I have a Molecule 1 California King Mattress and it is unbelievable! It is so comfortable and cool! I am a hot sleeper and as I have been sleeping on my Molecule mattress, I rarely wake up at night. Most nights, I wake up and my bed is practically made since I barely moved during the night. It is amazing! I have slept in 5-star hotels for the last 10 years and this bed is better than any bed I have slept in. I love it and would definitely recommend it to anyone looking to invest in their night's sleep!

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.

I really love how soft and cooling this mattress is. It is the best mattress I have ever bought and have slept extremely well every night since it has arrived. I've never experienced any mattress like this! I love Molecule and the quality and would recommend this company to anyone!

[This review was collected as part of a promotion.] If you’re looking for a more firm mattress, then this is it. Howard, this mattress did not work for us as it is too firm for hips and shoulders, and does not sink in to provide enough spinal support. Our hips and back hurt after sleeping on this mattress.

[This review was collected as part of a promotion.] This is my third Molecule Mattress purchase. The mattress is GREAT however I ordered incorrectly. I selected California King not knowing It was much longer than standard King. It does not fit on my bed set.

I ordered this mattress, king size, after many months of reviewing mattresses in a box. I am so glad that I did! The price was right and I got a set of their percale sheets with my purchase! The sheets are amazing by the way. I got the mattress quicker than I expected and it inflated all the way almost immediately! I went to change the sheets, after the first week of getting the mattress, and noticed 3 small tears on the top. I chatted with a representative online and he put an order in to have the top sent to me at no charge! It came within a few days as well. Very happy with my purchase and this company!

[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 am grateful to the Molecule team for providing a high-quality mattress at an affordable rate for a grad student! Sleep is of the essence and gives me an immediate advantage each night to get some quality rest. No achy back or “waking up on the wrong side” - it is pure delight! I had no idea sheets play such an important role, but I also noticed a major difference when my Percale sheets were used. I got the Infinity pillow and now I know what it’s like sleeping on a cloud each night, no matter what angle I look at it. Thank you, Team Molecule!

So glad we decided on the molecule mattress. Had it for a little over a week now and have slept great!! My husband is a back sleeper and has had no back soreness. I’m a side sleeper and have not had any hip or shoulder soreness. The mattress doesn’t sleep hot like a lot of memory foams do and the sheets are also cool.

I'll start by telling you about my last mattress. I'm not trying to slander their company but honestly I need to warn people. It's named after a friendly ghost. Well a family member recommended that company to me, as they had one of the first 100 mattresses produced by them and love it even to this day, which is now years later. I'm not sure if something changed over the years or I purchased the wrong model, but the bed was absolutely horrible. I woke up in pain every single day and that has never once happened to me before. I was completely shocked, and less than two months later I requested a refund. The return process was pretty brutal, a little bit shady, but I stayed on top of them and eventually two and a half weeks later the recycling company came and I got a refund. Molecule was next on my list of companies to try. I refused to buy one without first speaking to a representative on the phone, and after a few emails, someone called me and answered all my questions. So I was confident I was dealing with a legitimate company. I purchased a Molecule 1, the comforter, the all season pillow, and bed came with sateen sheets. As soon as I put the bed on the frame and touched it, I knew it was going to be at least a big improvement. And that was confirmed when I laid down on that first night. After two months of sleeping on my previous friendly ghost mattress, which I would compare to sleeping on a pile of rocks, I was in heaven. Well it's been a few weeks now, and I still look forward to getting into bed every night, and I wake up feeling great. It hasn't cured my insomnia, but then the most comfortable bed on earth wouldn't be able to cure that. Let's keep our expectations grounded in reality. The comforter and sheets are great as well. The only thing I didn't like was the all season pillow. Go for the memory foam model or the essential. The bottom line is, if you're a bigger person, looking for a quality bed that's very comfortable, I am confident to recommend the molecule to you.
