[This review was collected as part of a promotion.] This Molecule mattress offers the soft, gentle feel I need when I plop down on the sheets. I feel myself come to a comfortable rest after sinking gently through the top layer. I feel cool when I sleep on this mattress, and it doesn't bounce or make noise when my wife needs to exit or enter the bed. I normally sleep on my side, but I do frequently toss and turn. My wife hasn't complained about me waking her up, so it passes that test. This mattress has a transition layer that draws heat away from me when I sleep. I needed this feature. I received this mattress for a discount in return for my honest review.

[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 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.

[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.

[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.

[This review was collected as part of a promotion.] The Molecule Copperwell 12 inch mattress was installed in our 10 year old son's room and he loves his new mattress. I slept on it for a few days to try it out and I had a great experience as well. The medium plush feel of the mattress makes you feel that it is hugging you in place. Despite the mattress not neesing a foundation, it procides excellent support. The edge support has been great as well. The packaging was excellent. I used the included utility to cut the plastic wrap open, but in my hastiness, I went into the outer cloth a little. It was my mistake. The foam expanded within a couple of hours to an usable state. We let it air out for a couple of days even though we didnt get any chemical smell, right out of the box. The edges were not completely wrinkle free but it feels like it inflated to its full size. It fits a queen bed without any issues. The cloth material feels cool to touch, but it didnt feel cold for the entire night. Overall, its an excellent product from Molecule. Would recommend it for sure.

[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.

[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.

[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.
