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.

Peaceful Sleep

[This review was collected as part of a promotion.] I could not be happier with this mattress. The material molds comfortable around pressure points like shoulders and hips while still giving proper support where it is needed most. It honestly feels like sleeping in a high-end luxury hotel room every night. Another huge benefit for anyone sharing a bed is the impressive motion isolation. Movement on one side of the bed stays completely quiet and undisturbed on the other. It expands quickly after it provides deep sleep, restorative sleep and has exceeded all of my experience for comfort and durability.

Best sleep I have had in a long time!!

[This review was collected as part of a promotion.] This mattress is AMAZING!! It came rolled up right in a plastic bag and plastic wrap and packed in a box. After unpacking it inflated quickly and was true to size. It smelled fresh and clean and after sleeping on it for a week I can say I have had the best sleep I have had in a long time!! I love how it is cushioned like a memory foam mattress but not too much. It is easy to move around and it holds it's firmness to the eye of the mattress. I used to get sore shoulders on my old memory foam mattress because I sleep on my side. I can still sleep on my side with this mattress and I am not getting the pain I used to get. I had also upgraded from a full size bed to a queen size and the larger size helped as well. Highly recommend this mattress to anyone looking to improve their sleep and comfort.

Supportive and Comfy

[This review was collected as part of a promotion.] I've been sleeping on the MOLECULE CopperWELL® 12" Mattress and honestly, I'm really happy with it. It hits that sweet spot of being nice and firm while still feeling super comfortable because it contours right to my body and definitely feels more supportive than a traditional coil mattress. As for the cooling feature, I didn't really notice much of a difference, but to be fair, I sleep with a waterproof mattress pad on it, which probably blocked some of that effect anyway. Getting it inside was a bit of a workout since the box is pretty heavy to move around by yourself, but with a little determination, it was totally doable. I do love that the cover has an antimicrobial treatment to keep things fresh, and knowing the foam is CertiPUR-US® certified gives me peace of mind since I might end up handing it down to my kid. Overall I would recommend it!
