Molecule is an online mattress company, and it offers two mattress options: the flagship Molecule 1 Mattress and the Molecule 2 AirTEC Mattress. This review will focus on the Molecule 2 AirTEC Mattress.

Although the two mattresses have many similarities, the Molecule 2 AirTEC Mattress has technological features and additions that make it more expensive than the flagship model. The Molecule 2 has a 5-zone transition layer that targets areas to support, whereas the Molecule 1 has only 3 zones. The Molecule 2 is also slightly firmer than its counterpart, though both rate at a medium firm (6) on a firmness scale out of 10. Both models are made of low-density foam, but the Molecule 2 has a higher density than the Molecule 1.

The Molecule 2 distinguishes itself from the flagship in several other ways. It has a layer of open-cell AirTEC foam. This foam has more airflow than traditional memory foam, ensuring better temperature regulation. The mattress has an additional BioCHARGE crystal-infused layer that is designed to improve circulation. The mattress is also treated with Microban to help prevent the growth of bacteria, mold, and mildew.

We’ll perform a full breakdown of the construction, materials, and performance of the Molecule 2 AirTEC Mattress, as well as sleep trial, shipping, and warranty policies from Molecule.

Mattress Performance

Motion Isolation

The Molecule 2 AirTEC Mattress rates above average for isolating motion. Foam mattresses are known for limiting the transfer of motion across the surface of the bed.

Motion isolation is important for sleepers who share their bed with a partner, children, or pets. Sleepers on the Molecule 2 AirTEC Mattress are likely to be undisturbed by movements from others during sleep.

Pressure Relief

The conforming properties of the Molecule 2 AirTEC Mattress provide above-average pressure relief to sleepers.

The AirTEC foam layer contours to the body so that heavier parts—hips, shoulders, and the head—are relieved of pressure. The RecoveryFLO layer of the mattress has 5 targeted and self-adjusting zones to support different parts of the body. The hexagonal zone density varies at both the head and foot of the bed to support the upper and lower body. The center of the mattress has larger hexagonal zones to provide additional pressure relief in the lumbar region.

Mattresses with good pressure relief evenly distribute a sleeper’s body weight so that pressure points don’t form. Sleepers on these mattresses typically experience less discomfort or pain than sleepers on mattresses with poor pressure relief.

Temperature Control

Although all-foam mattresses are known for trapping heat, the Molecule 2 AirTEC Mattress rates average for regulating temperature.

The AirTEC technology of the mattress contributes to temperature regulation. The AirTEC layer of the mattress is composed of open cells that encourage airflow even when compressed. Additionally, both the cover and ContourFLO support core are designed to increase airflow and provide a cool sleep.

Sleepers who sleep very hot may prefer a mattress that regulates temperature even more.

Edge Support

All-foam mattresses have a reputation for weaker edge support, and this is true for the Molecule 2 AirTEC Mattress.

Beds lacking strong edge support will eventually have sagging edges, resulting in less usable surface area of the mattress. Sleepers on beds with weaker edge support may feel they are at risk of rolling off the bed during sleep. This can also pose difficulties for sleepers who want to sit on the edge of the bed as the edge may buckle or fold under weight.

Ease of Movement

Because the mattress’s 5-zone RecoveryFLO layer is designed to contour to the sleeper’s body, sleepers experience a feeling of sinking into the mattress rather than lying on top of it. This “hugging” property can inhibit quick movement as it takes a few moments for the mattress to bounce back.

Ease of movement can affect activities such as sex or moving into a new position during sleep. Some sleepers may find themselves waking up as they try to roll over while sleeping.


Several factors make the Molecule 2 AirTEC Mattress rate below average for sex. Like many foam mattresses, the Molecule 2 contours to the body and does not have much bounce. Due to the mattress’ conforming properties, partners may experience a feeling of being stuck in the bed. This can cause difficulties in quickly switching positions or moving across the bed. Finally, the lack of strong edge support will limit the amount of usable surface area over time.


The Molecule 2 AirTEC Mattress rates relatively well for off-gassing. Off-gassing refers to the release of Volatile Organic Compounds (VOCs) after unboxing a mattress. The mattress is made with CertiPUR-US certified foam, meaning these gasses do not pose any known health risks. However, the gasses may have a slight odor that dissipates within 24 hours. Molecule notes that any scent associated with the Molecule 2 AirTEC Mattress upon unboxing comes from a non-toxic water-based glue, and the scent should dissipate within a 24 hour period.

Side Sleepers

The conforming nature of the Molecule 2 AirTEC Mattress provides relief to the hips and shoulders, which are common pressure points for side sleepers. These are typically heavier parts of the body, which the AirTEC technology in the second layer of the mattress is specifically designed to relieve pressure from. As a result, side sleepers of all sizes find solid comfort in the mattress, while those who weigh between 130 and 230 pounds find it particularly comfortable.

In terms of firmness, medium firm mattresses like the Molecule 2 are ideal for side sleepers because they prevent the body from sinking too deeply into the bed, while also being firm enough to help ensure proper spinal alignment.

Back Sleepers

Back sleepers require support around the lumbar region to ensure the back doesn’t sink too deeply into the mattress and improperly align the spine. The 5 zones of the Molecule 2’s RecoveryFLO layer provide necessary cushion and support to targeted areas of the body. The center zones are designed to specifically support the lumbar region.

Back sleepers under 230 pounds rate the mattress as good. They will experience the “hug” of the mattress without sinking too deeply into it. However, back sleepers above 230 pounds may find themselves sinking into the mattress more than is desirable.

Stomach Sleepers

Stomach sleepers need good support of the abdomen so that they will not sink too deeply into the mattress. Deep sinkage risks pushing the body into a “U” shape, contributing to improper spinal alignment. Stomach sleepers typically require a firmer bed to prevent discomfort.

Stomach sleepers under 130 pounds will find the abdomen is adequately supported on the Molecule 2 AirTEC Mattress. Unfortunately, stomach sleepers over 130 pounds will likely find themselves sinking too far into this bed to be comfortable. These sleepers will likely prefer an even firmer mattress to ensure the abdomen is properly supported.

Molecule 2 Mattress Review Breakdown

The Molecule 2 AirTEC Mattress is an all-foam mattress. It has a cover, two CertiPUR-US certified polyfoam comfort layers that conform to the body and relieve pressure points, a 5-zone polyfoam transition layer, and a 6-inch support layer.

The mattress cover is a polyester and lycra spandex blend, designed for breathability to promote a cool sleep. The antimicrobial cover helps prevent the growth of bacteria.

The first is the Recovery BioCHARGE layer, a crystal-infused polyfoam designed to improve circulation. The second comfort layer is the AirTEC layer with open-cell foam. This foam encourages airflow, even when the mattress is compressed.

The transition layer, RecoveryFLO, is a polyfoam with 5 zones of varying densities to support different parts of the body. The center zone provides support to the lumbar region, while the zones at the head and foot of the bed target the upper and lower body.

At the base of the mattress is the CountourFLO support layer. This firm layer is made of a low-density polyfoam.

Together, these four layers make the mattress 12.25 inches high. As a result, the mattress may require deep-pocket fitted sheets.

The mattress has a medium firm feel of firmness and rates 6 on a scale of 1 to 10. Mattresses at the center of this scale often appeal to a wide variety of sleepers because they’re not too soft or too firm.

Mattress Prices and Sizing

The cost of the Molecule 2 AirTEC Mattress is relatively expensive for an all-foam mattress. Factors of higher-cost mattresses like the Molecule 2 include lifetime warranties and high-quality construction and materials. For example, the Molecule 2 is constructed with AirTEC foam with large, open cells to increase airflow. Additionally, customers receive their choice of a percale sheet set or sateen sheet set with the purchase of any size Molecule 2 Mattress at no additional cost.

The Molecule 2 is more expensive than the flagship mattress from Molecule, the Molecule 1. While the two options are similar, the Molecule 2 has additional technologies, and therefore performance strengths, that contribute to its higher cost.
