About this item

Product details

Improve the quality of your sleep with cooling comfort and adaptive support on the MOLECULE CopperWELL® 12" Gel Memory Foam Mattress. A cool-to-touch cover helps you unwind from the moment you lie down. It features MOLECULEshield™ antimicrobial mattress protection for lasting freshness. CopperWELL® copper-infused gel memory foam provides the perfect blend of personalized pressure relief and active heat transfer. Its open-cell foam structure enhances breathability while copper pulls away heat to help provide an ideal sleep temperature. The pressure-relieving properties help to prevent tossing and turning, promoting longer periods of undisturbed sleep. Memory foam delivers ample support in key pressure point areas, gently pushing back to the places that need extra uplift. Triple-zoned RecoveryFLO® targeted support foam adds more uplift where you need it and less where you don’t, which helps keep your body in proper spinal alignment for more restorative rest. Underneath, ContourFLO™ maximum support foam ensures lasting durability and structural stability for years of soothing sleep.

Cooling Copper

The CopperWELL® Mattress features gel memory foam infused with real copper, which pulls heat away from your body to promote longer periods of restorative rest. Combined with a MOLECULEshield™ cool cover that protects against bacteria, fungus, mold, mildew, odors, and degradation due to microbial growth, your sleep space will feel reliably refreshing for full-body recovery.

Triple Layer Design

This mattress includes three layers of personalized comfort and zoned support, starting with 2 inches of CopperWELL® copper-infused gel memory foam. Next, 2 inches of 3-zone RecoveryFLO® support foam deliver a blend of pressure relief and targeted alignment. At the base, an 8-inch layer of ContourFLO™ base foam ensures structural stability for years to come.

Rest Assured

All foam used in MOLECULE mattresses is manufactured to the strictest environmental standards. They use a patented technology called variable pressure foaming that uses an air-sealed chamber and carbon beds to scrub harmful emissions by 97% compared to standard manufacturing. The foams used in this MOLECULE mattress are CertiPUR-US® certified and made in the USA.

I Actually Love This Mattress

[This review was collected as part of a promotion.] I’ve never really cared about mattresses, but I actually love this one. It’s soft but still supports my back, stays cool all night, and I finally sleep through without tossing and turning. I wake up way more rested than I used to. If you’re thinking about getting a new one, just do it. This thing made a real difference for me.

Very Firm

[This review was collected as part of a promotion.] This mattress is not for those who like the feel of a pillowtop mattress. It is very firm and supports the body well. It is cool to the touch and the material feels silky. I have enjoyed many nights sleep on this mattress and prefer it to my old mattress, which is fairly new.

Rest, Recover, Refresh: Molecule CopperWELL

[This review was collected as part of a promotion.] I been using this Molecule CopperWELL 12 inch queen mattress for a few weeks now and honestly it really helped my sleep. After a long day of work and running around with the family, my back usually hurts a lot but this bed gives good support. The top part has this copper gel stuff that actually stays cool so I don't wake up sweating in the middle of the night like my old bed. It also has different support zones so your hips don't sink in too deep and your shoulders feel comfortable whether you sleep on your back or side. The bottom layer is super solid and sturdy so the mattress doesn't feel cheap or flimsy at all. Overall it fits my busy daily routine great because I get way better rest now and wake up feeling refreshed without feeling sore. Definitely a great mattress if you need something comfortable for everyday recover.
