Molecule is a new brand on the bed-in-a-box-scene promising to use science to help its customers find deep, restorative sleep. But how you might ask? Why with its “air-engineered” flagship mattress outfitted with cooling tech and pressure-relieving foam.
So that definitely sounds good, but how comfortable is the bed actually? I won’t know for sure until I put it to the test, assessing how it feels and how it sleeps to see if it might be the mattress of your dreams.
Continue reading below for my full review of the Molecule mattress. Don’t have time to read it all? Click here to skip to the bottom and check out my review summary.
The Molecule mattress features an all-foam design with three distinct layers, stacking up to just over 12” in height. While this may seem like a fairly typical bed-in-a-box construction, the brand claims the build was specifically conceived to help users achieve optimal “Slow Wave Sleep,” which some experts believe is the most revitalizing kind of slumber.
To sink into this deepest stage of shut-eye, Molecule infused its flagship bed with a ton of cooling and pressure relief properties. Curious to see how all this comes together? Me too! So let’s dive on into these layers.
Cover – Molecule’s advanced cover material actively wicks moisture to help keep things cool throughout the mattress. It’s also breathable and soft, providing the sleeper with immediate comfort.
Comfort Layer – Built with the brand’s proprietary MolecularFlo foam, the comfort layer has a slow response to pressure, allowing for deep body contouring. The material is most similar to memory foam, but its open-cell design helps to combat the overheating so often associated with the classic mattress material.
Transition Layer – Next up, you’ll find a layer of the brand’s RecoveryFlo foam. This section is comprised of a series of hexagonal perforations, which work to adapt and conform to the unique curves of your body, extending the contouring of the comfort layer even deeper into the mattress.
Base Layer – And finally the foundation, which is made up of 7” of high-density poly foam. This layer gives the bed its durability and shape.
After taking a look at the construction of the Molecule, let’s chat about the firmness and feel. I started off by applying light hand pressure to the mattress and found that I was immediately interacting with the gentle comfort layer up top. The material contoured snuggly to my hand, providing me with some satisfying pressure relief. Pushing in further, I could feel just how far into the mattress you’re likely to sink i.e. quite a bit.
Since everyone’s going to feel firmness a little differently, I decided to bring in three other testers to help me figure out how firm the Molecule is. We each took a turn lying on the mattress, landed on our own personal firmness rating and then compiled them together on the graph below.
While feel is always going to be an individual thing, our responses will hopefully give you a good sense of the range you can expect from the mattress.
As you can see, my testers were pretty much in agreement about the firmness of the Molecule, giving it an average rating of 5.25. When compared to the industry standard of 6.5 for medium firmness, it’s clear that this bed is pretty soft.
I personally gave the bed a 5 as I found its top foam layers were soft to the touch and had a slow response to pressure, resulting in some deep body contouring. Since there’s not a lot of bouncy lift to this mattress, you’re likely to sink in quite a bit, which will be great for side sleepers. However, this compression may not do the trick for those in need of some firmer support, such as strict stomach sleepers.
Another important component of a bed’s feel is pressure, or more specifically where you’re most likely to feel pressure points form while lying on top of it. Rather than just describing where these tension spots might crop up on the Molecule, I thought it’d be a better idea to give you a visual representation instead.
To do this, I placed a pressure map on top of the mattress and lied on my back, side and stomach. You can see the results on the image below where pressure is represented from blue (low pressure) to red (high pressure).
Back – Lying on my back, my weight was evenly distributed across the surface of the mattress. I could feel myself sinking far into the bed, which provided pleasant relief to my lower back as the soft foam filled in the space at my lumbar region. While this contouring brought me some fantastic comfort in this position, it did make it difficult to move around and change positions.
Edge Support – Scooting closer to the edge of the bed, I felt fairly solid. While I did detect some deep compression through the top foam layers, I never felt as though I’d fall out of bed.
Side – Rolling onto my side, I experienced wonderful pressure relief as the soft foam top layers contoured to my shoulders and hips, typical problem areas for side sleepers. The cushiony relief at these sensitive spots helped to alleviate tension and made for a super satisfying feel.
Stomach – As I mentioned up top, stomach sleepers tend to prefer firmer mattresses, so the Molecule may be too soft for those of you who doze exclusively on your stomachs. This is because the soft foam is likely to cause a lot of sinkage at your shoulders and hips, which will bend your spine out of an even alignment.

Next up, let’s chat motion transfer, or the amount of disturbance you’re likely to detect from one side of the bed to the other. This test will be particularly important for those of you who plan on sharing your bed with a partner as it’ll key you into whether or not you’ll be bothered by their tossing and turning in the night.
To illustrate this motion transfer, I dropped a 10 lb. steel ball from heights of 4 inches, 8 inches and 12 inches and measured the disturbance it caused: the bigger the lines, the bigger the disturbance.
FYI: Each drop is meant to symbolize a different movement you’re likely to experience in bed, from tossing and turning (4”) to getting out of bed (8”) all the way to full on jumping (12”).
I’d say these are fairly average motion transfer results, which tells me that you’re likely to feel your partner as they move around in the middle of the night. While the MolecularFlo foam in the comfort layer does a pretty good job of absorbing and containing disturbance—especially for smaller movements—you’ll notice the dramatic increase in transfer with each larger interference.
And finally, when buying a new bed, most people want to know whether they’ll feel like they’re sinking “into” the mattress or lying “on top” of it.
To visualize this sinkage, I placed four balls of varying sizes and densities (a 6 lb medicine ball, a 10 lb steel ball, a 50 lb medicine ball, and a 100 lb medicine ball) on the mattress and measured how much they compressed the surface.
The variations in size, weight and density are meant to simulate different body parts and different sized sleepers.
- 6 lb medicine ball: 1.5 inches of sinkage.
- 10 lb steel ball: 2.5 inches of sinkage.
- 50 lb medicine ball: 5 inches of sinkage.
- 100 lb medicine ball: 6.5 inches of sinkage.
This is a lot of sinkage! Though definitely a bit extreme, I’m not super surprised by these results as I’ve been experiencing this deep compression throughout my various tests. As I mentioned earlier, the contouring here would make the Molecule a fantastic pick for side sleepers in need of relief at the shoulders and hips. That being said, you’re likely to feel as though you’re sleeping “in” the bed as opposed to “on top” of it, which could be a dealbreaker for some of you.

Now that we’ve taken a closer look at the Molecule mattress, I want to highlight some of its biggest pros and cons:
- I’ve said it throughout this review, but it bears repeating: this bed would be a great pick for side sleepers! It’s got a gentle vibe to it, complemented by some really satisfying contouring foam in the top layers.
- The bed also sleeps cool, thanks to its moisture-wicking cover and open-cell foam design, which makes the structure extremely breathable.
- And if you’re a fan of the “sinking in” feeling, then you’ll find a lot to love in this mattress as you’re likely to sink in pretty far through the bed.
- While this could be an awesome mattress for side sleepers, the same can’t really be said for those who slumber primarily on their stomachs as the soft foam is likely to send your shoulders and hips out of alignment.
- There’s also not a ton of bounce to this bed, so if you’re on the prowl for some buoyant support, this may not be the mattress for you.
