We bought two of these Twin XL mattresses and put them on a split king adjustable base (also purchased at Sam's Club). We could not be happier! The mattresses are 12 inches thick. Very nice quality and comfy as can be! They work perfectly on the adjustable bases and are very comfy! The cooling top layer is no joke... It's actually cool to the touch. Overall, we love our new bed setup!! For the price, I don't think we could have found anything better! I recommend Molecule to anyone wanting comfort on a budget!! Friends who have laid on our bed assume we spent thousands of dollars. I highly recommend this mattress, especially on the adjustable base!!

I bought this king size mattress last fall 2022, but my new bedroom addition wasn't ready to move into until March of this year. I've been sleeping on it for 3 months, at first it seemed ok an firm, now I sink into it and the middle seems mushy. My back now hurts and I wake up stiff and aching. I've had to move into my old bedroom and sleep on my much firmer old queen bed. Now I have to look for and purchase a new higher quality king size mattress.

I've slept 4 nights on my new molecule arctic lux 12” king size bed and after 5 hours on it, a level 6 pain on my upper back, forces me out of bed. I'm a back and side sleeper, 180 lbs athletic man and I've never experienced this before on any bed. I will be returning it. Such a hassle to return a big mattress.

1. DO NOT HESITATE TO BUY THIS MATTRESS!! The cooling feature is next level!! You dont sink into this bed it cradles you. It so very comfortable! Don't listen to those bad reviews. Dont cheat yourself, treat yourself. Its like a spa and it relieves everything that pains you. I love this Molecule bed

Comfy but firm.

Who knew an inexpensive mattress could help you fall asleep faster? I feel like this bed is conducive to sleep. As it ‘molds' itself to the shape of your body you can feel yourself relax in its comfort. It took a few nights to get used to this new bed, but it has been a great replacement for our old bed. We ordered the king size. Movement of one of us doesn't disturb the sleep of the other. If you are in search of a new bed, This Molecule bed is worth a try. We've had it for a month.

I get super uncomfortably hot and always have the fan on but yesterday I tested the bed without turning on the fan and OH MY GOSH it's wonderful!!!! I was super comfortable throughout the night and slept so good. I also have back issues. I've had my fair share of testing out memory foam beds. Some are super firm and some are SUPE soft but this one is PERFECT for me because I have a lot of back issues and I can't sleep on anything too soft or too firm. I love it and look forward to purchasing more for my guest room for the house!!!

After much review, I decided to go on a whim with this purchase. I sleep very warm, often sweat. This bed had not only had great support but kept me cool throughout the night. My husband is also picky and he was very happy with the product, as we never purchased a mattress online. The price point was great and the mattress quality excellent. We have been loyal to sterns and foster throughout the years, but I still sleep hot. This was a complete new experience.

Great comfortable bed highly recommended had it a week and a half and sleep through the night

This is very comfortable and supportive mattress. Best mattress I have owned.
