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.

Medium Firm Performance

[This review was collected as part of a promotion.] When I think of mattresses that come in a box, I immediately cringe. I picture super soft foam core mattresses that offer little no support and have to be replaced long before my wallet is ready for it. Needless to say, I was skeptical when we received this mattress..in a box. This bed will primarily be used by my teenage step-son (and a few guests) and we needed to make sure that the quality was high enough to be able to withstand everything that he'll definitely throw at it. The mattress was easy to transport to the bedroom where it will live and even easier to set up. It didn't take long to resurrect to its full size and become usable. The firmness level is medium but it still feels like the material is adjusting to your weight which is what I'd expect from a foam mattress, except without feeling like you're sinking into it. It works well with standard depth sheets and the sleeping experience has been great so far. I've felt like the pressure that I usually feel on my back isn't there and the mattress doesn't seem to retain heat. Overall, for a side sleeper, this is a great, reasonably priced option that I have high hopes will be durable enough to last for many years.

Comfortable and cushy

[This review was collected as part of a promotion.] I have always had a traditional spring type mattress so I had really no idea what to expect. After unwrapping and letting it expand on its own I was amazed at how comfortable it was. It’s supportive and cushy in ways my traditional mattress never was. It is quite thick but getting sheet around it is pretty easy. I needed some help to unpack it from the box due to its weight but otherwise it was easy to handle.

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!
