MOLECULE Mattress Review

Pinterest LinkedIn Tumblr

Today MOLECULE mattresses are widely known for their Air Engineered™ technology.  But in 2018, when Tom Brady, the super bowl champion, was announced as the brand ambassador for MOLECULE products. We knew there will be some pleasant surprises in our MOLECULE mattress review.

The other star athletes who are endorsing molecule are Alex Morgan, Russel Wilson, and Nastia Liukin. And the latest one to join the team in August 2020 is none other than Michael Phelps!

Do we get influenced in our reviewing process by stars associated with the brand?

Not really!

This is a unbaised review with no direct or indirect involvement of MOLECULE in any way. Time to get into the details of this OnMolecule Mattress review.

 Let us look into what makes this bed noticeable and stand out against other mattresses.  In this article, we will verify features and share the results of the engineering claims by the brand. Let us begin with the key takeaways.

Molecule offers two variants of mattresses based on firmness viz. Molecule 1 (M1) and Molecule 2 (M2). Molecule 2 is an enhanced or better version of Molecule 1. MOLECULE 3 (M3) is in production and expected to be launched at the end of 2020.

Both mattresses come with the Air Engineered™ technology. Mattresses are engineered so that you get a balanced sleep and recovery.  The materials and processed used helps in better transfer of heat from the body which helps in restorative sleep.

The mattress is scientifically designed to ease the slow-wave sleep stage of the sleep cycle. This stage of sleep is majorly responsible for body recovery.

It comes with CertiPUR-US® certification and shipped free of cost anywhere in the US. They do charge for shipping to  Alaska and Hawaii. It is compressed and shipped in a box.

The manufacturer uses VPF™ (variable pressure foaming) process to construct its foam. It is an environment-friendly and highly controlled atmospheric pressure technique.  The VPF™ helps to remove off-gassing.

The company offers a lifetime warranty and a free 100-night trial. During the trial period, the manufacturer expects you to try the mattress at least 30 nights before it can be returned free of cost.

The MOLECULE does not provide white glove delivery as of now.

Construction and Structure of MOLECULE Mattress

Construction and internal structure of Molecule Mattress

Before we get into the details of different layers of the mattress. Let us have quick details about the cover of the mattress.

The mattress comes with a breathable cover that can be zipped off.  The cover is 99% of polyester and 1% elastane. The polymer is dynamic enough to adjust to the change in body temperature through the sleep cycle. M2 cover additionally comes with antimicrobial treatment. 

The mattress is constructed with three layers of polyurethane foam.

The first layer is a 2” RestoreFLO™ layer. It is infused with gel-based microbeads for effective temperature and moisture management. This is open-cell memory foam for providing ample airflow and comfort in the MOLECULE 1 mattress.

The first layer in MOLECULE 2 is called MOLECULARFLO™ which more advanced than RestoreFLO™. It is an extreme open-cell foam which is 7 times more effective than normal memory foam.

Both the mentioned layers provide consistent airflow even they are compressed.

The second layer is 3” RecoveryFLO™ in both MOLECULE 1 and MOLECULE 2. But there is a structural difference between Molecule 1 and Molecule 2.

MOLECULE 1 (M1) is a 3-zone dynamic response layer with smaller diamond zones around the head and feet for a softer feel.  Larger hexagon zones in the center for additional lumbar support and pressure relief.

MOLECULE 2 (M2) is a 5-zone dynamic response layer. The region around the head and feet has varying hexagon zone density for head and leg region support. The center has larger hexagon zones for lumbar support.

The third layer is a 7” ContourFLO™  which provides a firm base and acts as the foundation of the mattress. It helps in neutral spine alignment.

Firmness ( feel and experience )

Firmness Scale of Molecule Mattress M1 and M2

The mattress is an overall medium firm which means it should suit all types of sleepers. We would like to have a special mention of the top layer with ILD 9 (Indentation Load Deflection). The ILD being well below 12 makes it very soft to touch and feel.

The firmness is provided by the remaining two layers. The 3-zone and 5-zone and core layer provide the firm experience with some bounce. The bottom layers provide ample support and hold to the body after the initial comfort from the first layer.

The difference between 3-zone and 5-zone middle layer makes M2 a little firmer than M1.

Spine Health

Both M1 and M2 provide good support to the spine in all positions. The top soft layer and bottom layer effectively maintains the spine alignment.

Back sleepers and side sleepers will find the mattresses quite comfortable due to the contouring and pressure relief provided by the shoulder and hip region. It handles the stress extremely well and provides relief at pressure areas.

Stomach sleepers may find it a little softer especially people who on the heavier side. Although in our test, we were convinced the pressure area of hips was well supported. But one of our team members, who is considerably heavier than the rest of us, was not fully convinced.

So heavier people can avail risk-free 100-night trial so that they are fully satisfied.

Motion Transfer

Molecule 1 and Molecule 2 provide excellent motion isolation. Whether it’s you or your partner, moving in and out of bed, the co-sleeper will sleep peacefully. You can toss and turn on the bed without the fear of disturbing the sleep of your partner.

This is the highlight of the MOLECULE.

Edge Support

Edge support is generally not the strong point of memory foam or bed-in-box mattresses. We were happily surprised to see it perform under acceptable range. There is considerable compression when you sit on the edge. But it holds well and you don’t feel insecure even if you are sitting for a longer period of time.

Common Questions About Molecule

  1. Is it recommended for stomach sleepers?

    The mattress is medium in firmness but the top layer is soft so very heavy people may face issues. We recommend utilizing a 100 night trial period. In our review process, we notice an average heavy people are quite comfortable.

  2. Is MOLECULE mattress only for athletes?

    Molecule mattress is a normal mattress and can be used by everyone. MOLECULE has few renowned athletes as brand ambassadors hence the confusion. Molecule’s key selling feature is to fully recover your body during sleep. So any person living an active lifestyle ( like athletes do ) needs proper rest and recovery.

  3. Which MOLECULE mattress is more firm M1 or M2?

    MOLECULE 2 is slightly more firm in feel due to its 5-zone middle layer.

  4. Is it required to flip and rotate the MOLECULE?

    No flipping but yes you need to rotate MOLECULE every 6 months.

Sleep Quality

The proprietary technology, Air Engineered ™, position the mattress as temperature regulating. It optimizes sleep and recovery.  Our experience was inline with brand positioning. You can expect a good quality sleep irrespective of your sleeper type.

Final Thoughts

In our feedback from past customers, we got positive reviews mostly. We got in touch with customer care without disclosing our position as reviewers. We found them quick and helpful.

The OnMOLECULE scored well in firmness, motion transfer, and quality of sleep. The mattresses are competitively priced in their segment.  Overall we are happy with MOLECULE.

We are waiting to review MOLECULE 3 in the next few months when it is launched

Highly recommended!
