The Molecule Mattress is a three-layer memory foam mattress. The bed is constructed with a ‘Medium’ memory foam comfort layer, a transitional layer made of convoluted polyfoam, and a high-density polyfoam base layer. The cover is made of stretch-polyester with moisture-wicking properties.
The top layer is exceptionally soft, with an indentation load deflection (ILD) of 7 to 9. As a result, sleepers tend to sink somewhat deeply. The convoluted transition layer, which has diamond-shaped projections, also contour closely to the sleeper’s body. These features make the bed suitable for those with chronic aches and pains in their neck, back, and other sensitive areas.
The Molecule Mattress also isolates motion very well and produces virtually no noise when bearing weight. This makes it a good fit for couples. And at 12″ thick, the mattress is a good option for sleepers who prefer higher-profile beds; many competing memory foam models are 10″ thick or shorter.

What Type of Sleeper Is Best Suited for a Molecule Mattress?
Based on our customer feedback, Molecule mattresses have received the following grades among sleepers of different weights and preferred sleep positions.

Molecule offers a lifetime limited warranty on all mattresses.
This warranty is entirely nonprorated.
Molecule will, at its sole discretion, repair or replace any defective Molecule Mattress for the duration of its ownership.
This warranty is contingent on proper foundational support. Per Molecule: ‘Your Molecule Mattress is designed to work on a firm, solid, non–spring foundation or adjustable bed base that is sufficiently strong and stable so as to be capable of supporting the weight of the mattress and its occupants. Failure to use an appropriate foundation will void your Limited Warranty.’
The warranty will cover the following defects:
Sagging or indentations in the sleep surface that measure one inch (1″) or deeper.
Manufacturing or physical flaws in the cover, including broken zippers or unraveling stitches, that are not associated with improper use.
The warranty will not cover the following:
Sagging or indentations in the sleep surface that do not measure one inch (1″) or deeper, or normal increases in foam softness that do not affect its pressure-relieving abilities. These issues are considered normal wear and tear.
Repair or replacement requests that occur due to changes in the owner’s comfort preferences.
Burns, cuts, tears, stains, and other types of physical damage that occur due to inadequate foundational support or owner misuse.
If a claim needs to be made, owners must submit a written description and photographic evidence of the defect, along with the original order number and name of the person who placed the order. Molecule will respond to warranty claims within seven business days.
This warranty is exclusively offered to original owners who purchase their mattress from Molecule or an authorized retailer. Those who buy or acquire their mattress from the original owner or a non-authorized retailer will not be eligible for warranty coverage.
