It’s firm not medium

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

DISAPPOINTED

My bed is currently on the floor because the product was not manufactured properly. There are gaps, holes half drilled or no holes drilled at all!!!!

Pure Delight!

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!

Slept on this mattress while

[This review was collected as part of a promotion.] Slept on this mattress while on vacation and liked it so much ordered one when I got home. No issues or concerns with order, shipping, or unpacking the mattress. Love the sound sleep my wife and and I are getting.

No more hip pain!

[This review was collected as part of a promotion.] We purchased this mattress after sleeping on one as a guest over the holidays. How wonderful to wake up with no hip pain, stiffness, or general body aches. Amazing! It arrived quickly and there was no offensive odor, so we were able to enjoy it the next day.

My back is KILLING me!

[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.

What a Joke

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...!!

A true game changer

I have thoroughly enjoyed my mattress since it came in the mail. There is no chance I will be returning it. As someone who prefers a firmer, more supportive mattress, this offers the perfect balance of tension and cushion. After a few days of adjustment my body has come to embrace the sleep provided by this mattress and even my dreams are more vivid. I have since purchased a pillow and look forward to bed time every night.

ABSOLUTE MUST

[This review was collected as part of a promotion.] 100% LOVE and highly recommend this mattress. My chiropractor and massage therapist both recommended it so I decided to give it a shot based on the 100 night of sleep special that was being offered. I love it!
