Just received a California king today.. What a joke the box literally looks like the have been storing these in a hay field. Now I get to waste a hour and a half taking this joke back to Costco!! No business should have products arrive with such lack of first impressions...!!

[This review was collected as part of a promotion.] Comfortable at first but is horrible on the lower back band. My back hurts after a few hours into the night. My back has never hurt so bad. Just went to the chiropractor and was extremely out of alignment. Very disappointed in this mattress.

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!

Bought mattress for my teenage soccer player. She loves her new mattress. She says her sleeps are now cooler and the mattress is extremely comfortable eventhough it is firm. On another note, molecule customer support is superb. Had an issue with delivery of the mattress. They responded quickly and replaced with a new mattress within a week. Was very impressed. Thanks Molecule.

[This review was collected as part of a promotion.] We got this mattress for our guest bedroom after recently moving. We wanted an affordable mattress that was good quality and would hold it's shape. We have gotten compliments from both guests who have stayed in the guest room! I'd say that is a success!

It’s great. It has checked off all the boxes for us: soft yet supportive memory foam good for back and side sleepers, cool and comfortable (we also have the sheets), and great for motion transfer. This was our third online bed and it was also the most affordable. I would def initely recommend this to someone looking for a memory foam bed.

Best investment so far this year. If you want quality, then look no further. When I get home from work and instantly lay down I feel the softness of the bed. Great on your back, side sleepers, and stomach. I think I’m all 3 of them. I recommended getting their sheets too. The cool feel really makes a difference when sleeping. Best rest I’ve gotten my whole life so far.

I have nothing to complain about. With my old mattress I used to wake up throughout the night with neck and back pain. Ever since I got this mattress I’ve been sleeping through the night and haven’t noticed any pain at all. I would definitely recommend this for any stomach sleeper.

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!

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.
