Molecule launched its first mattress in 2018 and has enjoyed a rapid rise in popularity, in part thanks to its partnership with famous athletes. The Molecule 1 and 2 all-foam mattresses feature three layers of foam with targeted support and pressure relief.

Both Molecule mattresses are designed to keep you cool so you get more slow-wave sleep and wake up feeling refreshed and restored. The company specifically targets people who live an active lifestyle. Aside from mattresses, Molecule also makes sheets, pillows, comforters, duvet covers, pillow shams, pillowcases, mattress toppers, and even a pet bed.

This Molecule mattress review will cover construction, sleep experience, and other information to help you decide if the Molecule 1 or 2 could be the right pick for you.

The firmness of a mattress is one of the major factors that determine how comfortable it will feel. Preferred firmness is subjective and depends on factors like your body type and sleeping style. Most sleepers prefer a medium-firm mattress, which offers the right balance between pressure relief and spinal support. On an approximate scale of 1 to 10, medium-firm would rank around a 6.5.

The Molecule 1 and 2 mattresses are slightly different compared to their predecessor, the original Molecule mattress. While the original Molecule had 3 inches of memory foam and 2 inches of transition foam, the new models have 2 inches of memory foam and 3 inches of transition foam. The transition foam has also been firmed up and now has an ILD of 40 instead of 23.

Thanks to these changes, the new Molecule models will feel slightly firmer than the original, falling around a 6.5 out of 10 on the firmness scale, or medium-firm. The Molecule 2 may feel marginally firmer as the top layer has a density of 3 PCF against the Molecule 1’s 2.5 PCF. Both Molecule mattresses also feature zoned cut-outs, so the head and feet sections will be softer, while the middle section will be firmer.


The Molecule mattresses are available for purchase through the Molecule website. Molecule is not currently present in any showrooms or brick-and-mortar stores. Amazon and Costco both have Molecule product pages but so far the products are not available. The mattresses ship to all 50 US states.

Molecule mattress construction

Molecule recently did some restructuring and now offers two mattresses, the Molecule 1 and the Molecule 2. The Molecule 2 more closely resembles the original Molecule mattress and is sold at the same price point, the major difference being that it now has a thicker, firmer transition layer with 5 support zones instead of 3. The Molecule 1 uses a slightly different foam in the top layer and uses the original 3-zone support system with hexagons and diamonds. It comes at a significantly lower price point.

Both mattresses have three layers of 100% polyfoam. The moisture-wicking cover is made of approximately 99% polyester and 1% elastane. Instead of using flame-retardant chemicals, Molecule encases each mattress in a naturally fire-retardant sock.

Molecule 1

The top comfort layer of the Molecule 1 is made of Molecule’s proprietary RestoreFlo™ memory foam and is 2 inches tall. This open-cell foam is infused with gel microbeads and provides pressure relief, moisture management, and airflow, even when compressed. The foam has an indentation load deflection (ILD) of 9 and a density of 2.5 pounds per cubic foot (PCF).

Underneath this is a 3-inch zoned transition layer of RecoveryFlo™ foam with an ILD of 40 and a density of 1.65 PCF. This layer features 3 zones with geometric cut-outs that provide adapted support for the different areas of the body. The head and feet areas are cut into small diamonds, while the lumbar area has larger hexagons.

The support layer in the Molecule 1 mattress is 7 inches tall and made of ContourFlo™ foam, which is breathable while providing spinal support. This foam has an ILD of 35 and a density of 1.5 PCF.

Molecule 2

The 2-inch top layer of the Molecule 2 is made with a proprietary foam called MolecularFlo™ Extreme Open Cell, designed for enhanced airflow. Molecule claims this foam has 7 times the airflow of traditional memory foam. This foam has an ILD of 9 and a density of 3 PCF.

Next, are 3 inches of the same RecoveryFlo™ foam as in the Molecule 1 mattress, this time divided into 5 zones. The head and feet areas feature varying hexagon zone density and the lumbar area features larger hexagon zones, providing targeted support and pressure relief. Like the Molecule 1 mattress, this foam has an ILD of 40 and a density of 1.65 PCF.

The 7-inch base layer is made of the same firm and breathable ContourFlo™ foam as in the Molecule 1. The breathable cover has an antimicrobial treatment.


The Molecule mattress ships as a bed-in-a-box. Molecule ships with FedEx and mattresses tend to arrive within a week after you place your order. Shipping is free in the contiguous US, with an extra charge for Alaska and Hawaii.

To assemble the mattress, take it out of the box and lay it on its side on the bed foundation. Using the enclosed letter opener, carefully slit open the plastic bags and let the mattress unfurl. The mattress will expand almost to full size within a few minutes, but may need another 24-72 hours to finish expanding completely.

Additional Service

Molecule doesn’t currently offer options for expedited shipping, White Glove delivery, or old mattress removal, although they may add White Glove delivery in the future.

Sleep Trial

Molecule grants a 100-night sleep trial starting on the delivery date. If you decide you don’t like the mattress during this time, you can contact them and they will send someone to pick up the mattress for you. Molecule will provide a full refund for the mattress cost, minus discounts and interest payments. They do require you to wait during a mandatory break-in period of 30 nights so you can allow your body to adjust to the mattress before deciding if you want to return it. Returns are limited to one per customer or household.


The Molecule mattresses come with a limited lifetime warranty that guarantees the mattresses against defects in materials and workmanship. These include indentations greater than 1 inch, manufacturing flaws in the zipper, and physical flaws in the cover such as torn fabric or stitches. The warranty will not apply if the flaws are the result of normal wear and tear, abuse, or improper use. In the event of a defect, Molecule will either repair or replace the mattress with a comparable model. For more information about the warranty, click here.

Molecule Mattress Performance

Motion Isolation
Molecule 1

All-foam beds are often praised for their ability to limit motion transfer, so you can share the bed without your movements affecting your sleeping partner. Memory foam is usually recognized as one of the best materials for motion isolation.

The 2 inches of memory foam in the top layer of the Molecule 1 and the fairly firm layers beneath will absorb most of the motion.

Molecule 2
Edge Support
Molecule 1

A mattress is said to have good edge support when you can sit or lie on the edge of the bed without feeling like you’re falling off. All-foam mattresses often struggle to provide adequate edge support, and this was one of the weak points of the original Molecule mattress.

For the Molecule 1 and 2, the company has firmed up the transition layer, taken away an inch of memory foam, and added an inch to the transition layer instead. The new mattress provides much better edge support and you are less likely to feel the mattress compressing too much underneath you at the edges, especially when lying down.

Molecule 2
Heat Retention
Molecule 1

This is the major selling point of the Molecule mattresses. The Molecule 1 features a low-density open-cell memory foam infused with gel microbeads, cut-out channels in the transition layers, a breathable support foam in the base layer, and a breathable, moisture-wicking cover. All this helps improve airflow compared to a traditional foam mattress.

Molecule 2
Molecule 1

The foams are made using a process called Variable Pressure Foaming, which incorporates air-sealed chambers and carbon beds to reduce harmful emissions. All Molecule mattresses are CertiPUR-US® certified, which guarantees them to be free of ozone depleters and low in volatile organic compounds (VOCs).

You may notice a faint odor upon unpacking the Molecule mattress, which most likely comes from the non-toxic, water-based glue. The scent is not harmful and should disappear within a day.

Molecule 2
Molecule 1

The zoned cut-outs give a softer feel under the head and feet and enhanced support under the lumbar area. The support core of the mattress provides a firm base that keeps your spine aligned.

Molecule 2
Molecule 1

The Molecule 1 mattress won’t produce the “hug” feeling typically associated with memory foam, but the lightweight memory foam in the top layer will help relieve pressure points. The cut-outs in the transition layer are also designed to conform to the shape of the body. These features should reduce most pressure points.

Molecule 2
Molecule 1

The memory foam comfort layer has a fairly low density, but the firm transition layer should help extend the lifespan. The Molecule 1 mattress should have an average lifespan for a foam mattress.

Molecule 2
Molecule 1

Arguably the most important factor that determines whether a mattress will be suitable for sex is whether or not it is resilient. Resilience is the “bouncy” quality of a material that quickly springs back to its original shape once pressure is lifted.

The low density of the memory foam and the resilience of the transition layer will facilitate moving around in bed, which is also good news for combination sleepers. The transition layer is one inch thicker and there is one inch less of memory foam, so this mattress performs better for sex than the original.

Molecule 1

As an all-foam bed with memory foam in the top layer, the Molecule 1 should make little to no noise.

What Type of Sleeper Is Well Suited to a Molecule Mattress?

Side Sleepers: Side sleepers will find that the memory foam and the zoned transition layer in the Molecule 1 and 2 mattresses help alleviate pressure under the hips and shoulders. However, the comfort layer is quite thin so heavier side sleepers may find they sink through the memory foam to the firmer foams below.

Back Sleepers: The transition layer zones of the Molecule 1 and 2 mattresses are specifically engineered to provide support for the lumbar region, and back sleepers should find that both mattresses succeed at this. The Molecule 2 mattress has a more sophisticated zoning design in the transition layer, which will provide better support. The comfort layer will contour the right amount to form a cradle and reduce pressure points.

Stomach Sleepers: The Molecule 1 and 2 mattresses are firmer than their predecessor and therefore more suitable for stomach sleepers, who will find their hips don’t sink into the bed as much. Molecule imposes no upper weight limit for their mattresses, but heavyweight sleepers may do better on a coil mattress.

Our Verdict

Both Molecule mattresses do a great job of relieving pressure, which makes them suitable for athletes or people who experience chronic shoulder or back pain. The Molecule 2 mattress will perform better in this category due to its superior construction and materials.

The Molecule mattresses also sleep very cool for all-foam mattresses. The company stresses that its products help you stay cool so you get more slow-wave sleep for a better recovery. While pretty much any good mattress should help you get more slow wave sleep, it’s true that the Molecule mattresses do sleep cool.

These mattresses are both good picks if you like all-foam mattresses with a bit of bounce. The Molecule 1 offers a nice alternative to the Molecule 2 for sleepers on a budget.
