Molecule 1 Performance Highlights

✅ Pros

  • Pressure Relief: Thanks to zoned support, the hips and shoulders receive extra cushion that melts pressure from the pressure points. 
  • Spine Alignment: Zoned foam delivers exceptional lumbar support and alignment, something that could help people with lower back pain and body aches. 
  • Cooling: One of Molecule’s primary objectives when creating a mattress ideal for recovery was supporting temperature regulation. They succeeded thanks to breathable open-cell foam, gel microbeads, and a cooling mattress cover. 
  • Motion Isolation: The Molecule’s all-foam construction absorbs motion, helping you and your partner sleep soundly. 
  • Off-Gassing: Thanks to the use of carbon filters during manufacturing, this mattress doesn’t have as strong of an odor as the average foam bed. Any slight scent will quickly dissipate, so you can sleep on your new mattress sooner. 

❌ Cons

  • Social impact: Outside of using an eco-friendly manufacturing processes and donating used mattresses, Molecule doesn’t do much in the social responsibility arena. 
  • Unknown weight limit: Without a set weight limit, it’s hard to say how well this mattress supports plus-size sleepers. The average foam mattress is best for light-to-average weight people. 

Cooling

To achieve a good night’s rest, your body must cycle through natural body temperature fluctuations. Some mattresses trap body heat, which stops the body from reaching the lower temperature that it needs for optimal rest and recovery. The Molecule 1 is designed to support these fluctuations in body temperature so you can sleep deeply and not wake up hot and sweaty. 

The top layer and support layer are each designed to optimize airflow, with breathability supporting a cool night’s sleep. And with gel-infused foam, excess body heat is moved away from the body for comfort all night long. The result? An all-foam mattress that helps keep hot sleepers cool. 


Pressure Relief

The Molecule 1 has a comfort layer of soft foam for initial cushion and a zoned transition layer for even weight distribution. Because the foams are designed to cushion the hips, shoulders, and other problem areas while supporting the body’s core, the Molecule 1 boasts the pressure relief that side sleepers need. 


Warranty

Molecule’s infinity warranty covers the buyer from defects for the entire time you own it, whether that’s 10 years or 30. This generous warranty covers indentations greater than 1”, which tells us that the Molecule 1 is built to last. 

 Where is it on the Firmness Scale?

The Molecule 1 is a medium firmness mattress, registering at a 5 on the 1-10 firmness scale. A plush comfort layer hugs the curves while zoned support foam keeps the hips from sinking in too low, delivering a soft yet supportive feel.

What Sleeping Positions Does it Support?

With a softly contouring comfort layer and zoned support second layer, the Molecule 1 balances pressure relief and support in a way that works well for every sleeping position. The zoned support foam eases pressure from the shoulders while ensuring that the body’s core doesn’t sink too low, providing good alignment no matter how you sleep.

Does it Stay Cool?

Molecule took no shortcuts to ensure that they created one of the coolest foam mattresses on the market. Molecule believes that temperature regulation is the key to achieving the deep, restorative sleep that athletes require to feel rejuvenated come morning. With open cell foam, a cooling cover, and gel beads, we recommend the Molecule 1 for hot sleepers.

How Much Weight Can the Mattress Support?

The Molecule 1 mattress doesn’t have any set weight limit. From our experience with all-foam mattresses, we’d recommend this bed for people weighing less than 230 pounds. The medium firmness, all-foam construction, and relatively soft top layer simply don’t offer the firm support required by most heavy people, particular back and stomach sleepers. 

What Bed Frames/Foundations are Compatible?

The Molecule 1 mattress is compatible with any type of supportive foundation. You can even sleep with your Molecule mattress directly on the floor. If you choose a slatted foundation, make sure the slats are no more than 3” apart. If you choose an adjustable base, make sure it’s compatible with a foam mattress.

A Look Inside

The Molecule mattress is constructed from 3 carefully engineered layers of proprietary foam:

  1. Advanced Cover: The cover material combines both heat and moisture-wicking technology to help regulate temperature as you sleep. This works by using a temperature-sensitive polymer that responds to your changing body temperature throughout the night.
  2. RestoreFLO™ Comfort Layer (2”): A soft foam cradles the curves for immediate pressure relief. This layer delivers even more cooling properties with cool gel microbeads and an open-cell structure that supports airflow.
  3. RecoveryFLO™ 3-Zone Response Layer (3”): This recovery layer uses a unique design with a 3D geometric surface. This surface is made of three parts: small diamond zones around the head for soft comfort, large hexagon zones in the center for pressure relief and lumbar support, and more small diamond zoning for softening around the feet. 
  4. ContourFLO™ Support Layer (7”): This proprietary high-density polyfoam provides a supportive foundation for the Molecule mattress. This firm foam layer adds more breathability and promotes healthy spinal alignment.

Unboxing and Setting Up the Mattress

The Molecule mattress comes compressed in a box for easy setup. Simply carry the box to your bedroom, unbox the mattress, and set the still plastic-wrapped mattress on your foundation. Next, remove the plastic wrap and unfold the bed. 

Your new mattress will quickly puff up to life, although it can take up to 72 hours to fully expand. You may notice a slight odor, but it’s unlikely to be strong thanks to the air filtration technology that Molecule uses during mattress manufacturing.

How the Warranty Works

The Molecule 1 mattress has an infinity warranty, meaning you’re covered from defects for the entire time that you own the bed. The warranty covers things like indentations of greater than 1” along the sleeping surface. 

To submit a claim, send an email to support@onmolecule.com with the following information.

  1. Your order number or the first and last name of the person who purchased the mattress.
  2. Description of the defect that you believe to be covered under the warranty. 
  3. A video or photo that clearly shows the defect.

Molecule may take up to 7 business days to get back to you about whether the claim was approved.

Molecule’s Return Policy

You can return your Molecule 1 mattress for a full refund during the 100-night trial period. Just remember that you must wait 30 days, since it takes some time to truly get a sense of how the bed works for you. 

To initiate a return, reach out to Molecule’s customer service team and they’ll help you with next steps. This typically involves a local charity or recycling center picking the mattress up from your home, after which you can expect a refund.  

Should You Buy the Molecule 1?

The Molecule 1 mattress is a recovery-focused bed. Its outstanding cooling technology supports deep, restful sleep that’s beneficial not only for athletes, but hot sleepers, too. With a plush comfort layer and zoned support foam, the Molecule delivers the balance of cushion and support that can help relieve body aches and pains. 

While the Molecule 1 is an excellent mattress, it’s not going to be the perfect fit for everyone. To start, it has a distinctly plush surface and medium feel that may not be firm enough for some people. The average sleeper tends to prefer a medium-firm mattress like the Casper memory foam bed.

Additionally, with its all-foam design, we don’t recommend the Molecule 1 for most plus-size people. For a mattress better at supporting bigger bodies, head over to our Big Fig Mattress Review page.

The Molecule vs Other Bed-In-a-Box Mattresses

The Molecule 1 is an all-foam mattress with a price point that falls just below the typical online mattress. While most bed-in-a-box mattresses are foam or foam hybrid beds, there are some ways that the Molecule 1 stands out. To start, this bed is cooler than most, making it better for hot sleepers. In addition, its zoned foam transition layer marries contouring cushion with reliable support, great for body aches and pains. 

However, the medium firmness and all-foam construction aren’t as supportive as some online mattresses, especially hybrid beds. As a result, it may not be as good of a fit for plus-size people.

The Molecule 1 vs The Molecule 2

Molecule manufactures two all-foam mattresses: the Molecule 1 and the Molecule 2. You can think of the Molecule 2 as an upgraded version of the Molecule 1. Both beds are engineered for recovery by supporting the body’s natural temperature fluctuations. However, the Molecule 2 has a few upgrades. 

First, it has a BioCharge recovery layer that’s engineered to boost circulation and enhance cellular function. Molecule claims that this layer offers even more recovery support than the original Molecule 1. In addition, the zoned layer of the Molecule 2 has five zones instead of the three found in the Molecule 1, offering superior body weight distribution.

Molecule 1 FAQs

Can I try the Molecule 1 mattress in a physical store?

No, you cannot find Molecule mattresses at brick-and-mortar retail locations. Molecule is a direct-to-consumer mattress brand, which means they sell their products directly to you. By skipping the showroom, Molecule is able to sell their beds at competitive prices. Plus, you can try this mattress risk-free in your home thanks to their 100-night sleep trial.

Should I use a mattress protector over my Molecule 1 mattress?

A waterproof mattress protector is the only way to safeguard your mattress from spills or other accidents. However, Molecule cautions that some of these protectors can negatively impact the cooling properties of the Molecule 1. Use your best judgement on what works best for your sleeping experience and mattress protection.

Is the Molecule 1 more eco-friendly than other all-foam beds?

All Molecule mattresses are better for the environment than the average foam mattress. This is thanks to a variable pressure foaming manufacturing process that utilizes carbon filters and an air-sealed chamber to reduce emissions. They also use only CertiPUR-US certified foams, ensuring their beds are made without harmful chemicals like VOCs or heavy metals.
