What is the Molecule Mattress Topper?

Developed by a team of expert engineers in collaboration with top neurologists and sleep experts, the Molecule mattress toppers have been designed to maximize rest and recovery for those living active lifestyles. But you don’t have to be an athlete to reap the benefits of these high quality sleep essentials—everyone can benefit from their superior pressure point relief and temperature regulation.

Here’s an overview of the three models available:


  1. CopperWELL™

    This popular pick features copper-infused memory foam with an open-cell structure for maximum breathability and heat transfer. It includes a proprietary seven-zone surface technology, which delivers dynamic and targeted support to each part of your body as you sleep. 
  2. Triple Zone PRO

    This is Molecule’s Air-Engineered mattress topper, which basically means it harnesses airflow to keep you sleeping cooler and deeper. It includes an advanced cool-to-the-touch zoned cover with an antimicrobial treatment, which protects against bacteria, mold, odors and other degradation due to microbial growth. It’s been meticulously designed to relieve pressure on your joints when you sleep, so you’ll always wake up feeling light and pain-free. 
  3. ArcticZONE

    Molecule’s newest topper to hit the sleep scene, this is a soft, cooling, gel-infused topper. Like the CopperWELL, it includes a seven-zone surface technology, which enables increased airflow and targeted support from head to toe. It also includes a cool-to-the-touch cover with an antimicrobial treatment, which protects against bacteria, mold, odors and other degradation due to microbial growth. 

How Does It Work?

Molecule’s mattress toppers are designed to add an extra layer of comfort to your sleep experience. While each model comes with its own instructions, most are intended to be placed on top of your mattress and under your sheets.

What are the benefits?

All of the Molecule mattress toppers were made to maximize support and comfort—for the best recovery-focused sleep. While each model delivers its own unique benefits, all three provide:

  • Superior pressure point relief from head to toe
  • Full body support for every type of sleeper
  • Optimal air flow and breathability 
  • Unparalleled temperature regulation

The Triple Zone PRO and ArcticZONE models also include added protection against bacteria, mold, odors and other microbial growth, thanks to an antimicrobial treatment that’s been incorporated into their covers (the CopperWELL does not include a cover).

Molecule Mattress Topper Construction

With equal emphasis on pressure point relief and temperature regulation, every Molecule mattress topper was designed with comfort and support in mind. Each is three inches thick and made with CertiPUR-US® open cell memory foam, which provides the perfect amount of cushion and helps move heat away from your body.

Here’s a closer look at what comprises each Molecule mattress topper: 

  1. CopperWELL:
  • Three inches of copper-infused memory foam with proprietary seven-zone surface technology that provides dynamic, targeted support from head to toe, and actively dissipates heat.
  1. Triple Zone PRO: 
  • Two layers of gel-infused memory foam for optimal pressure relief and temperature regulation.
  • Cool-to-the-touch polyester cover with antimicrobial treatment to protect against bacteria, fungus, mold, mildew, odors and degradation due to microbial growth.
  1. ArcticZONE:
  • Three inches of gel microbe-infused memory foam with proprietary seven-zone surface technology to provide pressure point relief, targeted support and cooling.
  • Cool-to-the-touch polyester cover with antimicrobial treatment to protect against bacteria, fungus, mold, mildew, odors and degradation due to microbial growth.

Molecule Mattress Topper Size and Dimensions

The CopperWELL and Triple Zone PRO toppers are available in six different sizes; the ArcticZONE model is available in queen and king sizes.

Here’s a look at the dimensions:

  • Twin (75”L x 38W x 3”H; 14 pounds)
  • Twin XL (80”L X 38″W X 3”H; 15 pounds)
  • Full (75”L X 53″W X 3″H 20; pounds)
  • Queen (80”L X 60″W X 3”H; 24 pounds)
  • King (80”L X 76″W X 3”H; 31 pounds)
  • California King (84”L X 72″W X 3”H; 31 pounds)

Molecule Mattress Topper Firmness

All three of Molecule’s mattress toppers are considered medium-plush, but there are some key differences in how each feels:

  • The Triple Zone Pro emphasizes pressure point relief and weight distribution.
  • The ArcticZONE is a softer, cooling gel infused topper so it provides sinking support with more cooling aspects.
  • The CopperWell is similar to the ArcticZone, but without the cooling gel infusions, so it’s a little more firm and provides more of an uplifting support.

Molecule Mattress Topper Performance

Now that we know what the topper is and how it’s made, let’s take a closer look at its performance across a few key ares:

Motion isolation: All of the toppers do an excellent job of isolating motion. This means that if your partner moves around at night, you likely won’t be disturbed.

Pressure relief: Molecule’s toppers provide excellent pressure point relief. The CopperWELL and the ArcticZONE models both include a proprietary seven-zone technology that provides targeted support and pressure point relief for each area of the body. The Triple Zone PRO topper has been shown to significantly improve your current mattress by reducing existing mattress pressure points as well.

Temperature control: All three models were designed to keep you cool and comfortable all night long. If you prefer a cool sleep experience, the ArcticZONE is your best bet—this model is the strongest cooling topper Molecule offers.

Support: All of the toppers include three inches of body-cradling foam, which keeps your spine aligned and prevents sagging. The CopperWELL and ArcticZONE models both include a seven-zone targeted support technology, so each part of your body is cradled and your spine is supported. Of the three models, the CopperWELL provides the most uplifting support.

Conforming: The toppers are all made of foam so they contour to your body, creating the perfect balance of cushion and support. Since the ArcticZONE is a gel infused topper, it provides more of a sinking support which means it will conform to your body slightly more than the other models.

Ease of movement: All of the toppers are easy to move around on so you never have to worry about feeling stuck in one position all night.

Durability: Like all of Molecule’s sleep essentials, the toppers are made of premium materials and thoughtfully constructed, which means they were built to last. Each comes with a five-year warranty, so if you notice any degradation prior to the five year mark, you can simply reach out to a customer service representative for assistance with a fix or a replacement.

Sex: The topper is a great option for couples. It is plush-firm, so it has some give but isn’t overly bouncy. Plus, it won’t make noise when you move around.

Off-gassing: Molecule leverages a patented technology called Variable Pressure Foaming, which not only reduces emissions by 97 percent compared to standsard manufacturing, it also helps to remove off-gassing and the need to “air-out” the toppers prior to use.

Molecule Mattress Topper Cleaning and Care

The Molecule mattress toppers are easy to care for. You can simply wipe them with a soft cloth or sponge using a mild soap that is diluted with lukewarm water. Machine wash the covers in cold water on delicate cycle and lay them flat to dry. Never machine dry the covers—hang or line dry only. 


The Triple Zone PRO and ArcticZONE models both include covers with a MOLECULEshield™ antimicrobial treatment that protects against common allergens like bacteria, mold, odors and other degradation due to microbial growth, providing a clean sleep experience.

Molecule Mattress Topper versus the Competition

When it comes to mattress toppers, there are many different brands to choose from. Here’s a look at how Molecule’s models compares to those of another leading brand:

Molecule Mattress Topper vs Tempurpedic

Like Molecule’s mattress toppers, Tempurpedic’s toppers are designed to provide a comfortable and restorative sleep experience. But there are a few key differences between them. The first is the number of products available—Molecule offers three models to choose from; Tempurpedic offers two. Another key difference lies in the way the brands approach pressure point relief. While both Molecule and Tempurpedic prioritize pressure point relief, only Molecule uses a seven-zone approach to provide targeted support from head to toe. This provides the right amount of support for each part of your body and ensures your spine stays in proper alignment as you sleep. Another difference lies in the thickness of the toppers. All of Molecule’s models are three inches thick; Tempurpedic offers a three-inch and a less expensive, two-inch option. Still, even if you opt for the less expensive model, depending on the size of your bed, Tempurpedic’s toppers will likely cost you more than Molecule’s. Speaking of price—all of Molecule’s models are built to maximize cooling and temperature regulation. If you want the premium cooling experience from Tempurpedic’s toppers, you’ll have to pay extra to upgrade your topper to their cooling fabric. And finally, Tempurpedic’s return policy is not nearly as forgiving—while Molecule accepts returns within 30 nights of your delivery date, Tempurpedic only accepts returns if the item was damaged at delivery or if there is a product defect.
