If you’re thinking about buying the Molblly 14 inch, ventilated gel memory foam mattress in a box then you might be wondering if this mattress really can help you to sleep cool and if it’s going to be comfortable or not.
The Molblly 14 inch, ventilated gel memory foam mattress may sleep cooler than other memory foam mattresses due to the breathable cover and the inclusion of the cooling gel but very warm sleepers may prefer a spring or hybrid mattress that doesn’t contain memory foam for maximum cooling.
The rest of this article reviews the Molblly memory foam mattress in more detail so that you can decide if this mattress is right for you or if you would rather choose a different high-quality mattress.
Molblly Memory Foam Mattress Review
To summarise my findings quickly, I would say that this Molblly memory foam mattress is suitable for lighter weighted front, back, and side sleepers – with 200 lbs – 230 lbs being the upper limit in my view.
And I think that if you have a body type that’s skinny or ‘bony’ then you’ll really enjoy the pressure relief provided by the memory foam.
However, I wouldn’t recommend this mattress to heavy people over 230 lbs and/or edge sleepers due to the lack of edge support and greater risk of sinkage overall.
Combination sleepers who switch positions may also dislike the memory foam feel due to the slower response time that makes it harder to switch positions easily.

Molblly Design Analysis
With a 14 inch profile, this Molblly mattress is medium-thick and comprises of 4 individual layers.
Here’s a layer-by-layer breakdown of this Molblly memory foam mattress.
The knitted jacquard cover is soft, breathable, hypoallergenic to reduce the chance of an allergic reaction, and can be removed for easy washing to make maintenance and cleaning a breeze.
2) Comfort Layer
The comfort layer of a mattress refers to the section of the bed that responds to your body shape in order to relieve tension on prominent areas like your hips, shoulders, and knees to keep you comfortable.
And this Molblly mattress leverages 3 inches of gel infused memory foam that adapts to your exact body shape by taking your body heat and using it to reconfigure the molecules of the foam which results in a mattress that feels like it’s hugging you.
This contrasts with the traditional upholstered layers of a regular spring mattress that doesn’t allow you to sink as far into the materials – potentially causing increased pressure on the more angular areas of your body.
And beneath the memory foam, you’ll find 2 inches of higher density comfort foam that provides resistance and bounce.
Overall, I would say that the memory foam comfort layer is going to feel great if you have a slighter build because the foam can work with your ‘bony’ body type to alleviate pressure and increase comfort – although average, athletic, and softer body types are by no means excluded either!
3) Support Core
What is the support core?
Well, whilst the comfort layers of a mattress handle the pressure relief, the support layers are there to ensure that you don’t sink too far into the mattress and at the same time provide enough support for your spine and joints to keep them correctly aligned.
This Molblly mattress consists of 2 layers that collectively contribute to 64% of the mattress depth to ensure that you’re well supported.
This bias towards support is important when it comes to all-foam mattresses because if the lower density comfort layers take up too much of the mattress depth then you’re at risk of excessive sinkage which may cause discomfort – whilst increasing the probability of you being engulfed by the materials which would make it harder to move around.
More specifically, the support core begins with a 1 inch transition layer of soft foam to relieve pressure whilst working with the subsequent layer of 8 inch high density support foam that stabilises the mattress and provides adaptive support for your spine and joints.
Molblly Performance Analysis
In my view, the stand out feature of this Molblly mattress is its memory foam comfort layer that can adjust precisely to your body shape to relieve pressure and increase comfort when compared to a traditional spring mattress that has a non-memory foam top layer.
However, it’s important to note that this enhanced level of pressure relief comes at the cost of a slower response time – meaning that the Molblly is likely to feel more spongy and gloopy when compared to mattresses like the Casper hybrid that have a more responsive top layer over the top of their memory foam to make switching between positions smoother.
Also, the edge support isn’t the best in my opinion either – which increases the risk of roll-off and minimises the total mattress area that can be used.
But the Molblly is hypoallergenic – giving it the power to potentially help you overcome sensitive skin and respiratory allergies like hay fever as you sleep.
More details below.
I’d personally rate this 14 inch Molblly memory foam mattress as being medium-soft.
This means that if you’re in the ‘average’ body weight range of 130 lbs – 230 lbs then when you lie down on the mattress you’ll notice an initial softness that arises as the lower density 3 inch memory foam comfort layer sinks under your body weight.
Then as the foam adjusts, you’ll begin to feel an underlying level of firmness that comes from the 2 inches of higher density comfort foam to stop you sinking too far into the mattress whilst also allowing the push back of the even denser support core to bleed through – providing contoured support for your spine and joints.
However, the precise feel of this Molblly mattress will vary depending on your body weight, body type, and dominant sleeping position – which I’ll help you to better understand in the upcoming comfort analysis section.
2) Pressure Relief
Because this Molblly mattress uses memory foam in the comfort layer, the bed will feel like it’s hugging your body.
This means that you can expect very precise pressure relief on the most angular areas of your body whilst also experiencing deeper comfort as the foam gradually adjusts to the more intricate recesses and protrusions – such as your shoulder blades, lower back, and individual vertebrae.
You’re unlikely to experience this level of precision moulding with traditional innerspring mattresses because the top layer cannot adjust individually to each part of your body like memory foam can.
One of the biggest concerns that people have when purchasing an all-foam mattress like this one is if the support will be sufficient to hold their body weight.
This is a legitimate concern because if the upper comfort layers are too soft and/or take up too greater percentage of the overall mattress profile then even average weighted sleepers may find themselves sleeping on what feels like a semi-inflated bouncy castle!
But I personally don’t think that this will be much of an issue if you weigh below 200 lbs because this Molblly mattress features 2 inches of high density foam in the upper comfort layer and 8 inches of high density foam in the base that works with the memory foam to provide contoured support that extends throughout the depth of the mattress.
This means that you’ll feel the pressure being relieved on your joints whilst they are simultaneously cradled to keep them aligned and pain free.
4) Moving Around
People who have never slept on a memory foam mattress are often disappointed to find that this type of foam can lead to you feeling like you’re being sucked into the mattress due to the slow recovery time of the materials.
Now, moving around in this Molblly mattress might not be the worst if you’re under 200 lbs due to the 2 inches of high density support foam that sits below the memory foam layer to increase the buoyancy of the mattress.
But because the memory foam layer is the one that you’ll be interacting with initially, you should be aware that this Molblly mattress is definitely going to have a slower recovery time when compared to a mattress that has its memory foam layer beneath a more responsive top layer like the Casper hybrid mattress.
This puts combination sleepers at a disadvantage because position switching become harder.
With this being an all-foam mattress, the absence of any springs means that the Molblly makes for a very quiet mattress.
Now, if you do experience noise then you should check your frame to ensure that it’s correctly assembled – since creaky beds are often the consequence of an issue with the base rather than the mattress itself.
6) Maximum Weight Capacity
Although not explicitly stated, I’d expect this 14 inch Molblly mattress to be able to hold somewhere in the region of 400 lbs – 500 lbs for the double sleeper sizes.
However, I personally don’t think that the Molblly is a good candidate to be pushed to the limit in terms of weight capacity.
Because although the higher 14 inch profile and high density support core are capable of providing tremendous contoured support to a certain point – the all-foam design and plusher firmness increases the risk of premature sagging and indentations when greater weights are involved.
However, the thicker profile may allow the Molblly to hold more weight than a thinner all-foam mattress with otherwise equal properties.
Personally, I’d say that 200 lbs – 230 lbs is the upper weight limit per person for this type of mattress.
If you weigh more than this then I’d recommend going for a bed that contains springs – such as the Layla hybrid that combines robust support with outstanding pressure relief through its ergonomic and double-sided design.
If you sleep as a couple then you’ll benefit from the all-foam design that naturally inhibits movement and cross motion transfer which decreases the chance of you waking each other up as you shuffle around in the night – a real problem with regular spring mattresses that can sound like a tuning fork when you turn over and one of the coils pings violently!
However, weight distribution is something that you’ll need to consider.
Because even if you’re both under 230 lbs, if one of you is very heavy and one of you is very light then this sort of uneven distribution on an all-foam, memory foam topped mattress like the Molblly can lead to indentations, dips, valleys, and peaks forming.
You might be able to mitigate this by rotating your mattress once every 3 months to distribute the load more evenly – but I think that a more robust hybrid mattress is the answer in such a situation.
And finally, with this being a plusher mattress, you’ll want to ensure that you each have sleeping styles that work with the Molblly – more guidance on this in the next section.
8) Edge Support
Sadly, the edge support for this Molblly mattress isn’t the best in my opinion.
This means that if you’re an edge sleeper then you’re at risk of rolling out, and you won’t be able to make full use of the mattress area either.
Despite the shortcomings of the Molblly’s edge support, this mattress does redeem itself when it comes to helping you battle allergies and skin irritation.
Because the cover is hypoallergenic – which means that it can help to minimise the chance of you reacting with the materials of the bed whilst also working with the all-foam design to inhibit allergen uptake.
This means that when you lie down on the Molblly mattress, you’re less likely to get a lung full of pollen or dust mites – thus helping to minimise the chance of an allergic reaction if you have hay fever or other respiratory allergies.
10) Temperature Regulation
Memory foam mattresses tend to sleep hot – making them a poor choice in an absolute sense when it comes to sleeping cool.
However, this Molblly memory foam mattress has features that help to combat this and may in fact help to regulate your temperature as you sleep.
The main feature being the cooling gel that’s infused into the memory foam layer to mitigate heat retention – further enhanced by the breathable top cover.
The bottom line here is that if you’re a very hot sleeper then the Molblly probably isn’t the best choice for you.
However, temperate sleepers should be fine – especially if you’re using a cooling bed sheet set too.
11) Keeping You Dry
It’s possible that the cooling properties of this bed may help you to stay dry.
But if you sweat a lot then you’ll probably want to leverage the properties of a bamboo bed sheet set to allow moisture to be absorbed and pushed towards the edge of the sheet where it can evaporate faster.
The CertiPUR-US® foams used in the Molblly means that the low VOC count makes for a mattress that’s less likely to smell ‘new’ after opening.
Long term, the hypoallergenic cover makes it harder for mold to grow – making for a more hygienic and less smelly mattress overall.
13) Pain Management
If you tend to experience numbness or tingling when lying in your current mattress then the memory foam comfort layer of the Molblly may be able to get rid of this by removing pressure points.
Also, because this is an all-foam mattress you’ll typically find that your body weight is distributed more evenly throughout the mattress to increase comfort – whilst the lack of springs means that you’re unlikely to experience an uncomfortable concentration of pressure around your hips.
The capacity for pain reduction associated with conditions like arthritis improves with the Molblly mattress because the foam can better adjust to your unique joint and soft tissue positioning to reduce pressure in those areas when compared to a less adaptive non-memory foam mattress.
But as always, I would recommend talking to your doctor before you buy a mattress for your specific health condition.
14) Cleaning and Maintenance
The cover is removable and can be washed to make cleaning and maintenance easier.
I also recommend that you go for a deep pocket fitted sheet to accommodate the 14 inch mattress profile – so that you’re not constantly having to retuck the sheet as it pops off night-after-night due to lacking sufficient depth.
15) Price v Value
I think that the Molblly is fairly priced when compared to the rest of the all-foam memory foam mattress market.
Molblly Comfort Analysis
It’s my view that your dominant sleeping position, your body weight, your body structure, and how they interact with the qualities of a mattress are the primary factors that dictate how comfortable you’re going to be.
And due to its plusher feel, memory foam top layer, and 14 inch all-foam design, I personally feel that this Molblly mattress is best avoided by sleepers over 230 lbs due to sinkage and mobility concerns.
Conversely however, I think that these same qualities make the Molblly ideal for lighter and average weighted sleepers – especially if you’re of a ‘bony’ body type because the memory foam will take away the pressure on the more angular areas of your body.
Here’s a more detailed breakdown for each sleeping position.
1) Front Sleepers
Front sleeping on this mattress should be fine if you’re under 200 lbs – any more and there’s a risk that you might sink too far into the materials and end up with back pain in my view.
2) Back Sleepers
Sleeping on your back is more forgiving on your lower lumbar area when compared to being on your front – so I think that you’ll probably be able to get away with sleeping on the Molblly in this position up to around 230 lbs.
3) Side Sleepers
I personally think that the Molblly is best suited to side sleepers because of its plusher feel and memory foam top layer that can take away the discomfort on your shoulders that you’d typically feel on a firmer mattress.
4) Combo Sleepers
If you’re the sort of sleeper that switches positions often during the night then I don’t think this is the best mattress for you due to the slower recovery time of the memory foam – although you might be ok if you’re under 200 lbs.
5) Edge Sleepers
I don’t recommend the Molblly if you’re an edge sleeper because the edge support isn’t that great in my opinion.
Can This Molblly Mattress Really Help You to Stay Cool?
Yes and no.
Yes – because it contains cooling gel and a breathable cover that could help you to sleep cooler when compared to a memory foam mattress that lacks such properties.
No – because memory foam is notorious for retaining heat.
The bottom line here in my view is that if you’re a hot sleeper then you should go for a spring or hybrid bed that also has cooling capabilities because the more aerated coil support core will help you to sleep at a more ideal temperature.
But if you’re a temperate sleeper then you should be ok with the Molblly overall.
How Do You Set Up the Molblly Mattress?
This is a bed-in-a-box mattress that will arrive at your door in a compressed package.
The box weighs between 80 lbs (full size) and 120 lbs (king size) so you’ll probably need a few bodies to help you move it to your sleeping space.
Here, you should unbox the mattress and place it on your bed frame – cut away the final layer of packaging and watch your bed expand to its full size.
Full decompression may take up to 72 hours but you should be able to sleep on your Molblly mattress in a few hours.
What Are the Compatible Frames?
Molblly don’t make it clear what the compatible frames are for this mattress.
However, from experience I can tell you that all-foam beds like this Molblly mattress are best supported by either a solid platform base or a slatted base – with uncurved, wooden slats that are no more than 3-4 inches apart.
Foam mattresses don’t do well on thin, metal slats or wire frames.
The Molblly MIGHT work with an adjustable base but the 14 inch profile may make it crease heavily – thinner mattresses do better with adjustable frames normally.
How Durable is the Molblly Memory Foam Mattress?
Durability is a slight concern for me with the Molblly if I’m honest.
Because I don’t know the exact density of the upper memory foam layers and the all-foam design may not do well under maximal loads over time.
However, the 14 inch profile potentially makes it more durable when compared to similar, but thinner all-foam mattresses.
I’d hesitantly estimate to getting 5-7 years’ of solid use out of this mattress but this is just a rough guess and will depend on several factors such as individual care and weight distribution.
Will This Mattress Sag?
Because all foam mattresses are generally more at risk than hybrid and spring mattresses of comparable quality – especially under uneven loads.
But if you rotate your Molblly memory foam mattress every 3 months and don’t expose it to very heavy or uneven loads then the risk of premature sagging goes down in my opinion.
Can You Flip This Mattress?
Don’t flip your Molblly mattress because this will cause you to sleep on the higher density support foam, whilst the upper comfort layers are crushed under your weight – the perfect recipe for discomfort and mattress damage!
Is There a Sleep Trial?
I don’t think so.
So you’ll be at the mercy of the return policy of the retailer that you purchase from.
Is There a Warranty?
Your Molblly memory foam mattress is covered by a 10 year warranty.
- Removable cover to make cleaning easier.
- Plusher feel makes the Molblly attractive for side sleepers due to the ergonomic comfort provided for your hips and shoulders.
- Excellent comfort potential for lighter weighted sleepers with a ‘bony’ body type due to the plusher feel and memory foam that provides contoured pressure relief all over your body.
- High density core provides support for your spine and joints.
- May sleep cooler when compared to other memory foam mattresses that lack added cooling properties like the cooling gel and breathable cover.
- The all-foam design makes for a quiet mattress.
- Good for couples due to the thick profile and foam that absorbs movement well so that you can sleep undisturbed.
- The hypoallergenic cover and all-foam design make it a good choice for the control of respiratory allergies like hay fever because the particles are less likely to penetrate the materials where they might otherwise be inhaled and cause a reaction.
- Reasonably priced.
- Poor edge support – limiting mattress area usage and making life difficult for edge sleepers and couples.
- The slower recovery time of the memory foam top layer may make this mattress unsuitable for combination sleepers who switch positions often and don’t want to get bogged down in the materials.
- Not a good mattress to be pushed to the limit in terms of excessive weight due to the potential for increased sinkage and decreased durability.
- Unsuitable for very hot sleepers due to the heat retention of the memory foam.
Here are my final ratings out of 5 for the Molblly 14 inch memory foam mattress.
|Value vs Price||3|
Who Should Buy This Molblly Memory Foam Mattress?
- Front sleepers – 100 lbs – 200 lbs.
- Back sleepers – 100 lbs 230 lbs.
- Side sleepers – 100 lbs – 230 lbs.
- Allergy sufferers looking for relief.
Who Should Avoid This Molblly Memory Foam Mattress?
- Heavier sleepers over 230 lbs will probably sink too far into the materials.
- Front sleepers over 200 lbs may not have enough lower back support.
- Edge sleepers are at risk of rolling out due to the lack of edge support.
