Unbiased Molecule Mattress Review

Better Slumber

Launched in 2018, Molecule Sleep is quickly gaining attention in the mattress industry for its new technologies that promote quicker recovery and a restful night. Who wouldn’t want comfort, a cool sleep, and faster tissue recovery?

Athletes and doctors put their minds together and designed the Molecule mattress. All the materials and the arrangement of layers are composed to ensure that people rest longer in the deepest sleep stage. At this stage (aka slow-wave sleep), the body undergoes most recovery and restoration.

The Molecule product line has two mattresses, i.e., Molecule 1 and Molecule 2. However, the company also designs mattress toppers, sheets, a bed frame, and bedding.

In this Molecule mattress review, we look at Molecule 1 – the flagship model. Keep in mind both mattresses feature proprietary foam layers. However, Molecule 1 is a more affordable option appealing to the wider market. Additionally, its memory foam has an open-cell structure and is gel-infused. Let’s take a closer look at what this mattress has to offer.

Who Is The Molecule Mattress Ideal For?

Who Won't Love The Molecule Mattress?

Molecule Mattress Layers

molecule mattress layers

The mattress features a proprietary foam and polyfoam composition. In general, there are three layers, standing at a total of 12.25-inch high, which is slightly thicker than an average foam mattress. Here is the breakdown of the layers:

The cover

Molecule Sleep calls it an advanced cover due to the unique combination of materials. Now, in essence, the advanced cover features a unique blend of moisture and heat wicking properties. The technology ensures that the cover creates a microclimate between the sleeping surface and your body.

Remember, body temperature fluctuates throughout the night. Such fluctuations can make sleeping uncomfortable. To eliminate this, the manufacturer embeds a temperature-sensitive polymer within the cover. The polymer dynamically responds to your body temperature throughout the night and adjusts evaporation and cooling.

Also, this zip-off cover is removable and washable while also being highly breathable. All of which add to better hygiene.

Comfort layer: RestoreFlo

This layer lies immediately beneath the cover. It’s the first proper layer, and it’s 2 inches thick. This comfort RestoreFlo area is designed from proprietary foam featuring remarkable pressure relief properties alongside enhanced airflow properties.

Again, the memory foam has an open-cell structure, which encourages airflow and dissipates heat. Surprisingly, the layer has consistent airflow, even when in a compressed state. That implies that, even with your weight on top of this layer, airflow isn’t hampered.

Notice that there is a generous infusion of conductive gel microbeads. These beads are essential for regulation temperature and managing moisture as you sleep.

The comfort layer contours closely to your body, and it has a slow response to pressure. Thus, you sink into the mattress for exceptional pressure and pain relief for troublesome areas like hips and shoulders.

Transition layer: RecoveryFlo

The transition section is a 3-inches thick and made from polyfoam. The importance of this RecoveryFlo area is to offer targeted support to sleepers. That makes it a precision-contoured 3D geometric surface. Therefore, beyond providing targeted support, this transition layer provides self-adjusting support to various parts of the body. Typically, there are three zones:

  • These smaller diamond zones are found at the head and the feet, and they confer a softer feel at these regions.
  • Larger hexagon zones: This zone is precisely at the center of the mattress. It is firmer and offers additional support and superior pressure relief in the lumbar region.

This unique arrangement of diamond-shaped zones (soft) and hexagon-shaped zones (firm) ensures that you get proper support for all body parts. But it is an admirable feature for strict side sleepers as they need to maintain a proper spinal alignment.

The transition layer typically has a quicker response to pressure than the upper comfort layer. Again, it is firmer than the above section too. So when lying on your bed, this layer responds by a certain level of cradling support that prevents you from sinking deeper into the mattress.

The Base: ContourFlo

This is the support core of the Molecule mattress, and it is 7 inches high. The base is designed from firmer (high-density) polyfoam to offer enough support and give shape to the mattress.

Besides offering support to the upper layers, the base ensures that you have a healthy spine alignment. Moreover, its breathable construction and material provide efficient airflow, promoting heat transfer for a more comfortable night’s sleep.

Why Is The Molecule a Unique Mattress?


A unique feature of the Molecule mattress is the zoned support in the transition layer. The design of the polyfoam makes the mattress ideal for almost all types of sleepers. For example, back-side combo sleepers and strict side sleepers get the best hip and shoulder support, in turn, helping with spinal alignment. In summary, the Molecule mattress:

  • Has a micro-climate that regulates cover material
  • Has geometric zoned reflex layers offering targeted and adaptive support

Keep in mind; the foams making the Molecule mattress are manufactured in the USA, and they have met strict environmental rules. The company uses patented technology such as Variable Pressure Foaming, which uses an air-sealed chamber and carbon beds to scrub emissions. Thus, reducing emissions by 97% and consequently removing common off-gassing odors found in traditional memory foam mattresses.

Molecule Mattress Performance

Firmness – Feel and Support

While firmness is a crucial part of any consumer buying a mattress, the overall mattress feel is highly subjective. Essentially, this means different sleepers can find the same bed to have a different feel and firmness. Factors like body shape, sizes, and types play a critical role in determining a mattress’s feel.

On a firmness scale, usually, 1 to 10 – with 1 indicated soft and 10 showing firmest, the Molecule mattress weighs in at 6. That suggests it’s a standard medium-firm mattress, a firmness that fits the sleeping needs of an extensive range of body shapes.

Mattress firmness scale: 6 / 10

The uppermost foam layer responds slowly, which leaves you with a feeling of lying in a gentle cradle. However, this might slightly differ with weight and body shape. Yet, it has a soft consistency, just like traditional memory foam mattresses.

Let’s look at how different sleepers perform:

Back sleeper

As you sleep your back, there is an initial gentle sink into the comfort layer, which is quickly followed by decent support from the base. Ideally, the mattress will conform to the shoulders and the lumbar area while the base offers support. So, these kinds of sleepers get enough support throughout the night – especially for the hip and with good spinal alignment.

Side sleepers

Side sleepers always look for pressure relief considering the increased pressure due to the small surface in contact with the mattress. Being a conforming and zoned mattress, the Molecule 1 offers exceptional pressure-point relief to side sleepers.

Stomach sleepers

The Molecule mattress isn’t a great option if you sleep on your stomach. Stomach sleepers ideally need something firmer since their hips naturally sink too deep into a soft mattress. But then again, that depends on your weight; an average stomach sleeper should find good support and alignment. However, heavier sleepers won’t be comfortable.

Combo sleepers

Combination sleepers love to use Molecule 1 because of the firm base and center, which provide a mid-level bounce. So switching positions can be a little easier. But then again, that depends on weight. Remember, there is an initial sink, which feels very comfortable.

Note: heavier sleepers often prefer a firmer mattress, regardless of the sleeping position. Such a mattress offers them the needed level of support.

Pressure Relief

Molecule 1 performs exemplarily when it comes to pressure and pain relief.

  • Back sleepers – Its medium firmness keep the back in proper alignment and provide enough support.
  • Side sleepers – The comfort layer conforms to the body; side sleepers get a decent amount of pressure relief at the hips and the shoulder.
  • Stomach sleepers – Lightweight stomach sleepers will get excellent pressure relief. However, their heavier counterparts tend to sink more, which takes the spine out of alignment.

Mattress Bounce

The bounce of a mattress indicates the level of mobility you can get. Remember, the Molecule One has a slower response to pressure since it is an all-foam bed. That means little bounce but doesn’t necessarily mean difficulty moving around. So, if you are looking for a mattress to give you a bouncy feel, all-foam mattresses aren’t ideal options. Instead, it would be best if you considered getting an innerspring or latex mattress.

Motion Transfer

Motion transfer is an important aspect to consider if you have a sleeping partner. Usually, your partner’s movements can disrupt sleep – mainly when they switch position or get off or on the bed.

A foam mattress can dampen all movements, and in this test, the Molecule mattress performs exceptionally well. A bed with little to no bounce means it can isolate motion well. So using this mattress, it’s almost sure that your partner’s movements will go unnoticed.

Edge Support

Superior edge support maximizes the sleeping surface of a mattress typically. Besides, they offer a great place to site in case you want to sit on the bed edge for some reason, like tieing shoelaces.

The problem is most foam mattresses struggle in this aspect. This also applies to most bed-in-a-box brands since they compress the mattresses to fit a box for easier shipping.

However, surprisingly the Molecule 1 performs reasonably well. When you sleep on the edge, you’ll feel somewhat secure as there isn’t an overwhelming feeling of falling off the bed. However, when you sit on the edge of this mattress, it compresses noticeably, especially on the top layer. But that isn’t a deal-breaker as it performs to the industry standard.

Temperature Regulation

It’s true; memory foam sleeps hot, but Molecule 1 skews towards sleeping cool. The mattress features an open cell structure to allow free airflow within the mattress. This ensures no stagnation of hot air. Besides, the gel beads help to draw out heat and dissipate it to the environment. Again, this contributes to a cool bed. Nevertheless, the mattress dips a little, which may cause a small amount of heat build-up.
