Super Impressive Mattress

[This review was collected as part of a promotion.] We are super elated that we finally made the decision to get a Molecule CopperWELL mattress. It was crazy simple and fast to set it up right out of the box; it was ready for a nighttime customer in just a few short hours. It's considerably lighter than an innerspring mattress, so it has a much less chance of having any sagging in 10 years. I am a side sleeper and it gives me great support. During the hottest parts of the year like now, their cooling technology is noticed and appreciated. This is absolutely an economical option because it's just as good as other more well known brands. So glad we got one!

Firm, comfortable mattress

[This review was collected as part of a promotion.] I was super excited when I found out that I was selected to participate in this campaign, as my husband and I were in sore need of updating our mattress. I like the comfort of memory foam, but find it too soft without enough support and very hot to sleep on, so I was intrigued by the promises of the molecule mattress to provide support while also being cooling. It arrived in a large box which was quite heavy, it took both my husband and I to be able to carry it upstairs. It was vacuum sealed, but expanded quickly once opened, probably took about 15 minutes or so. I wanted to wait a month or so before writing my review so that I could thoroughly evaluate my opinion on the Copperwell 12” mattress. I have to say that it is really comfortable and conforms to your body contour without feeling too stiff, it definitely has a firm feel to it however. It is also pleasantly cool to sleep on, and doesn't seem to generate the same amount of heat as traditional memory foam. Overall I was pleasantly surprised with this mattress and would recommend it if looking to purchase a new mattress.

Cool and Comfortable

[This review was collected as part of a promotion.] This mattress from Molecule is great. I'm always a little skeptical of the mattresses in boxes but once it was unwrapped and full size, it was pleasantly comfy. It's firm but still soft and forming. I love the cooling effect it provides, as I'm a hot sleeper.

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.

Comfy Mattress

[This review was collected as part of a promotion.] I love my new CopperWell 12" mattress. I have slept on other memory foam mattresses before and they always retain body heat and make sleeping an uncomfortable challenge. The CopperWell mattress sleeps much cooler (which I love) which means less tossing and turning and a much better overall night of sleep. I will be enjoying the mattress for a long time.

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.

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.

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.

Cooling effect

[This review was collected as part of a promotion.] I found the CopperWELL12 to be a good night's sleep. The mattress is firmer than what I typically have slept on in the past. It did take some getting used to but overall is a great night's sleep. I would recommend this mattress to anyone. It arrived in a box that was a little heavy to get up the stairs on my own. Once unpacked it was cool to watch it inflate. I did wait the full 48 hours to sleep on the mattress, and it filled out nicely. This will be used in a guest bedroom, but I am confident our guests will get a great night's sleep.
