The Puffy Lux

It’s important that your new mattress comes with a good warranty.

However, mattress warranties can be confusing and difficult to understand.

Because whilst a longer warranty can offer you protection against defects and manufacturing flaws for a greater period of time, there are several sub-clauses that can undermine the value and worth of the warranty.

For example, some warranties that last a seemingly impressive 20 years or more are only really good for the first 10 years because after this point, prorated coverage usually kicks in and often you’ll have to pay 50% of the costs in year 11, plus an extra 5% for each year thereafter until the warranty expires.

Then there’s the hidden costs associated with return shipping and inspection fees, plus you should remember that most mattresses will need replacing before the 10 year mark due to normal wear and tear (not covered under warranty) – so paying extra for a warranty that goes beyond this point often isn’t really worth it.

That’s quite a lot to figure out.

So to help you out, I’ve gone ahead and done the excruciating research (I read through 44 individual mattress warranties in full… zzzz) and came up with this list of the top 6 mattresses with the best lifetime warranties.

You can check them out below, or jump into the buying guide in the second half of this article that shows you how to find a mattress with a good warranty on your own.

The 6 Best Mattresses With Forever Warranties

The Puffy Lux is my number 1 choice for the best mattress with a lifetime warranty because not only are the terms of the warranty very fair – the mattress is also well suited to a wide range of sleeping styles.

But if you have more specific needs such as requiring a mattress to help with your back pain or regulate your temperature more effectively, then you might prefer some of the other mattresses on this list.

I’ve also included some limited time discounts to help you save some money too.

Click the red buttons under each mattress review below to take advantage of these offers before they expire.

1: Puffy Lux – Best Overall

The Puffy Lux
The Puffy Lux (Puffy.com)

I have picked the Puffy Lux as the best mattress with a lifetime warranty for several reasons.

The first being that the warranty is very simple yet comprehensive – where for the entire lifespan of the Puffy Lux where you are the owner, you are entitled to free repairs or a free replacement in the event of a defect.

Covered defects include indentations and sagging greater than 1.5″, manufacturing flaws with the cover zipper, and physical flaws such as torn fabric or a stitch unravelling – all in the context of proper use.

The second reason why I have chosen the Puffy Lux as the top mattress on this list to buy is that its features make it suitable for just about every sleeping style and position.

More specifically, the Puffy Lux is ideal for side sleepers (the most popular sleeping position) because the memory foam in the upper comfort layer removes the pressure on your shoulders and hips for deeper comfort, whilst the higher density support core provides the support that front and back sleepers need to remain comfortable.

Furthermore, the Puffy Lux is ideal for couples because the all-foam design means that movements are absorbed so that you don’t wake each other up as you move around during the night.

However, if you weigh more than 230 lbs, prefer a bouncier feel, or simply need more support, you can opt for the Puffy Lux Hybrid version for the same price (which also has a lifetime warranty too).

And finally, in addition to the lifetime warranty, you’re also covered by a 101 night sleep trial so that you can return the mattress free of charge for a full refund if you’re not totally comfortable.

If you click the button below, you can get $300 OFF the Puffy Lux for a limited time.

Recommended For

  • Side sleepers – the pressure relieving qualities of the foam makes the Puffy Lux ideal for side sleepers because it can remove pressure on your hips and shoulders better than a regular spring mattress can.
  • Front sleepers – the higher density support foam and medium level of firmness should be sufficient to keep your hips in proper alignment if you weigh less than 230 lbs, and you can go for the hybrid alternative if you weigh more than this or need more support.
  • Back sleepers – the contouring properties of the foam means that the Puffy Lux could support your spine more effectively than a regular spring mattress might be able to for more adaptive comfort.
  • Lighter weighted sleepers – the deeper cushioning of the foam allows sleepers under 150 lbs to sink more deeply into the materials to allow for more dissipation of pressure from your joints (which typically doesn’t happen when you lie on a firmer mattress with a lower body weight).
  • Skinny sleepers – if you have a low body fat percentage then the pressure points that you normally feel in a spring mattress should melt away in the Puffy Lux thanks to the adaptive foam.
  • Couples – with no springs and an all-foam design, movements are soaked up by the Puffy Lux to help you and your partner avoid waking each other up as you move around during the night.
  • Controlling allergies – the hypoallergenic cover can help to inhibit dust mite penetration and limit allergies and airway irritation.

Considerations

  • The hybrid alternative – you might want to opt for the hybrid version of the Puffy Lux if you are a combination or restless sleeper that wants a bouncier mattress to make switching positions easier, or if you’re a front sleeper and/or heavier weighted sleeper over 230 lbs that wants more support and buoyancy to stop you from sinking too far into the mattress.

Other Benefits

  • Fiberglass free – the Puffy Lux is a fiberglass free mattress which means that you don’t have to worry about your health being affected or your home ruined by this sneaky substance that lies beneath the cover of many other types of memory foam mattresses on the market.
  • 101 night sleep trial – goes beyond the warranty to ensure that you can return the mattress for reasons such as comfort preferences.
  • Works with many frames – the Puffy Lux can be used with box springs, flat frames, slatted bases, and adjustable frames.
  • Removable cover – because there’s no fiberglass to worry about, you can remove the zip-off cover and put it in the washing machine or quickly wipe up spills through the stain resistant design.
  • Non-toxic – the foams are CertiPUR-US® certified to ensure that there’s no toxic chemicals like mercury, lead, or formaldehyde [1], whilst the cover is OEKO-TEX® Standard 100 Certified to ensure that odor causing VOCs are limited to an acceptable amount [2].
  • Get $300 OFF – if you click the button below, you can save $300 on your new Puffy Lux mattress (be quick – this offer is time sensitive and will disappear soon).

2: Awara – Best Cooling Mattress (With 1 Year Sleep Trial)

The Awara Mattress Layers.
The Awara Mattress Layers (AwaraSleep.com)

If you’re looking for a cooling mattress with a lifetime warranty then I highly recommend having a look at the Awara Organic Luxury Hybrid Mattress.

Because this 13″ mattress doesn’t contain any heat-trapping memory foam, and instead comes with 4″ of naturally breathable Dunlop latex that sits over 9″ of individually wrapped pocket coils to dissipate heat and help regulate your temperature.

And the 365 night sleep trial means that you can try this mattress out for a full year – through all the seasons – to ensure that you’re comfortable in a range of temperatures.

Awara’s ‘forever’ lifetime warranty means that for the first 10 years of ownership, Awara will replace your mattress with a brand new one at no charge if a defect is confirmed.

After the 10 year mark, Awara will repair, re-cover, or replace your mattress and waive all transportation changes if a manufacturing defect or material failure is confirmed to exist.

Beyond its cooling properties, the lifetime warranty, and 1 year sleep trial, I have included the Awara mattress in this list because the medium-firm feel makes it suitable for nearly all sleeping positions and styles.

More details below.

Recommended For

  • Warm sleepers – the Awara is one of the best cooling mattresses that you can buy thanks to its aerated design, lack of polyfoams, and breathable organic materials that work together to dissipate heat and keep you cool.
  • Side sleepers – the latex foam and adaptive coils can allow you to sink into the materials more than you might expect to make this mattress comfortable for side sleeping.
  • Front sleepers – the coils and slightly firmer bias can help to keep your hips well supported if you sleep on your stomach.
  • Back sleepers – the firmer feel and latex foam combine to support your spine as you sleep on your back.
  • Combo sleepers – if you switch positions often during the night then the bounce of the coils and the responsive feel of the Dunlop latex is ideal for switching positions smoothly without the drag and sinkage that’s associated will all-foam memory foam mattresses.
  • Heavier weighted sleepers – the latex and the coils are ideally positioned to support weights greater than 230 lbs without sinking in like an all-foam mattress might do under heavier loads.
  • Sensitive sleepers – the New Zealand wool, natural latex, breathable cotton, and lack of synthetic foams likely makes the Awara an ideal choice for those with respiratory allergies, asthma, or any other condition that’s aggravated by exposure to dust mites, synthetic chemicals, or other types of allergens found more readily in regular spring or polyfoam mattresses.

Considerations

  • Lighter weighted side sleepers – if you’re a side sleeper and weigh less than 130 lbs then you may find the Awara to be a touch on the firm side; in which case the Puffy Lux should be a good alternative.

Other Benefits

  • 0% APR – pay with Affirm to spread your payments out and increase affordability at no extra cost to you.
  • Save $300 – if you click the button below now, you can get $300 OFF the purchase of your new Awara mattress (this offer is time sensitive so grab it now before it’s gone).

3: Idle Plush – Longest Sleep Trial (1.5 Years)

The Idle Plush Mattress.
The Idle Plush Mattress (IdleSleep.com)

If in addition to a lifetime warranty, you’re looking for a mattress that has a lengthy sleep trial to ensure that you’re completely comfortable and happy with your mattresses then it doesn’t get any better than the Idle Plush mattress from Idle Sleep.

Because not only does this mattress come with a warranty that covers body impressions starting at 0.5 inches (the lowest and best in the industry that I’ve found), the 18 month sleep trial currently stands unrivalled.

And Idle Sleep will repair or replace your mattress if a defect is confirmed at no extra cost to you for the parts.

Beyond the extensive customer protection that buying through Idle Sleep affords, I’ve chosen the Idle Plush model because it has an all-foam design with a medium-soft feel that makes it suitable for a wide range of sleeping positions – especially side sleepers.

More details below.

Recommended For

  • Side sleepers – the 2″ of custom blended gel infused buoyancy foam combines with the 3″ of proprietary Idle Memory Foam to provide exceptional pressure relief for individualised comfort on your hips and shoulders.
  • Back sleepers – the adaptive foam and high density support foam can help to cradle your spine and joints in the back sleeping position.
  • Front sleepers – the high density foam and buoyancy of the foam in the upper comfort layers can help to keep you supported in the front sleeping position.
  • Combo sleepers – although this is a foam mattress, the added buoyancy of the foam in the upper comfort layers can help to make switching from one position to another easier when compared to other types of all-foam mattresses.
  • Lighter weighted sleepers – the pressure relief and sinkage makes the Idle Plush ideal for sleepers under 150 lbs that require deeper material compression.
  • Skinny sleepers – the adaptive foam can help to soothe the pressure points on the more angular areas of your body.
  • Couples – the all-foam structure can help to dampen both vertical and cross mattress movement to help you both sleep undisturbed.

Considerations

  • Heavier weights – if you weigh more than 230 lbs and/or are a front sleeper then you might need a firmer mattress with more support; in which case the Idle Hybrid in medium or luxury firm is probably a better option for you.

Other Benefits

  • Non-toxic foams – the CertiPUR-US®️ certifications means that the foams are free from certain harmful chemicals like PBDE’s mercury, and formaldehyde.
  • 0% APR – spread out your payments for up to 60 months with 0% APR to increase affordability.
  • Save 20% – if you click the button below, you can get 20% OFF the Idle Plush for a limited time only.

4: Level Sleep – Best For Back Pain

The Level Sleep Mattress
The Level Sleep Mattress (LevelSleep.com)

If you’re looking for a mattress with a lifetime warranty that’s specifically targeted at helping to combat back pain then the Level Sleep mattress could be ideal for you.

Because in addition to a ‘forever’ warranty where you can have a defective mattress replaced with a new one in the first 10 years at no extra charge, the Level Sleep mattress uses different foam firmnesses along the length of the mattress for a more customised sleeping experience.

More specifically, the foam around the lower back region is firmer to support your spine, whilst the foam that sits beneath your shoulders is softer to absorb more pressure, and the foam that supports your hips has a medium level of firmness.

This zoned support system helps to keep your spine in optimal alignment to combat back pain and is recommended by several chiropractors.

There’s also a 1 year trial so that you can make sure that you’re happy with the mattress.

If you’d like to know more about buying a mattress specifically for back pain then check out my complete list of the best beds and mattresses for back pain here.

Recommended For

  • Back pain – the zoned support system provides a more customised sleeping surface that may help to reduce pressure and promote better posture that could help to alleviate back pain.
  • All sleeping positions – the varying firmnesses means that this mattress could be comfortable for front, back, and side sleepers across a range of weights.

Considerations

  • Consult your doctor – even though this mattress is endorsed by several chiropractors, I always recommend talking to your doctor before buying a sleeping product based on your individual health needs.

Other Benefits

  • Works with all frames – including divan base, box spring, traditional, platform, adjustable frames, and the floor.
  • Backed by science – the clinical trials mentioned on the sales page explain how participants reported less fatigue and better satisfaction with their sleep on the Level Sleep mattress (click the button below to learn more).

5: Layla Hybrid – Best Double Sided Mattress

The Layla Hybrid Mattress.
The Layla Hybrid Mattress (LaylaSleep.com)

Most modern mattresses are single sided.

But if you’re looking for a double sided mattress with a lifetime warranty then the Layla Hybrid could be perfect for you.

The coil core and double sided design not only makes for a durable mattress that could last you longer than a single sided mattress, one side is soft and the other is firm to appeal to front, back, and side sleepers of different weights.

There’s also a 120 night sleep trial to cover you against comfort issues.

Recommended For

  • Edge sleepers – if you like to hug the edge of the bed then the reinforced coils can help to guard against roll-off and sagging.
  • Front and back sleepers – the firm side will likely suit all but the lightest front and back sleepers under 130 lbs by providing the increased surface tension required to keep you in good posture.
  • Side sleepers – the soft side can help to provide more give and pressure relief around your hips and shoulders than the firmer side.
  • Skinny sleepers – if you have a lower body fat percentage then the soft side will provide more pressure relief on the more angular areas of your body than the firm side.
  • Lighter weighted sleepers – the soft side will allow you to sink more into the materials to provide a greater dissipation of pressure in your joints when compared to the firmer side.
  • Heavier weighted sleepers – the firm side coupled with the coil support core can help to provide the support that you’ll need if you’re over 230 lbs to guard against excessive material sinkage.
  • Couples – although this mattress contains coils, they are individually wrapped to dampen motion transfer and the reinforced edges allows you to make full use of the mattress area.

Considerations

  • Sleeps fairly cool – although this mattress contains memory foam, the copper infusion and aerated coil core may help to keep you cool and dry.

Other Benefits

  • Zip off cover – the cover can be zipped off to make cleaning easier.
  • 0% APR- pay with Affirm at checkout to spread your payments out without any extra interest to increase affordability.
  • Get $200 OFF – click the button below to get $200 OFF your new Layla hybrid mattress for a limited time only.

6: Nectar Memory Foam – Cheapest Option

Nectar Mattress Offer
Nectar Mattress Offer (NectarSleep.com)

If the other mattresses on this list are a touch out of your price range but you still want a mattress with a lifetime warranty then the Nectar Memory Foam Mattress could be ideal for you.

Because not only does this mattress cost less than $1,000 for a queen you can get an extra $100 OFF here for a limited time only.

Beyond the better pricing, you’re covered by a lifetime warranty and a 1 year free trial to ensure that you’re protected against defects and discomfort if you’re not happy.

In terms of the mattress itself, the softness of the foam is offset slightly by the medium-firm feel to yield a mattress that’s suitable for a wide range of sleeping positions – including couples too.

Recommended For

  • Side sleepers – the cushioning of the memory foam can help to alleviate the pressure on your hips and shoulders.
  • Back sleepers – the slightly firmer feel coupled with the high density support core can help to keep your spine supported.
  • Front sleepers – although this is an all-foam mattress, the medium-firm feel should provide enough surface tension to support your hips adequately.
  • Couples – the all-foam design can help to isolate motion transfer and dampen movements to limit cross mattress disturbance.

Considerations

  • Sleeps fairly cool – although all-foam mattresses are not typically ideal for warmer sleepers or hotter climates, the ventilated design of the Nectar makes it a fair choice if all of the other specs are ideal for you.

Other Benefits

  • Non-toxic foams – the CertiPUR-US®️ certification means that the foams are free from certain harmful chemicals like PBDE’s mercury, and formaldehyde.
  • Very popular mattress – if you click the button below, you can read through the 20,000+ customer reviews that give the Nectar an almost perfect 5/5 star rating on NectarSleep.com.

How to Buy a Mattress With a Good Warranty

A warranty is a legally binding assurance made by the manufacturer that a good or service is fit for use as represented and will be replaced or repaired if found to be defective at no extra cost to the buyer [3].

For example, if your brand new mattress arrived and it was sagging significantly in the middle because the springs were broken then this would count as a defect and you could claim via the warranty for a repair or replacement in line with the terms of the agreement.

Federal law stipulates that you must be able to read through a warranty before you buy the product – even when shopping online [4].

If you scroll to the bottom of just about any online mattress manufacturer’s website, you’ll see a link to their warranty where you can click through and read the terms.

I strongly recommend reading the warranty in full for the mattress that you’re thinking of buying.

However, given that they are often full of legal-speak and usually presented as a giant wall of unreadable text, it can be difficult to understand everything.

That’s why I’ve put together the 3 step guide below that explains how mattress warranties work and the exact process that you should follow to buy a mattress with a good warranty and avoid voiding it.

There’s also a table that summarises the different types and lengths of the warranties for the most popular online mattress brands to help save you some time.

1: Understand How Mattress Warranties Work

Mattress warranties can be implied or written.

Implied warranties are created by state law and all 50 states have them to ensure that you have some recourse even if the mattress doesn’t come with a written warranty; unless the product is marked as an ‘as is’ sale – where some implied warranties can be disclaimed [5] – or the seller explicitly states in writing that no warranty is given.

‘As is’ sales are prohibited in some states, such as Kansas, Maine, Maryland, Massachusetts, Mississippi, and others.

An implied ‘warranty of merchantability’ means that the product will do what it’s supposed to do, whilst an implied ‘warranty of fitness for a particular purpose’ means that the product is suitable for a particular use.

However, although not required by law, most major online mattress manufacturers offer their mattresses under written warranty – available to read before purchase.

And whilst I discuss the differences between mattress warranties in the next section, it’s first beneficial to understand the general benefits, drawbacks, and terms of operation that affect written mattress warranties on the whole.

Benefits

The main benefit of having a mattress covered under written warranty is that in addition to being covered for defects such as broken coils, faulty seams, and other physical flaws, most manufacturers also provide protection against sagging and body impressions that do not arise through improper use or normal wear and tear (typically starting at 1.5 inches).

Under non-prorated coverage, such defects will be corrected through repair or replacement without you having to pay for them – although you may incur additional costs to cover shipping or inspection.

Drawbacks

The main drawback to written mattress warranties is that you’ll typically have to pay for shipping to have the mattress returned and replaced (but not always), or incur other hidden charges such as to cover home inspection.

Another potential drawback is paying more for a lifetime warranty, when nearly all mattresses will require replacing after 10 – 15 years (usually before) due to normal wear and tear – which isn’t covered under warranty.

Similarly, although a 20+ year mattress warranty may look incredibly generous, upon inspecting the terms, you’ll likely find that the latter half of the warranty is covered under ‘prorated’ coverage – where you’ll be required to contribute to some of the costs of replacing the defective parts.

And as the video below reveals, actually claiming under your warranty can sometimes be less than straightforward.

FOX43 Finds Out: Mattress Warranty Problems (FOX43)

What’s Covered?

Most written mattress warranties will cover the following issues:

  • Defective sagging – premature sagging or sinking that exceeds a certain depth stipulated buy the terms (usually starting at 1 – 1.5 inches, although some brands may start at a lower or higher value).
  • Broken coils – coils that are broken, bent, or push through the material will likely be covered (and may be the cause of defective sagging).
  • Seams, zippers, and handles – seams that have come undone, broken handles, and zippers that don’t work properly are usually covered under the warranty.
  • Bunching – irregular bunching or lumps are sometimes covered if they are related to a problem with the integrity of the materials (such as a manufacturing defect in the memory foam or polyfoam).
  • Broken frame/box spring – if you ordered a compatible frame/box spring and it breaks through no fault of your own, then you may be able to claim under the warranty. However, many mattress manufacturers have separate warranties for their bed frames, pillows, toppers, sheets, and accessories.

What’s Not Covered?

Most written mattress warranties will not cover the following issues:

  • Comfort preferences – mattress warranties don’t allow you to send the mattress back simply because you’re uncomfortable in it (unless the discomfort stems from a defect like broken springs). Thankfully, most reputable mattress manufacturers offer a sleep trial, where you can return the mattress if you find it uncomfortable.
  • Minor sagging – sagging that doesn’t extend beyond the stipulated threshold isn’t covered under warranty.
  • Minor body impressions – body impressions that do not exceed the stipulated sagging threshold are classified as ‘normal wear’ and are not covered under warranty.
  • User damage – damage to the mattress such as tears, burns, staining, and discolouration are not covered under the warranty.
  • Damage through improper care – damage that arises through misuse or improper care of the mattress (such as using the wrong frame) is not normally covered.
  • Normal wear – minor changes in the mattress integrity that are from repeated use over time such as dips and body impressions under the stipulated threshold are not covered.

Validity

In most cases, the warranty will not be valid if the mattress is given to you by – or you bought it from – the original purchaser.

Similarly, buying a mattress from an unauthorized retailer or private seller (such as on Craigslist or an auction site) will usually void the warranty.

Buying the mattress directly from the manufacturer’s website or their showroom is the best way to ensure that the warranty is valid.

Warranty vs Sleep Trial

A mattress warranty is not the same as a sleep trial.

Because whilst a mattress warranty may last up to 10 years or more, it doesn’t allow you to return the mattress simply because you’re uncomfortable or don’t like it – which is what a sleep trial allows you to do.

Most sleep trials last around 3 months (or up to a year or more in some cases) and they allow you to use the mattress as normal and return it for any reason if you’re unhappy with it.

A hidden clause with many sleep trials is that you must try it for a minimum amount of time too (usually 10 – 30 days) – to ensure that you’ve allowed the mattress materials enough time to adjust to your body weight and shape.

2: Check the Integrity of the Warranty

Whilst many of the above generalisations hold for most mattress warranties, there are differences between brands – and even between models for the same manufacturer.

That’s why I recommend reading the warranty in FULL for the specific mattress that you’re considering buying before parting with your cash.

Below are some of the specifics that you should be crystal clear on before moving forward with your purchase.

Full Warranty

A full warranty completely covers the repair or replacement of any qualifying defect within a reasonable amount of time [6].

Limited Warranty

A limited warranty is limited to certain parts, and/or certain types of defects specified by the manufacturer – limited mattress warranties are far more common that full mattress warranties.

Non-Prorated Coverage

A non-prorated mattress warranty means that you do NOT have to contribute to the costs of replacing the defective parts or for a replacement mattress.

However, you may have to contribute to shipping and inspection fees – but not always.

Mattress warranties that last 10 years or less are typically entirely non-prorated.

Prorated Coverage

A prorated mattress warranty means that you must contribute a certain percentage towards the repair of the defective parts or replacement of the mattress.

Mattresses warranties that last longer than 10 years are typically prorated for the final half or in the later years.

Graded Coverage

Many mattresses are split between non-prorated and prorated coverage.

Usually, the first 10 years are non-prorated, with every year thereafter seeing a percentage increase in costs that needs to be contributed by the owner under prorated terms (usually 50% in year 11 and then 5% per subsequent year for a 20 year warranty).

Duration

Most mattress warranties last for 10 years and are non-prorated – although 15, 20, 25, and lifetime (‘forever’) warranties are also available.

Hidden Costs

Even if a mattress warranty is non-prorated, you need to check the fine print to find out if you have to pay for return shipping, shipping of the new parts, inspection fees, or pay for a ‘home inspection kit’ to validate the warranty claim.

This is very important because if you bought your mattress from an overseas manufacturer, then it could cost you $100’s in return shipping – although many manufacturers will waive the shipping fee if the warranty claim is valid, or as standard as part of their terms.

Home inspection fees could cost as much as $40 – $60, whilst a home inspection kit may cost up to $30 to order.

Paying Too Much for a Warranty That’s Worthless

Whilst a 15, 20, 25 or lifetime warranty might sound amazing, you must ensure that you’re not paying extra for this ‘perk’.

Because most mattresses don’t last more than 10 years under normal use (which wouldn’t result in a valid warranty claim) and need replacing – so a longer warranty is pretty much useless in many cases.

Especially when you consider that you can be paying up to 90% of the costs under prorated terms in the later years of a longer warranty (meaning that it would make more sense to just buy a new mattress).

To ensure that you’re not being ripped off, try shortlisting a range of mattresses that you’re interested in with very similar specs and take note of any price spikes where the only major difference is a longer warranty.

3: Do Not Void the Warranty

You should also check the terms of the warranty to ensure that you know what can void the warranty.

Adhering to the following points can often help you to avoid voiding the warranty:

Use the Correct Support

If you use a non-compatible, broken, or inappropriate bed frame or resting surface then this could void the warranty.

For example, if you’re using a slatted base, most warranties will state that the slats must be no more than 3-4 inches apart and that there’s a centre support for queen sized frames and above.

Buying a compatible bed frame from the manufacturer when you order your mattress can help to limit future problems and guard against mattress sagging.

Unbox Your Mattress ASAP

If your mattress arrives compressed in a box – make sure you unbox it as soon as possible.

Some brands stipulate that leaving your mattress boxed for too long can void the warranty (and may stop the mattress from fully expanding).

Do NOT Flip Your Mattresses (Unless Allowed)

The old advice of flipping your mattress to extend its lifespan isn’t really valid anymore because most modern mattresses are ONE sided.

Flipping a one-sided mattress is a bad idea because it will more than likely make the mattress uncomfortable for sleeping, cause damage to the materials, and void the warranty.

If you’re going to flip your mattress, make sure that it’s double-sided.

Rotate Your Mattress (Unless NOT Allowed)

Instead of flipping your mattress, it’s a better idea to rotate it 180 degrees every 3-6 months to ensure that the mattress isn’t being exposed to the same pressure points every night which can otherwise lead to dips, body impressions, and sagging.

However, if your mattress has zoned support or a unique lateral layering design, then you might not be able to rotate your mattress without voiding the warranty because one end of the bed might be designed to support your head and shoulders, whilst the other half has a different design to support your hips and lower back.

Be sure to check the fine print.

Do Not Remove the Law Tag

Whilst the tag that reads ‘do not remove this tag under penalty of law’ is aimed at the seller, most warranties will be void if the tag is removed.

Use a Mattress Protector and/or Topper

Using a mattress topper and/or protector may help to preserve the warranty by protecting the mattress from damage and stains, whilst also helping to extend the lifespan of your mattress.

Take Care of Your Mattress

As well as avoiding doing obvious things like jumping up and down on your bed or placing hot items like hair straighteners on the mattress, you should also make sure that you clean your mattress regularly, and use proper techniques for cleaning the mattress cover.

Brand Specific Warranties

Below is a table that summarises the length, coverage, and qualifying indent depth for the warranties for the most popular online mattress brands.

Please be aware that whilst I’ve done my very best to ensure that this information is correct at the time of publishing, manufacturers may make adjustments to their warranties over time – such as adding or removing terms and/or qualifying mattress models.

And there are more details than I have space to accommodate for here – such as warranties being void in certain states or countries, the exact ratios of the graded coverage, and a range of other sub-clauses.

So you should DEFINITELY check the warranty for YOURSELF before purchasing, and only use the table below as a rough comparison guide to help you quickly identify a warranty that suits you.

Here are some of the answers to the most common questions related to mattress warranties.

How Do You File a Mattress Warranty Claim?

To start a warranty claim for your mattress, you should first review the warranty terms to ensure that you have the basis of a valid claim to save you time (and possibly money) before contacting the retailer or the manufacturer to start the claim. You should ask about the costs involved and follow the steps as advised – which may include an inspector visiting your home or you having to take pictures of the defective part of the mattress.

Which Mattresses Have the Best Warranties?

The mattresses with the best warranties are those with extensive non-prorated coverage (10 years or more), have defective sagging starting at 0.5 – 1 inch, and do not require you to pay for return shipping or have any other hidden fees.

How Long Do Mattress Warranties Last?

Most mattress warranties last for at least 10 years, with some brands offering 15, 20, 25, or even lifetime (‘forever’) warranties.

Which Mattress With a Lifetime Warranty is the Best?

The best mattress with a lifetime warranty is the Puffy Lux because not only are you eligible for a full replacement for free, the mattress itself is suitable for a wide range of sleeping styles.

Plus, there’s the option to choose the hybrid version if you want to have springs for more bounce and support (great if you’re a front sleeper and/or weigh more than 230 lbs).

If you click the button below, you can get $300 OFF the Puffy Lux for a limited time only.
