My sleep has improved so much since I bought this mattress. The firmness is great and is very comfortable. Highly recommend buying this mattress to anyone with back or neck problems. It might take you a while to adjust once you buy it but you get used to the texture.

I have an injury that has made sleeping and finding the right mattress very difficult. With the number of professional athletes promoting this brand and the promise of restorative sleep, I had high hopes. Unfortunately, this is one of the the most uncomfortable mattresses I have ever slept on. It's so hard, I don't know how it could be restorative for anyone. My injury got significantly worse during the required 30 night trial, and I'm currently sleeping on an air mattress because it is the better option. Can't wait to get this thing out of here so I can get something else. FYI: While everyone in customer service is really nice, returns/refunds are not as quick/simple as they make them sound.

Perfect! Not hot like most memory foam. Not too firm not too soft. Can’t even feel movement from animals or my partner. Immediately started to inflate and didn’t take long to finish slept on it the same night. No strong chemical smell. I’ve had multiple memory foam mattresses and toppers and this is definitely the best!

This mattress is amazing. I was previously sleeping on a cheap spring mattress with a generic 2 inch memory foam topper. It was the only thing I could afford years ago. Up until my Molecule 1 mattress arrived, I was always sore and stuff when I woke up in the morning. I figured it had to be the mattress as I'm only 34 and shouldn't be experiencing such aches and pains due to age just yet. The first few nights were somewhat difficult as the Molecule 1 was definitely more supportive and unfamiliar to me. But after that it was great. No longer am I tossing and turning more than 20x per night. I am sleeping deeply, with only a few position changes during the night. My dog is also sleeping better, and rarely moves now during the night or day. I did research other similar mattresses, but what drew me to the Molecule was the science and then the professional athlete reviews. The only issue I had was finding out that I'm sensitive to tencel, and therefore the free queen sheet set was useless to me. I contacted customer service to exchange it for a full size (so at least my mom could use it and she was in need of a new sheet set anyways). Not only did they ship out a full sized set, but they told me to give away or donate the queen sized set. No need to send it back. I just checked in with my aunt and she is very pleased with the queen sized set! My mom is happy with the full sized set and it is even holding up to my dog doing his digging/scratching routine before laying down. Overall I would recommend this company and products. I'll definitely be back in the future.

[This review was collected as part of a promotion.] My wife doesn’t sleep well and this bed has helped a bunch. Also, my sciatic has been hurting for over a year and this bed has given me days of no pain that I have not had in a long time. Highly recommend! Not too soft, not too firm, just right.

I love my mattress! Feels so comfortable , stays cool while I sleep.

Bed says medium but it’s actually really firm. Too hard for me.

Happy with my purchase the mattress is very comfortable!

So comfortable! Better than the tempurpedic I just bought.

This mattress is outstanding!!! My bed is now the most comfortable bed to sleep on 🥰
