MOLECULE CopperWELL 12" Gel Memory Foam Mattress

Instructions

<p>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.</p> <h2>Cooling Copper</h2> <p>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.</p> <h2>Triple Layer Design</h2> <p>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.</p> <h2>Rest Assured</h2> <p>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.</p> <h2>Frequently Asked Questions</h2> <ul>  <li><strong>Can this mattress be used on an adjustable base?</strong> Yes, the MOLECULE CopperWELL® 12" Mattress can be used on an adjustable base, platform bed, or any box spring.</li>  <li><strong>How is this mattress delivered to my home?</strong> The MOLECULE 12-Inch CopperWELL® Mattress is packed for easy carry and setup. The mattress is delivered to your home in a box so all you need to do is unpack, unroll, and unwind. It is recommended to let your mattress fully expand for 48 hours to regain its shape, but it can be used as soon as it looks comfortable.</li>  <li><strong>What is the weight limit for this mattress?</strong> The weight limit is 300 pounds per side.</li> </ul>

I love it cause I’ve slept on it last night and made me sleep much better than I had In years

walmart.com

My son loves his new CopperWELL Medium Gel Memory Foam 12" Twin Mattress. It's soft but supportive, and you don't sink into it. The price is great, and there was no strong smell after opening. He's been sleeping really well on it. We definitely recommend and would purchase again.

Great mattress

ashleyfurniture

Very comfortable, only wish they rolled opposite direction because center has a bit of a dip in the middle still waiting for it to come out. Would suggest using a solid frame or something if not using a box frame. Had to engineer a base due to bed frame I ordered with it had slats and not as many as needed.

Overall great bed

Great mattress!  We downsized from a KING mattress to a QUEEN and this one is wonderful.  I love the cooling gel version and would definitely recommend!

PLEASANTLY SURPRISED!

this has to be the best mattress I have owned in a very long time. It is comfortable, I like cooling layer, I have slept so much better.

great matress

Thanks for the fast service and the Mattress is awesome, not 2 mention I sleep through the night without Waking up...

Dream Land...

Bought for my teenage daughters, great size and comfort both said. Box came in via Fed Ex and was fully expanded within 12 hours. Great purchase for the price.

Excellent investment

It's perfect in imop. It's not too hard or too soft. I can sleep sideways or on my back. I recommend it to my son and he just bought one after testing it.

CopperWELL Medium Gel Memory Foam Mattress

So comfortable, I don't know why it took me so long to get one. I love it.

Next Level Comfort

Bed says medium but it’s actually really firm. Too hard for me.

It’s firm not medium

My bed is currently on the floor because the product was not manufactured properly. There are gaps, holes half drilled or no holes drilled at all!!!!
