Like many customers buying a bed online was not easy and I was also skeptical to buy without touching or trying to sleep on the bed but I did it. I am very happy with my purchased and satisfied with the comfort at a very reasonable price. I love it, I will buy it again for my sister.

So far so good been using for about 2 weeks now. Not too soft not too hard. It's just right for me. It seems to be a little warm but thats to be expected with any foam type mattress. Time will tell but happy so far especially with the price. I like it much better than the 4000 dollar tempurpedic we also have

Overall, I'm pleased with this purchase. This is my first foam mattress. Easier process to get it to my house as opposed to a spring mattress as it was shipped to my house coiled in about a 4.5 foot tall box as opposed to having to go to the store to strap it down on the back of my truck and drive 25 miles. I used my old mattress foundation and it fit that fine. I would say it's between medium and firm, possibly a shade more towards the firm side. When you sit on the side of it, the mattress feels very soft and I sink a bit, however, once you stretch out, it immediately firms up nicely. I'm a very hot natured person. It's not as cool as I thought it may be, but it's no warmer than my old spring mattress on which I have been sleeping the last two plus decades. It is cooler than other foam mattresses and toppers on which I've slept. Summer is a few months away so we'll see how it performs then, although I think it will remain acceptable as we've already had a few hot days and all is well thus far. No discernable chemical smells. Easy set up. It takes a day or two for the mattress to fully expand. This mattress is a bit thicker than my previous one so the sheets are a bit too small.

We've had this great mattress for a couple weeks. It came well packaged and expanded perfectly... no smell. It's great for those who want a firmer memory foam. The description says "firm". In my opinion it's best for those who sleep on their backs and want support. If you have a shoulder or hip issues and sleep on your side... I think a medium or softer mattress would be better. The quality is impressive for the price!

If you are a heavier person (300 Lb plus) DO NOT BOTHER with this or probably any memory foam mattress for that matter. I would sink too much once settled in a spot then it was uncomfortably difficult to roll over to the other side and to get out of bed. The cooling effect lasts all of 5 seconds. The mattress never fully plumped up like in the photo on the website. I literally got up after a few hours and went to sleep in my guest bedroom which has a regular firm mattress on it. I will be returning the mattress ASAP.

I bought this mattress based off the sale price and the fact that it said “cooling” and it doesn't disappoint. We use this mattress in our guest room and everyone raves how great they sleep on it! I'm so happy with this product that I'm going to get another one to change out our master bedroom mattress.

Must admit that I was hesitant about purchasing a mattress in a box, but it was a seamless transaction. PROS: Quick delivery, easy setup, very comfortable, minimal impact when bedmate moves around on their side of the mattress, the Molecule is much lighter in weight compared to the traditional spring mattresses and has handles on the side (which will be super helpful when moving)! CONS: One sinks in a bit when sitting on the edges, could use a little less plastic wrap to be more environmentally friendly...

The best mattress I've ever slept on, best night's sleep ever! And it has the recommendation from my Allergist! It does not allow those microbes to hibernate inside it and grow which contributes to allergies. No more encasing the mattress in plastic or 'water-proof' mattress covers. AND it has cooling technology that is superb; no need to add any toppers, special sheets or mattress covers! Perfect and the best price ever! Love Sam's Club!

I purchased this mattress only a week ago. So far, it is very comfortable. I have not experience any sink into the material. It's cool on the body. It comes with a zip covering. I love the way it was packaged. I would have given the review 5 stars but I ordered a full size and received a Queen size. It took over two weeks and a lot of trouble to arrange for Sams to replaced it!!

This replaced a worn out Casper and I'll stick with Molecule from now on! I plan to buy another one soon. Keep them coming Sam's Club! Comfortable, COOL, beautifully upholstered. Bed was easy to set up and expanded fully within 20 minutes. (YES, I timed it!)
