╔ About the Molecule 2 Mattress ╗
Molecule is a U.S.-based sleep product brand that first launched in 2018. In addition to sheets and mattress toppers, Molecule offers two mattress models known as the Molecule 1 and Molecule 2.
The Molecule 2 is a memory foam mattress shares many similarities with the Molecule 1, including a memory foam comfort layer, zoned polyfoam transitional layer, and high-density polyfoam support core. These two models also measure 12.25 inches thick. However, the Molecule 2 has a slightly denser and firmer comfort layer that gives the mattress a medium (6) feel.
The Molecule 2 also has a 3-inch polyfoam transitional layer, but this material is divided into five distinct firmness zones. The two extra zones are located around the midsection, and intended to offer enhanced support to the sleeper’s lower back.
Both foam layers have densities of 1.65, which is considered high-density, and ILDs of 40, indicating exceptionally firm feels. In addition to providing zoned support, these transitional layers act as buffers between the comfort and support layers, and the material prevents sleepers from sinking too deeply into the mattress.
The Molecule 2’s 7” support core is composed of 1.5 PCF high-density polyfoam with ILD of 35s, indicating a very firm feel.
The Molecule 2 has a medium feel. The comfort layer conforms somewhat closely, but it does not provide as much of a deep, pressure-relieving body cradle as the softer Molecule 1. The mattress is a good option for sleepers who like a balance of body-contouring and even support, including heavier individuals who sink too deeply into the Molecule 1.
The Molecule 2 has a five-zone polyfoam layer which is softer in the area of the shoulders and hips, designed to give your body extra support where needed.
╔ Motion Isolation╗
During our tests, the Molecule 2 demonstrated very good motion isolation. The comfort layers absorb movement exceptionally, eliminating most transfer for co-sleepers.
Our testers noticed significant sinkage on each mattress. This can be attributed to the all-foam designs, as polyfoam – even with a high density – does not withstand compression very well compared to the coils found in hybrids and innersprings.
The Molecule 2 is slightly firmer than the Molecule 1. This makes the mattress more suitable for heavier individuals, but the foam conforms closely enough for many lighter people.
The Molecule 2 performed against this expectation thanks to its open-cell memory foam comfort layer and the moisture wicking cover.
Tuck’s Molecule 2 mattress recommendations:
+ Sleepers who prefer mattresses with moderate firmness levels.
+ People who weigh 230 pounds or less.
+ Couples. The Molecule 1 and Molecule 2 each absorb motion and isolate transfer very well, and both beds are virtually silent when bearing weight.
The Molecule 2 mattress is not recommended for:
– People who weigh more than 230 pounds. Despite being more firm than the Molecule 1, the Molecule 2 is still body-conforming and may not be firm or supportive enough for sleepers in the heavyweight group.
– Sleepers who prefer more responsive mattresses. The Molecule 2 responds to the body slowly and conform very closely, resulting in a feeling akin to sleeping “in” the mattress
