allergies when sleeping on the Nolah Natural. I experienced no issues with my allergies at all.
- Hot sleepers – the combination of the breathable Talalay latex with its pinhole core design works with the spacious coil core to dissipate heat very effectively and make the Nolah Natural perfect for hot sleepers like me that tend to overheat in memory foam mattresses.
- Front, back, and side sleepers – the arrangement of the zoned coils and the inclusion of the bouncy and responsive latex foam makes the Nolah Natural perfect for front, back, and side sleepers alike. I was personally able to sleep comfortably in all of these positions which is remarkable since I have bad arthritis pain in my shoulders and knees.
- Restless and combination sleepers – if you switch positions often during the night, then the bounce of the coils and latex foam makes the Nolah Natural easy to move around in. I found it very easy to turn over and I didn’t feel like I was getting stuck in the materials at all.
- Both heavy and light weighted sleepers – the Nolah Natural can support up to 350 lbs on each half of the mattress (700 lbs total) thanks to the robust coil core, whilst the adaptive Talalay latex allows lighter weighted sleepers under 150 lbs the ability to sink more deeply into the materials to dissipate pressure away from your joints.
- Skinny sleepers – the latex foam can help to soften abrasion points on your bones and joints if you have a lower body fat percentage.
- Limited edge support – if you weigh more than 230 lbs and sleep closer to the edge of the mattress, then you should go for a mattress with reinforced edges like the DreamCloud for better edge support.
- Good buyer protection – the 120-night sleep trial means that you can test out the mattress risk free and return it if you don’t like it and the lifetime warranty protects you against defects.
2: DreamCloud – Best Mattress With Edge Support
The DreamCloud hybrid mattress is the best fiberglass-free mattress if you are looking for a mattress with a firmer feel and brilliant edge support.
You can watch the video above to see for yourself that the DreamCloud mattress doesn’t contain any fiberglass when I cut open the side-wall of the DreamCloud and show you the materials inside.
The DreamCloud is available in the US and UK – making it a great choice if you’re looking for a fiberglass-free mattress in the UK.
Check out the summary below and click the red button to buy the DreamCloud and save $200 now.
- Hybrid design – memory foam and polyfoam sit over pocket coils to provide pressure relief and support.
- Medium firm – the medium-firm feel means that you can lie on this mattress on your front or back without sinking in too far, whilst the memory foam will provide pressure relief to keep you comfortable on your side. I personally think that the DreamCloud feels a bit firmer than the other medium-firm mattresses I’ve tested – giving it a bias towards front and back sleepers on the heavier side.
- Reinforced edges – the reinforced coils around the edge of the mattress will stop you from sinking too far in when sitting or lying on the edge of the DreamCloud. The DreamCloud has some of the best edge support that I’ve seen out of all the mattresses I’ve tested so far.
- Edge sleepers – the reinforced edges makes the DreamCloud ideal if you hug the edge of the mattress as you sleep.
- Front and back sleepers – the firmer feel makes the DreamCloud better for front and back sleepers that need a touch more pushback to keep you in good posture.
- Heavier weighted sleepers – if you weigh more than 200 lbs then the DreamCloud’s excellent support and robust coils will help to guard against sinkage to keep you well supported.
- Combination sleepers – the bounce of the DreamCloud makes it easy to switch positions and move around in.
- Not as good for sleepers under 130 lbs – the Nolah Natural is the better choice if you are on the light side because it has more ‘give’ and pressure relief.
- Cooling – although this mattress contains memory foam, I personally found it to be very cooling due to the hybrid design.
3: SweetNight Twilight – Cheapest Fiberglass Free Mattress
If the other mattresses on this list are too expensive for you then the cheapest fiberglass-free mattress that I could find is the Twilight hybrid mattress from SweetNight.
Now, just to be clear, I checked with their customer support, and the MEMORY FOAM mattresses from SweetNight DO contain fiberglass – but the hybrid versions do NOT contain fiberglass (which means that you’ll be ok with the Twilight, Island, and Ocean Blue models):
- Side sleepers – the gel infused memory foam combines with the coils to provide a blend of pressure relief and support in the side sleeping position.
- Front and back sleepers – the slightly firmer bias and adaptive coil support core can help to maintain good posture when sleeping on your front or back.
- Edge sleepers – the edge to edge support can help to guard against roll-off and sagging when you sleep closer to the edge of the bed.
- Restless sleepers – the memory foam can help to alleviate the pressure points that can otherwise contribute to frequent waking, whilst the buoyancy of the coils can make it easy to switch positions without getting bogged down in the materials.
- Heavier weighted sleepers – the steel coils can help to support weights in excess of 230 lbs and guard against excessive sinkage.
- Couples – the foam and individually wrapped coils can help to dampen movements so that you can each sleep undisturbed.
- US only – you can only order this mattress in the US.
- CertiPUR-US® certified – to ensure that the mattress is free from toxic chemicals and that VOCs counts are kept to less than 0.5 parts per million to reduce off gassing (smells).
- 10 year warranty – covers you against defects for extra peace of mind.
- 100 day refund policy – get a full refund if you’re not happy with your mattress.
- Super cheap – the Twilight is one of the best mattresses for the money relative to the quality that you’re getting.
4: Noa – Best Fiberglass Free Mattress Outside the US
Trying to find a fiberglass-free mattress outside the US can be difficult because most of the best mattress-in-a-box brands don’t ship outside the US – this means that you’ll likely be forced to buy from Amazon where you are more likely to find cheap memory foam mattresses that contain fiberglass.
The best mattress without fiberglass available outside the US that I’ve personally reviewed is the Noa – you can currently buy it online and have it shipped to the UK, Canada, Australia, or Singapore.
You can’t currently order the Noa in the US – so I would recommend the DreamCloud as a suitable alternative if you live in the US.
- Hybrid design – contains springs, gel memory foam, and polyfoam for a blend of support and pressure relief.
- Medium-firm – a firmer feel that will suit front and back sleepers with the foam providing pressure relief for side sleepers.
- Front and back sleepers – the firmer feel and support favors front and back sleepers that need more support.
- Combination sleepers – the bounce of the springs and latex makes the Noa ideal for combination sleepers that need to switch positions often.
- Edge sleepers – the support extends all the way up to the edge of the mattress so that you won’t sink in as you hug the edge of the bed.
- Warmer sleepers – I found the Noa to be very breathable and cooling; which is ideal if you are a warmer sleeper like me.
- Sleepers with back pain – if you have back pain that gets worse when lying on a mattress that’s too soft then the firmer feel of the Noa can help to stop this.
- Firmer for lighter weighted sleepers – lighted weighted side sleepers in particular may prefer the softer feel provided by the Nolah Natural.
- 100 night sleep trial – try the Noa risk free for 100 nights and get your money back if you don’t like it.
5: Avenco – Best for Heavier Weighted Sleepers
The best fiberglass-free mattress for heavier weighted sleepers is the Avenco Zone Hybrid mattress because it has a firmer feel and zoned support to provide more pushback that can help to guard against excessive sinkage and keep you in good posture.
Watch the video above to see inside the Avenco mattress and to check for fiberglass yourself.
- Hybrid design – gel memory foam, polyfoam, and pocket coils provide firm support with some pressure relief.
- Firm feel – the Avenco has a firm feel that will benefit front and back sleepers due to the increased pushback that can support your hips.
- Zoned support – the Avenco comes with a 5 zoned support core to provide more ‘give’ around the shoulders and knees, whilst the head, hip, and foot regions are firmer to combine to keep you in good posture.
- Heavier weighted sleepers – the firmer feel and robust zoned support means that the Avenco can handle weights greater than 300 kg whilst keeping you in good posture.
- Front and back sleepers – front and back sleepers (especially on the heavier side) will be able to enjoy good posture thanks to the firm feel and zoned support.
- Combination sleepers – I found the Avenco to be a bouncy and responsive mattress that allowed me to switch positions easily.
- Will feel firm to lighter weighted sleepers – if you weigh less than 150 lbs then the Avenco may feel a bit too firm; try the Nolah Natural for more pressure relief.
- 100 night sleep trial – try the Avenco for a 100 nights and get a full refund if you don’t like it.
6: Naturepedic EOS Classic – Ideal for Couples
Naturepedic do not use flame retardant chemicals in their mattresses.
Instead, they meet flammability standards by using a combination of organic wool, organic cotton fabric, organic cotton batting, and plant-based non-GMO PLA batting rather than using a flame barrier soaked in chemicals.
This means that there’s no fiberglass or other potentially harmful or undesirable chemicals found in Naturepedic’s mattresses such as antimony, modacrylic, respirable crystalline silica, boric acid, or rayon.
Furthermore, Naturepedic’s mattresses have been certified by MADE SAFE® – which means that the mattresses do not contain harmful ingredients or release vapors, gases, or by-products that could harm human health (view certificate).
More specifically, the MADE SAFE® certification means that the mattress has been screened for carcinogens, fire retardants, heavy metals, neurotoxins, harmful VOCs, and more.
Moreover, the EOS Classic mattress has some of the most highly regarded certifications such as the GOTS, GOLS, and GreenGuard certifications to ensure that you’re sleeping on a mattress that’s non-toxic and healthy for you.
Beyond this, the EOS Classic Organic Mattress can be customised to suit your sleeping style and preferences.
This means that the EOS is perfect for single sleepers, but also for couples especially – since you can choose to have different firmnesses on each half of the mattress if you and your partner have different preferences.
Click the button below to check the price of the EOS and buy it now directly from Naturepedic – or see below for more details.
- Hybrid spring-latex – 3″ GOLS certified organic latex comfort layer with 8″ encased coil support core and an organic cotton and wool quilt with PLA padding for added moisture wicking to keep you cool and dry.
- 12 inch profile – deeper profile for greater capacity for pressure relief and support.
- Split firmness options – choose from a uniform firmness or two different firmnesses in the queen, king, and Cal. king sizes.
- Side sleepers – the plush firmness option may be better for side sleepers under 230 lbs for added pressure relief on the hips and shoulders, whilst heavier weighted side sleepers may prefer a medium.
- Front sleepers – if you sleep on your front then the firmer options may suit you better to help keep your hips properly aligned to guard against back pain.
- Back sleepers – the medium level of firmness may suit you the best if you’re a back sleeper in the 130-230 lbs range, whilst firmer options might be preferable if you weigh more, and the plusher or cushioned-firm if you weigh less.
- Combination sleepers – the combination of responsive latex and support coils gives this mattress enough buoyancy to allow you to switch positions without getting bogged down in the materials – especially if you go for a firmer feel to increase the surface tension of the mattress.
- Edge sleepers – the reinforced edge support means that you can sleep close to the edge of the bed without risking roll-off.
- Skinny sleepers – the plush level of firmness allows for greater pressure relief and material sinkage to take the pressure away from your bones and joints.
- Couples – in addition to the split firmness option, the individually encased coils can help to reduce motion isolation so that you don’t wake each other up, whilst the reinforced edges allow you to make full use of the mattress area.
- Warmer sleepers – the porous latex and the coil core combine to allow for excellent airflow to help regulate your temperature and keep you cool.
- Sweaty sleepers – the PLA layer near the cover is made from non-GMO sugarcane that wicks away moisture to help keep you dry.
- Allergy sufferers and sensitive sleepers – the lack of toxic chemicals and potentially anti-fungal qualities of the organic latex makes the mattress less likely to trigger asthma symptoms, airway irritation, and skin irritation.
- Higher cost – with this being an organic mattress, you might want to go for the 0% APR financing option to help make this mattress more affordable for you.
- Ships to Canada as well as the USA – making it one of the best mattresses that you can buy for Canadians.
- Swap the layers yourself – you can unzip this mattress (with no fiberglass to worry about) and switch the layers of the mattress around yourself to adjust the comfort preferences for years to come.
- Multiple organic and safety certifications – including GOTS, GOLS, GreenGuard, and MADE SAFE®.

- Pay on 0% APR – financing options available to make your mattress more affordable (click the button below for more details).
7: Natural Bliss – Best Vegan Mattress
If you need a mattress that doesn’t contain fiberglass and is also vegan then the Natural Bliss from Plush Beds is likely going to be the best mattress for you.
Because this mattress doesn’t contain wool or any other products derived from animals.
Instead, the patented Eco Fire Barrier is made from natural plant fibers, whilst the rest of this all-latex layered mattress consists of natural latex and a GOTS certified organic cotton cover to minimize toxins even more.
This mattress is available in soft, medium, medium-firm, and extra-firm – making it suitable for just about every sleeping position as well as for couples too.
- Side sleepers – the soft level of firmness is likely the best level of firmness to provide pressure relief on your hips and shoulders.
- Front and back sleepers – the medium and firmer firmnesses are likely going to be better if you sleep on your front or back to help maintain proper hip alignment and posture.
- Couples – the all-foam design can help to absorb motion transfer better than a spring mattress might so that you don’t disturb each other as you move around.
- Latex allergies – if you have an allergy to natural latex then this might not be the mattress for you because I wasn’t able to find out if this mattress has been stripped of the problematic latex proteins (unlike the Beausommet which has the latex proteins removed).
- Massive range of organic and eco-friendly certifications – including GOTS, USDA, GreenGuard Gold, Oeko-Tex Standard 100, eco-INSTITUT, and Forest Stewartship Council.
- Toxin free – no mercury, lead, heavy metals, CFCs, chloroform, cyanide, or PBDE flame retardants.

Fiberglass Free Mattress Buying Guide
So what is fiberglass and why is it found in some mattresses?
Fiberglass is a type of reinforced plastic that’s made from a range of natural minerals and manufactured chemicals (like silica sand, soda ash, limestone, alumina, borax, and feldspar ) and is used by some manufacturers in their mattresses as part of their fire barrier in order to meet flammability standards.
However, in the case of mattresses, rather than taking the form of an obvious solid sheet of plastic, the fiberglass is integrated more subtly.
More specifically, the fiberglass is typically infused or woven into the inner mattress cover – hidden from view – where most people will never realise that they are sleeping on a type of material that in certain forms can cause eye redness, inflammation of the nose and throat, and aggravation of pre-existing conditions like asthma and bronchitis .
Most people only become aware of the fiberglass in their mattress when they innocently unzip the cover for washing purposes – or a hole develops in the cover.
At which point, the room is filled with tiny shards of fiberglass that contaminate the surrounding bedding, furniture, and carpets – even working their way into the air conditioning where these glitter-like particles can spread through the entire house.
Whilst manufacturers often state on the label of the mattress not to remove the cover, many users don’t realise the potential severity of doing so in a mattress that contains fiberglass.
Because as the video below explains in more detail, whilst the Consumer Products Safety Commission sated that they are not aware of any health risks associated with the type of fiberglass used in mattresses (which is apparently different to the fiberglass used in insulation), several families report experiencing a reaction to the fiberglass that contaminated their home as a result of removing the cover of a fiberglass containing mattress.
At 3:05, you can see how one family actually had to move out of their home due to the impact the fiberglass had on their children’s health, whilst another victim states clearly that ‘his face is burning’ as a result of coming into contact with the fiberglass particles having removed the mattress cover:
1: Learn How to Avoid Mattresses With Fiberglass
The mattress brand that seems to come up over and over again in these fiberglass horror stories is Zinus.
However, there are many more brands that also use fiberglass in their mattress covers.
The table that I’ve included further down the page lists some of the brands that are known or highly likely to contain fiberglass.
However, this table is non-exhaustive and there are some shady tricks that mattress manufacturers pull to try and avoid saying explicitly that their mattresses contain fiberglass.
So here’s a list of the 6 steps that you should take to find out if a mattress has fiberglass in it.
1.1: Learn the Alternative Terms
Here’s some of the terms that if you see them mentioned on the label/law tag or in the product description means the same thing as fiberglass:
- Glass wool.
- Glass fiber.
- GFK (German for ‘Glasfaserverstärkter Kunststoff’).
1.2: Be Aware of Other Harmful Substances
Depending on the type of mattress, there are many other chemicals that could potentially be present in varying amounts that you’ll want to avoid.
Some of the most notable ones include:
- Modacrylic – a controversial flame retardant that some say may cause skin irritation  and others say could be a carcinogen .
- Antimony – a toxic heavy metal often used as a flame retardant in the fire barriers of some mattresses which has been shown to irritate the eyes, skin, and lungs .
- Formaldehyde – sometimes found in the glues of cheap memory foam mattresses and is thought to be carcinogenic .
One component found in the fire barriers of some mattresses that causes confusion is silica.
Because whilst inhaling crystalline silica can lead to fatal diseases like silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD) , the version of silica found in mattresses is amorphous silica which is widely regarded as non-carcinogenic .
However, a report from the CDC sates that even though amorphous silica is considered to be of ‘low toxicity’, inhalation of amorphous silica can irritate the eyes and may be harmful to the body when exposure is prolonged .
And critically, the same report says that ‘pure amorphous silica is rarely found’ and ‘usually contains some amount of crystalline silica’.
The bottom line is that whilst discovering that your mattress contains silica (usually in the inner cover as a fire barrier) doesn’t automatically denote toxicity – it could be a cause for concern depending on the manufacturing process.
1.3: Check the Label, Product Description, and Reviews
So how do you actually go about finding out if your mattress contains fiberglass or not?
If you already have the mattress or are looking at it in the store then you should look at the law tag.
Here, it should state if the mattress contains fiberglass and the percentage amount (‘glass fiber’ and ‘glass wool’ are the same as fiberglass).
The label may also say if the mattress contains modacrylic or silica.
For example, going back to the video I posted earlier, you can see that this law tag sates that the mattress in question contains 62% fiberglass, 30% modacrylic fiber, and 8% cotton:
Another ‘clue’ that the mattress contains fiberglass is when the tag or FAQ page of a mattress manufacturer says that ‘the cover must not be removed’.
But what if you can’t see the law tag?
Then you can reach out to the manufacturer or retailer and ask them if their mattress contains fiberglass or not.
If they try to fob you off with a copy and paste answer saying that ‘all mattresses are designed to meet flammability standards and blah, blah, blah’ then you need to keep pushing.
(I got this response a lot when I was researching for mattresses that don’t contain fiberglass).
Ask them specifically about the fiberglass – if they continue to avoid giving a direct answer then move on and don’t buy from them.
Alternatively, you can scour the FAQ pages, product description, and customer reviews for mention of fiberglass.
1.4: Check the Components of the Fire Barrier
Fiberglass is used as part of the fire barrier so if the customer service is being evasive you can ask them what their fire barrier is made out of.
If you go for an organic mattress then the fire barrier is often made out of wool and is unlikely to contain fiberglass.
1.5: Look For Quality Certifications
Whilst certifications alone are not enough to conclude that the mattress doesn’t contain fiberglass, going for an organic mattress is a good way to minimise the chance of encountering fiberglass.
Also, going for an organic mattress can also help to lessen the likelihood of sleeping on a mattress that contains toxic chemicals that won’t be disclosed on the law tag like formaldehyde.
However, trying to find a truly organic mattress is another headache in itself because there’s no clear way to check that a mattress is certified as organic and that the manufacturer isn’t trying to use ‘green-washing’ claims to mislead you.
Instead, you’ll want to look for a mattress that has some or all of the following certifications:
- USDA Organic – can indicate that the mattress contains 95% organic materials.
- GOLS (Global Organic Latex Standard) – certifies that the latex product contains at least 95% organic material.
- GOTS (Global Organic Textile Standard) – certifies that the product contains at least 70% organic fibers.
Outside of these organic certifications, you should look for the following certifications to confirm that toxic chemicals like formaldehyde are absent, and that VOC (volatile organic compound) emissions have been minimised to an acceptable standard.
- OEKO-TEX Standard 100 – this certification means that the entire product has been labelled as ‘harmless in human ecological terms’.
- CertiPUR-US – this certification means that the poly-foams used in the mattress do not contain certain harmful substances like formaldehyde and has minimal VOCs.
- Eco-Institut – this means that the mattress has been evaluated and labelled as having low-emissions and low-pollutants.
- GREENGUARD and GREENGUARD Gold – these certifications mean that the mattress has been tested and has met strict guidelines for chemical emissions.
1.6: Look for the Common Red Flags
The points below are not a definite indication that your mattress will contain fiberglass, but they are warning signs that are commonly associated with mattresses that contain fiberglass and are more likely to have toxic chemicals in them.
Many of these red flags can occur concurrently.
- Made in China – mattresses that are made in China are known for having fiberglass in them although this isn’t a guarantee.
- Made out of poly-foam/memory foam – mattresses that contain or are made exclusively from cheap poly-foams are the most likely to contain toxic chemicals and fiberglass.
- Costs less than $600 – budget mattresses (often found on popular online retail sites) may be packed with cheap fillers, toxic chemicals, and could contain fiberglass.
- Is a bed-in-a-box – whilst there are many high quality bed in a box mattresses, the rise of the direct to consumer business model means that there are lots of online only mattresses companies that compress their mattresses into a box and cut corners elsewhere to keep costs down – which may also include using fiberglass.
Which Mattresses Contain Fibreglass?
Trying to find a mattress that doesn’t contain fiberglass on your own is a lot of hard work.
So if you’ve got your eye on a particular mattress brand but you’re worried about it containing fiberglass then check out the table below.
Where I went ahead and asked the manufacturer/customer service of several mattress brands if their mattresses contain fiberglass and combined this with the anecdotal reports from several mattresses users.
In some cases, my deeper research yielded results that went against the grain of the other claims out there.
For example, I discovered that Nectar’s mattresses DO contain fiberglass (as confirmed by customer support) – which is contrary to the other findings:
Where anecdotal reports conflicted with the information derived from customer support – or my findings were based exclusively on customer reports – I have used more cautious language in the table below.
|Brand||Contains Fiberglass?||Source of Claims|
|Best Price Mattress||Probably||Customer reviews|
|Dreamfoam Bedding||Unlikely||Customer support|
|Layla||Yes (spun fiber not exposed)||Customer support|
|Idle Sleep||No (Idle Latex)||Customer support|
|Nectar||Yes (layered – not woven)||Customer support|
|Nolah||No (Nolah Natural)||Customer support|
|Puffy Lux Hybrid||Yes (but deeply embedded)||Customer support|
|Purple||Yes (but deeply embedded)||Manufacturer’s site|
|Sweetnight||Some (memory foam beds)||Customer support|
|Tuft and Needle||Unlikely||Customer support|
|Zinus||Yes (all)||Manufacturer’s label|
2: Choose the Right Level of Firmness
Even if you’ve found a mattress that’s fiberglass free, it’s not going to be much use to you if it’s uncomfortable for you.
Comfort is highly subjective and depends on how your preferred sleeping position, body weight, and body shape interacts with the materials and construction of the mattress – as well as the ‘firmness’ of the mattress.
Firmness is something that you often have control over – you can opt for soft, medium, firm, and variations in between like medium-soft and medium-firm.
In rarer cases, you may be able to order your mattress in extra-soft or extra-firm.
Here’s a summary that will help you find the best type of mattress firmness for your sleeping style.
- Soft – softer mattresses are typically better for side sleepers because they allow your shoulders and hips to sink further into the mattress to remove pressure on these areas. If you weigh more than 230 lbs then you may prefer a medium-soft or even a medium because your greater body weight will naturally cause deeper sinkage. if you weigh less than 150 lbs then a soft mattress might be better for you regardless of the position so that you can sink more into the materials and remove the compression forces on your joints.
- Medium – most front and back sleepers in the 130-230 lbs range will be comfortable in a medium firmness mattress; as will some side sleepers along with combination sleepers that tend to shift positions often during the night.
- Firm – firm mattresses are typically preferred by front sleepers who need more hip support to guard against back pain and heavier sleepers over 230 lbs that want to sink into the mattress less.
3: Check the Level of Support
Whilst mattress firmness is variable – support is non-negotiable.
That is, a mattress either supports your spine and joints properly or it doesn’t.
I would recommend going for a mattress that’s no thinner than 8 inches, with a preference for 10 and 12 inch mattresses for sleepers over 230 lbs to provide the sufficient capacity for material compression and support.
Whilst firmness is primarily influenced by the upper comfort layers, the support is dictated by the lower support core.
The best types of support cores are typically those with individually wrapped coils because they adjust to your body shape and reduce motion transfer better than mattresses with a fused spring core typically can.
Mattresses with a Dunlop latex core are also able to provide very good support, as are many high quality memory foam mattresses that use a denser poly-foam support core.
The worst mattresses for providing good support are typically cheap, low-density poly-foam mattresses that are 8 inches thick or thinner (and are also likely to contain fiberglass if they are made in China).
Support is critical if you’re a heavier-weighted sleeper over 230 lbs – look for a spring or hybrid bed with a high coil count (400-1000+ for a queen) and that uses individually wrapped coils, or an all-latex mattress that has a high density Dunlop latex support core.
4: Finalise Your Secondary Preferences
Beyond the firmness and support, you’ll want to take into consideration the following secondary preferences to ensure the maximum amount of comfort.
- Sleeping cool – if you’re a warmer sleeper then spring, hybrid, and latex mattresses are your best option because they have superior ventilation when compared to all-foam mattresses. And whilst many modern memory foam mattresses are infused with cooling gel, gel beads, and have corrugated foams, memory foam is typically known for increasing body heat and are best avoided if you are a hot sleeper.
- Allergy control – if you have respiratory allergies, asthma, or sensitive skin then in addition to avoiding fiberglass you’ll want to look for a mattress that has a hypoallergenic cover to reduce the chance of a reaction and to inhibit dust mite penetration. If you have a wool allergy then go for a vegan certified mattress, whilst those with allergies to natural latex should contact the manufacturer to ensure that the offending proteins have been removed from the latex.
- Edge support – if you’re the type of front sleeper that hugs the edge of the bed or you sleep as a couple that likes to spread out, then you’ll need a mattress with good edge support. Many hybrid and spring beds have good edge support on their own, but you should look for firmer coils around the perimeter; whilst all-foam mattresses will usually require higher density foam along the edges to guard against excessive compression and roll-off.
- Adjustments for couples – if you sleep as a couple then you’ll need a quiet mattress that doesn’t conduct movement easily. All-foam and all-latex mattresses are typically the best at doing this, whilst spring and hybrid beds with individually wrapped coils are typically superior to fused coil cores when it comes to stopping your bed partner from waking you up as they get into bed and shuffle around. If you each require different firmnesses, then going for a split firmness (as per the Naturepedic model listed above) can work better than a mattress with a single firmness.
5: Protect Your Money
Now that you’ve got all of the core criteria by which you can potentially identify your ideal mattress, the final step is to protect yourself from ending up out of pocket.
Here’s what you need to consider.
- A minimum sleep trial of 30 days – even with the help of guides like this, it’s still possible that you could end up with a mattress that’s not comfy. So you should look for a mattress that offers a minimum of a 30 day sleep trial – since it can take up to a month or more for your mattress to adjust to your body type and dominant sleeping position. Look for free shipping and returns so that you’re not left out of pocket if you have to return your mattress.
- 10 year non-prorated warranty – most mattresses last around 5-7 years. But you’ll want to cover yourself with a warranty that’s either entirely non-prorated or has graded non-prorated coverage to ensure that you’re not left shelling out excessively if you end up with a defective mattress.
- Financing – if you want to avoid fiberglass then the best step that you can take is going for an organic mattress. However, these types of mattresses can be expensive – so look for 0% APR financing options to increase affordability.
- Ordering online vs in store – you can save a lot of money by shopping online and a generous sleep trial is typically a better safeguard against discomfort than simply lying on the mattress in the store for 5 minutes (which is too short a time frame to accurately gauge comfort levels).
Here are the answers to some of the most common questions related to fiberglass and mattresses.
What Should I Do if Fiberglass is Released Into the Room?
If you’ve completely removed your mattress cover or fiberglass is escaping through a hole then ideally, you should encase the mattress in plastic wrapping to prevent further release and then remove the mattress from your house. Completely removing the escaped fiberglass particles from your house can be difficult and may require the help of a professional cleaning company.
How Do You Clean a Mattress That Contains Fiberglass?
If you’ve looked at the law tag on your mattress only to discover that it contains fiberglass, then you absolutely must NOT remove the cover. In which case you should spot clean your mattress cover. Better yet, purchase a mattress protector to make cleaning easier and limit the chance of the cover tearing and releasing fiberglass particles.
