Comfortable Mattress

[This review was collected as part of a promotion.] This was very easy to unpack and set up right from delivery to setting up in the bed room. It unfolds and inflates quickly. It is so comfortable and soft. I have a very good nights rest when laying on it, like I'm sleeping on a cloud!

No Motion Transfer & No Back Pain

[This review was collected as part of a promotion.] I received the MOLECULE® CopperWELL mattress through The Insiders platform in exchange for my honest opinion. This is my sincere review. The first thing to highlight is how easy it is to move. It comes vacuum-packed in a cardboard box that one person can handle without any problem. It includes opening instructions via a QR code that clearly explains what to do and what to expect when you open the package. In my case, the mattress had no chemical odor or anything unpleasant. It started to "inflate" quickly and fit my bed with no issues. Putting sheets on it is easy. It took about 24 hours to reach a proper level for sleeping on it, although the recommendations say it takes three days to reach its final size. It's very pleasant to sleep on: it feels firm while still contouring to your body. I wake up without back pain. What I love the most is that you can barely feel your sleeping partner move, which is great for uninterrupted sleep. As for temperature, the MOLECULE mattress matches the temperature of the room it's in. Overall, I liked the mattress. I'm satisfied with it and I would recommend it. I think there's room for improvement because MOLECULE® CopperWELL mattresses don't come with a stain- or spill-resistant cover from the factory. However, a point in its favor is that it includes antimicrobial protection.

Great comfort & Support

[This review was collected as part of a promotion.] As a person who weighs over 350 lbs, it is vital that I have a mattress that can support my weight and provide comfort. As a single parent who recently gained custody of two kids, I needed to move back to my parents' house. They were about to purchase curtains for the entire house, but took mercy on us and bought the Molecule Copperwell mattress instead. I am so extremely grateful because not only did they sacrifice, but I am now sleeping so comfortably. To be honest, I didn't have any faith that a rolled-up, vacuum-sealed mattress would be comfortable, and I felt it wouldn't support my large frame. Boy, was I wrong! Not only do I wake up well-rested, but I am not sweating all night. I am being well supported whether I am sleeping on my side, stomach, or back. I can't say enough about how much I am enjoying this mattress. Especially when I saw it rolled up and vacuum sealed. Never did i expect that it would be as comfortable as it is.

Comfortable Night's Sleep

[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.

A Great Night Sleep

[This review was collected as part of a promotion.] I have been in the market for a new mattress for a few months now. Previously we owned an 8 inch box spring mattress so I was a little skeptical when changing to a memory foam mattress. After letting the mattress sit for 24 hours after opening so it fully expands, we placed it on our frame. The first thing we noticed was the much needed change in height. With a thick mattress we could not more easily hop in and out of bed without having to bend too much. The mattress also provides a medium firm amount of support with is great for our backs. Since changing to this mattress we have had great nights of sleep. The only thing I would change about this mattress would be to introduce a cooling laying since it is a little warm and we do live in a warmer climate.

Refreshing. Every. Moment

[This review was collected as part of a promotion.] The CopperWell mattress has changed my experience overnight. The textured feel of the mattress contours to my back and shoulder curves, making it an extraordinary night of R.E.M. sleep. If you sleep next to someone who tosses and turns, you won't notice any movement throughout the night. CopperWell is thick and the layers are beyond effective. The handles on both sides make the mattress incredibly easy to carry. CopperWell has changed the way I will sleep - forever.

Copperwell mattress

[This review was collected as part of a promotion.] I am actually pleasantly surprised by how comfortable this mattress is. It came packaged in a box and you unfold it and let it set up for a bit and fluff up. It formed nicely and easily. The mattress itself is really comfortable and durable. The material is soft, not too lush or too hard to sleep on. I would say overall it's a great choice and would definitely recommend buying another in the future!

comfortably cool

[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.

Molecule 12 inch mattress

[This review was collected as part of a promotion.] This mattress was a pleasant surprise. I really wasn't sure what to expect since I had never heard of this brand before. So far I really enjoy it. It is really comfortable especially if you like firm mattresses. It helped my back and I was able to sleep soundly. I also felt like it let me breathe and kept me cool throughout the night. I would recommend this to anyone who wants a firm good night's rest.
