Description
Improve your sleep quality, recover faster, and prevent the growth of damaging bacteria and fungus with the MOLECULE CopperWELL™ Mattress.

Cooler, More Comfortable Sleep Every Night
[This review was collected as part of a promotion.] After sleeping on the CopperWELL® Queen Mattress for several weeks, I've been really happy with the overall experience. The first thing I noticed was how supportive it felt without being overly firm. It has a comfortable balance of cushioning and support that helps relieve pressure around my shoulders and hips while still keeping my spine aligned. I also appreciated that the mattress doesn't trap heat the way some memory foam mattresses can. The copper infused foam and breathable construction seem to help regulate temperature, making it much more comfortable throughout the night. I wake up feeling more rested and don't find myself constantly adjusting to get comfortable. Another feature I value is the quality of the materials. Knowing it's made without fiberglass and uses CertiPUR US certified foam gave me additional confidence in the purchase. Setup was straightforward, and the mattress expanded quickly after unboxing. If you're looking for a memory foam mattress that combines pressure relief, good support, and a cooler sleeping experience, I think the CopperWELL® Mattress is an excellent option. It's been a worthwhile upgrade, and I'm very satisfied with how well it's performed.

Copperwell 12 Mattress
[This review was collected as part of a promotion.] I have been sleeping on the Molecule Copperwell Mattress for a little while now , and I’m really happy with it . It has a great balance of comfort and support , so I wake up with less back stiffness than before. The cooling feature actually helps keep me from getting too hot during the night , which has made a noticeable difference in my sleep. The mattress feels well made and holds its shape nicely. It took a couple of nights to get used to it , but now I sleep much better. Overall . I’m very satisfied with this purchase and would definitely recommend it.

Super easy and comfy
[This review was collected as part of a promotion.] I was nervous to buy a mattress in a box but set up was so easy. I took it out of the box and plastic and put it on my bed frame. Says it takes 24 hours to fully puff up but even after like 2 minutes it was soft and plush. I can really tell the cooling factor which is awesome and much appreciated. I like the simplicity and how it’s spring free but still supports me. Also sounds silly but my bedsheet stays on way better than on my old bed.

Blissful nights sleep
[This review was collected as part of a promotion.] I wanted to share an update regarding our recent home improvement decision. We spent a few weeks trying to decide whether to replace the guest room mattress or buy new curtains for the house, and we ultimately decided to replace the mattress. It turns out it was a great choice. Our son now has full custody of his new baby boy and needed to move back home for support. He has slept on both the old mattress and this new one, so he has a great point of comparison. The delivery was timed perfectly. After opening the box and placing the mattress in its spot, he left for a weekend vacation. In no time, the mattress was fully settled with zero traces that it had been vacuum sealed. We decided to test it out ourselves and found that not only is it comfortable, but it is also like sleeping on a cloud without being soft and squishy. It is firm and able to comfortably support our 325lb son. After his first night using it, he mentioned that he couldn't remember the last time he slept through the night without waking up numerous times. He initially thought it was a one-off experience, but he has reported the same great results each night thus far. It seems we definitely made the right choice.

Good mattress
This mattress is awesome! Well we haven't slept on quite yet we love laying on it. It's my daughters first big girl bad and she's not officially moved out onto it yet but it's going to definitely do the trick! I'm not sure what it'll feel like after a couple years but it was definitely worth the price for now especially for a two year-old.

Great mattress
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.

Overall great bed
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.

CopperWELL Medium Gel Memory Foam Mattress
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.
