    Long Overdue Comfort and Relief.

    his mattress was needed badly ! Within 24 hours my aches and body pain were virtually eliminated. I am a side or stomach sleeper depending on where I toss and turn. I felt comfort no matter which angle I laid, which was a testament to the feel of this mattress !The mattress un boxing was so quick and easy . Not too heavy at all. It was ready straight out the plastic , I do suggest letting it sit and air out for 5 minutes initially. I noticed the cooling affect activated almost instantly as I also sweat at night. I was able to enjoy a nice , cool , even temperature rest.

    Happy with this Mattress

    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.

    Firm, comfortable mattress

    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 sleep for warm Summer Nights

    We've all heard about how good copper is for our joints and the textured feel of the mattress contours to my back and shoulder curves, making it an extraordinary night of cooling sleep. If you sleep next to someone who tosses and turns, you won't notice additional movement throughout the night. The handles on both sides of CopperWell make the mattress incredibly easy to carry.
