All About Molecule Mattress

• Firmness and Feel

The Molecule is a memory foam mattress. They are known to be soft and conforming. It has only a single firmness option, which many will consider a con. Most sleepers prefer a mattress that is available in a variety of firmness options so that they can freely choose the firmness that suits their sleeping preferences. However, the Molecule is only available in medium firmness. Fortunately, that’s suitable for all sleeping position. So while it’s not perfect, this mattress will at least deliver the goods to a wide variety of customers.

Comfort And Feel Rating: 3.5/5

• Motion Transfer

If there’s one thing that memory foam mattresses do better than all of the other mattresses on the block, it’s motion isolation. If you share your mattress with a noisy sleeping partner who constantly shifts position or wakes up for mid-sleep jaunts to the toilet, you’ll know the importance of motion isolation. The Molecule mattress is certainly no exception to this rule. It’s motion isolation is excellent. You could sleep next to a Tasmanian devil with a pea-sized bladder and still never be disturbed in the middle of the night. That’s important. This is the ideal mattress for couples.

• Temperature

Sleeping cool and comfortable is important for a good night rest. That’s why so many companies make an effort to produce mattresses that regulate temperature. Unfortunately, memory foam mattresses are known to trap heat. That’s because sleepers sink into memory foam, which doesn’t allow the free flow of air in and out of the mattress. Thankfully, the Molecule mattress was designed with an open-cell foam comfort layer and moisture wicking cover. These two materials help to regulate temperature and allow sleepers to sleep cool. So, you get all of the benefits of memory foam without the substance’s biggest drawback. Sounds good, right? It is. Very good, even.

Temperature Rating: 4/5

• Edge Support

Temperature regulation isn’t the only drawback of memory foam though. Memory foam also has poor edge support due to its high rate of sinkage. Memory foam has the tendency to sink in deep when pressure is applied and this goes all the edge of the mattress. Sadly, the Molecule mattress has poor edge support because of the memory foam used in the comfort layer. If you have a tendency to hug the edge of your mattress as you sleep, you will feel yourself slipping. You might even wake up on the floor. That’s not exactly ideal and the big failing of the Molecule. However, obviously this won’t be an issue if you plan to sleep in the center of the Molecule. So, it will only be a problem for some sleepers.

Edge Support Rating: 2/5

• Off Gassing

Off-gassing is a common phenomenon among new products. It’s that “new” smell that we’re all familiar with in everything from cars to shoes. It’s no cause for concern. More of a potential irritation for some sleepers. Depending on the type of materials used, some mattresses off gas for quite and have a pungent smell while some don’t. The Molecule mattress does not. It’s off-gassing odor is minor and dissipates quickly. If this is something that tends to really bother you, consider letting the mattress air out in a well ventilated room before sleeping on it or invest in a mattress cover that will cover the smell. Regardless, all signs of off-gassing should be gone within a day or two.

Off-Gassing Rating: 4/5

Trial And Warranty Rating: 4/5


The Molecule mattress is constructed using a combination of memory foam and polyfoam. The major difference is that memory foam has viscoelastic properties that give it quicker bounce back than polyfoam. Memory foam is also soft in feel while polyfoam is firm. The main materials used in the Molecule mattress include:

  1. A cover made with stretch polyester that has moisture wicking properties.
  2. A comfort layer made with ‘medium’ memory foam.
  3. A transitional layer made with polyfoam
  4. A support layer featuring a high density polyfoam.

Let’s break down these materials individually:

Stretch polyester: Ordinarily polyester does not stretch like other natural materials such as cotton or wool. However, when combined with spandex or any other elastic material, it can become stretchy. The polyester used in the Molecule mattress also has moisture wicking properties which allow it to draw in moisture from the mattress. This helps users sleep cool at night.

Memory foam: Memory foam is one of the most common types of foams used in mattresses. Memory foam has viscoelastic property, this property helps the mattress return to its original shape after pressure has been released. This property is one of the reasons why memory foam has longer durability. Memory foam is also popular for its remarkable motion isolation. Although it tends to trap heat, this problem is avoided when combined a breathable material. Of course, the major reason why many customers prefer memory foam is that it conforms to the shape of the sleeper and helps to relieve pressure.

Polyfoam: Another major material used mattresses, polyfoam is similar to memory foam but does not have the viscoelastic properties. Therefore a polyfoam is a bit more resilient and has the ability to efficiently and effectively support the heavier parts of the body during sleep. This ensures it provides comfort and support at the same time.

The major materials used by Molecule are all chemically produced, so it is not eco-friendly. However, the materials are not harmful.

Sleep Sherpa said:

“The Molecule is not your typical 3 layer foam bed. It looks like one and even feels similar to some others I have tried. What sets it apart is that it is one of the coolest sleeping foam mattresses I have tried. A popular way to address heat issues in mattresses is to use a phase change material in the cover which is cool to the touch but this effect is temporary and eventually, the mattress will heat up. Molecule has designed the foam and cut of the foam for maximum breathability where using phase change materials isn’t necessary.

I found this mattress to be a bit on the softer end of the spectrum and for that it may not be best for stomach sleepers but most back sleepers and definitely side sleepers will appreciate the contouring, cooling and pressure relief this mattress offers”

Jon Auer wrote:

“The Molecule could be a nice fit for some side sleepers as well as those who prefer to sleep “in” their mattress rather than “on” their mattress. Also, while this is an all-foam mattress, it handles the issue of overheating very well. You shouldn’t be sleeping hot on this mattress.

That being said, if you are a larger person, you may have a different experience. When you are on your side, you may press through the soft upper layer and feel those firm layers beneath. Also, back and stomach sleepers of many sizes may need more support than this mattress has to offer.

The Molecule comes with a 100-night risk-free trial, Limited Lifetime Warranty, and free shipping. Financing is also available.

Overall Value and Recommendation

The Molecule mattress is soft at the top, which allows sleepers to sink in. However, they do not sink in very deep because of the polyfoam transitional layer. The mattress has close conformity and it relieves pressure quite well. And don’t forget that lifetime warranty, which is a rare luxury that speaks volumes about how strongly Molecule feels about their product. However, the Molecule mattress is relatively expensive compared to other memory foam mattresses. The mattress also comes in only one firmness option, which some customers might not like, and it has poor edge support. Don’t trick yourself into thinking this mattress is perfect.

That said, this is a darn good mattress and an ideal choice for sleepers who have a big budget to spend. Your bank account might regret this purchase, but you sure won’t. Highly recommended, despite our reservations.
