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.

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!

I'll start by telling you

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.

I would 100% recommend

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.

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!

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...!!

It’s great. It has checked

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 mattress purhcase

Honestly, the best mattress purchase I have ever made and the sale price was spot on. The mattress is a bit firm but we prefer a firmer mattress. The gel memory foam is very comfortable. I purchased these online and they were delivered in a very timely manner.

Overall great bed

Very comfortable, only wish they rolled opposite direction because center has a bit of a dip in the middle still waiting for it to come out. Would suggest using a solid frame or something if not using a box frame. Had to engineer a base due to bed frame I ordered with it had slats and not as many as needed.
