Construction and Materials

The Molecule is a 12″ all foam mattress made up of 3 layers of various foams: 

  • 3″ Top comfort layer – This layer is 3″ of MOLECULARFLO foam designed to provide cooling and stimulate faster muscle recovery. This proprietary foam is similar to memory foam but it is open-cell and allows greater airflow through the mattress and is effective in cooling even when compressed totally by your body weight. The foam also responds slowly to pressure, allows deep body contouring and provides cozy support.
  • 2″ Transition layer – This layer is 3″ of RECOVERYFLO foam and it is made of series of hexagon and diamond shaped channels that adapt and conform to the unique curves of your body, promote airflow and aid in cooling.
  • 7″ Base layer – This layer is 7″ of firm but breathable CONTOURFLO foam that acts as the foundation for the layers above, helps the mattress retain its shape and extends its lifetime. It also provides good support for a healthy spine alignment, further promotes airflow and helps dissipate excessive body heat.

The cover of the Molecule mattress is made of the advanced hypoallergenic material that dynamically responds as the temperature of your body changes throughout the night and effectively wicks moisture and dissipates body heat to keep the things cool and comfortable. It is breathable, soft and extremely comfortable and adds to the overall luxurious feel of this mattress.

Firmness & Support

The Molecule mattress is a universal comfort type all foam mattress designed to appeal to a wide range of sleepers and we felt it to be a medium soft mattress, coming in around a 5/6 out of 10 on the firmness scale (10 being the firmest).

The mattress has a very soft top comfort layer, then a firmer transition layer and a firm base layer beneath which work together to give the mattress a somewhat softer feel. Kaye felt it to be a little firmer than I did, but as we always tend to mention, firmness is largely weight dependent and I compressed the top comfort layer more than Kaye did since I weight considerably more than she does (230 lbs vs.115 lbs).

For me personally, the Molecule is on the softer side as my heavy weight quickly pushed through the soft top comfort layer and compressed it quite a bit. My weight was fairly distributed when lying on the mattress, but when I sat up in the bed, I compressed the top comfort layer and felt more of the firmer transition and base layers below.

The top foam layer was soft to the touch and responded slowly to the pressure which as the result had some nice body contouring. There is not a lot of bounce to this mattress which makes you likely to sink down through the top comfort layer quite a bit. This makes the Molecule mattress ideal for side sleepers while stomach and back sleepers may need a firmer support.

We are primarily side sleepers and we felt this mattress to be perfect for this position. The soft foam on the top molded to our shoulders and hips and provided us with a nice pressure relief while the firmer support and base layers below supported our bodies and prevented us from sinking all the way down through the mattress.

As a heavier sleeper I felt more of these firmer layers as I pressed through the soft upper layer, but they were quite comfortable and did not cause numbness or stiffness in my hips and shoulders or any other discomfort.


The Molecule is a rather comfortable mattress although it’s more on the softer side as mentioned. Its plush top offers incredible comfort and pressure relief while its firmer foam layers beneath have enough firmness necessary for good support.

The exterior of the Molecule is very soft and comfortable, and the top comfort layer does a good job of providing a comfortable sleeping surface. The softness of the cover combined with the initial soft response from the upper foam layer made for a comfortable night’s sleep and this was shared by both of us.

Furthermore, this mattress is designed to be highly breathable in order to promote better temperature regulation. Its layers are made of special open-cell foams with air channels for increased breathability and airflow which helps the mattress stay cool while you sleep.

Sleeping Hot

The Molecule mattress is very effective when it comes to temperature regulation and heat dissipation. It has a large number of features that promote better heat regulation and cooling.

The various foams used in the construction of this mattress are specially designed to promote greater breathability and airflow, prevent the build-up of excessive body heat and keep you cool and comfortable all night long.

In addition, the cover of the Molecule is also designed to wick away both heat and moisture and help you stay dry and cool even if you are prone to overheating and sweating during the night.

We did not feel any discomfort or stickiness that is often the case with all foam mattresses, and this was something we really were thankful for.

Sinkage & Motion Transfer

As we always preach, sinkage and motion transfer are highly dependent on sleeper’s weight. I weigh considerably more than Kaye, around 230 lbs, and I tend to sink a lot more into the mattress when sitting up or on the edge.

This was particularly true of the Molecule mattress. I quickly compressed the soft top comfort layer and felt more of the firmer foams below which prevented me from sinking further down into the mattress and bottoming out. However, when lying flat on the bed during the night, the mattress did a good job of supporting my body evenly.

Kaye did not experience the same amount of sinkage as she weights half of what I do. The nice 12″ thickness of this mattress combined with the firmer foam layers did a good job of distributing our weights evenly across the bed and did not cause that common phenomenon of her “sinking in a hole” or rolling towards me.

Edge support when sitting near the edge wasn’t the greatest with the Molecule which was again due to my heavy weight (230 lbs).

As for motion transfer, there was some amount of it when I adjusted positions during the night which again is to be expected from the weight differential, but not too much given the fact that it’s an all foam mattress which as a rule always do well with minimizing motion transfer.

All in all, the Molecule mattress does a fairly good job with sinkage and motion transfer, on par or better than many other 10″ all foam mattresses.

Smell / Off-Gassing

The Molecule mattress had a slight off-gassing smell when we unboxed it, which was above average when compared to the other mattresses we have reviewed.

This is to be expected given its all foam construction and the fact that it comes tightly compressed and packed into a plastic package. However, there is no need to be concerned as this smell is normal and non-toxic and will dissipate withing a few hours.

Customer Service

Molecule provides pretty much the standard amount of customer service offerings you can expect from a “Bed-In-A-Box” online mattress retailer. This includes:


The Molecule is somewhat higher priced when compared to other all foam mattresses we have reviewed, coming in at $1499 for a Queen, (but you can Save $200 on a Molecule by clicking here and entering code TALK200.  This is actually a good price given the quality materials used in the construction of this mattress and the overall comfort it provides.

Twin XL$1149
Cal King$1949


All in all the Molecule mattress is a great mattress designed for those who lead an active lifestyle and who are looking for a comfortable all foam mattress that sleeps incredibly cool.

It can be a good fit for you if you prefer sleeping on your side as its top comfort layer will perfectly mold to your shoulders and hips and allow you to sink into foam to a certain degree to prevent the appearance of pressure points while the firmer support and base layers bellow will work to provide you with the right amount of support and keep your spine properly aligned.

The mattress offers that classic memory foam feel and hug and yet it won’t cause you to sink too deep into foam and feel enveloped by it. It doesn’t make moving around in bed difficult and doesn’t cause sweating and the feeling of stickiness usually present with many memory foam mattresses.

A soft and breathable cover works perfectly with the breathable open-cell foams to prevent the build-up of heat and keep the things cool all night long so you can get some quality night’s sleep.

The Molecule mattress is a high-quality all foam mattress that delivers on its promises. We hope that our Molecule mattress review helped you evaluate this great mattress!
