[This review was collected as part of a promotion.] I honestly wish I had bought this mattress years ago. I've had it for weeks now, and it's been comfortable. We're a mix of tall, larger adults and shorter, smaller people, and it works well for us. We also have both a side and back sleeper and neither of us has had any complaints. It's comfortable without being too soft. It has just the right amount of firmness to feel supportive, and the 12" thickness feels substantial without being overly bulky.--And 12" mattresses are easier to buy fitted sheets that fit. One thing I would mention is that the base matters. We use a wooden slat foundation with slats about 3" apart, which is what the manufacturer recommends. Besides giving the mattress the support it needs, using the right foundation also helps avoid warranty issues (per the information from Molecule). I'm planning to buy another one for our guest room because it's been such a good all-around mattress. It's definitely one of those purchases that makes you wonder why you waited so long.

[This review was collected as part of a promotion.] This campaign couldn't have come at a better time. I just moved into a new apartment this past week and I knew I would need a bed. This bed is the best I've ever had. I was sceptical at first because I am a guy who likes the plush feel and I knew it wa supposed to be medium firm. However, the Molecule Copperwell is built in a way where it feels plush and firm at the same time. And once you lay down, you feel at rest immediately! I would recommend this to anyone 12/10.

[This review was collected as part of a promotion.] Feels like you sleeping on wrapped up snuggly clouds. I instantly feel asleep and sleep through out the night, my body temperature did not change stayed comfortable all night, no tossing and turning woke up feeling refreshed with plenty of energy and no back pain. With my previous mattress I would wake up with soreness on my hips and back, with the Molecule I wake up without soreness or stiffness. After having the mattress for a while I don't feel my body temperature is as regulated as the first couple of nights sleeping on it. I would recommend buying the Molecule CopperWell if you like a sort of firm mattress with memory form.

[This review was collected as part of a promotion.] Foam mattresses have come a long way. I have always been a traditional (innerspring) mattress person, but have had the opportunity to experience this MOLECULE CopperWELL 12" mattress. Just like a majority of modern mattresses, this mattress ships in a vacuum-sealed bag rolled up into a box. Setup is pretty straightforward: unroll the mattress, cut open the bag, allow the mattress to expand. I currently sleep on a "very firm" innerspring mattress so I wanted something that felt similar. My initial impressions of the mattress, after waiting 24 hours, is that the "medium firm" is just right for me. While I have only slept on the mattress for one night so far, I was able to sleep perfectly fine and look forward to evaluating it more over time. The first layer of foam is advertised as the CopperWELL layer with "gel [that] relieves pressure while helping heat move away from your mattress". While I typically sleep hot, I did not notice any additional "breathability" that this layer may have offered over my usual mattress - this is not a bad thing. Taking a look at the actual layers, you can see brown-colored bits embedded into the first-layer foam which I'm assuming is the CopperWELL gel. I think the idea behind the marketing is that copper is very conductive and has the ability to move heat efficiently, however, the heat has to actually go somewhere which I'm not certain these little bits can accomplish effectively. Overall, this mattress works well for my needs and I look forward to more nights to see if my sleep improves. The one thing that kept this from a 5-star perfect review for me is that after the mattress fully expanded, the cover was shifted off center. I don't know if this is because of the vacuum process or if it was misaligned before packing. Either way, it is nearly impossible to adjust the cover and likely requires it to be fully removed and put back on.

[This review was collected as part of a promotion.] After unboxing the mattress it took no time to set into its shape. It's been about a week & this has been some of the best nights sleep I've had in years. The mattress is soft, it feels like I'm sleeping on a cloud. Its cooling temperature keeps my body temperature regulated so I'm no longer sweating in my sleep. With my old mattress I would toss and turn and I always woke up with back pain. Sleeping on this mattress I can wake up on my back or my side and my full body feels great. I feel more well rested & ready to start my day. I love this mattress & my kids love it too. This mattress gives meaning to the phrase "sleeping like a baby" because that's exactly what me my toddler have been doing. I would definitely recommend this mattress.

[This review was collected as part of a promotion.] I've been sleeping on the CopperWELL® 12" Mattress for a while now, and it's been a great upgrade. It has a nice balance of softness and support, so I don't feel like I'm sinking in, but it's still comfortable enough to relieve pressure on my shoulders and hips. I also noticed that it stays fairly cool throughout the night, which has made sleeping much more comfortable. The mattress arrived well packaged, expanded quickly, and didn't have a strong odor. Overall, it offers excellent comfort and quality for the price, and I'd definitely recommend it to anyone looking for a supportive and comfortable 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!

[This review was collected as part of a promotion.] I've had the queen-size Molecule CopperWELL 12" mattress for a while now, and it's been great. It's soft enough to be comfortable but still supportive, so I don't wake up with a sore back or stiff shoulders anymore. One of my favorite things is that it doesn't transfer much movement. If my partner gets up during the night, I barely notice. Setup was easy—it expanded pretty quickly after opening, and there wasn't much off gassing (which is better than my previous experiences with foam mattresses). Overall, I've been sleeping better since switching to this mattress. I'd definitely recommend it if you're looking for a 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.

[This review was collected as part of a promotion.] Initially, I was skeptical because THE ENTIRE MATTRESS CAME IN A BOX that was definitely not queen-sized, so that blew me away a bit. I wasn't sure what to think. Haha. The very first time I laid on it, I fell in love immediately! I had never experienced a hybrid mattress before—only traditional spring mattresses. It has the perfect balance of soft versus firm, and it's cool to the touch. A lot of times my kids come into my bed at night, and I noticed the bed barely moved as they “snuck” in, versus the bed shaking violently. I've also been waking up feeling much more refreshed than usual. Definitely worth the change. Sleep changing → life changing! One thing I wasn't aware of initially is that this type of hybrid mattress needs either a platform base or a frame with slats that are close together, so definitely keep that in mind when purchasing.
