It's wonderful to sleep on, but mine wasn't even because it shifted and looks like a staircase at the foot of the bed. But as I said it's really comfortable

The mattress is comfortable and conforms to the body right away- there really wasn't a “breaking in” period compared to other foam mattresses. It was purchased based on the affordable price and the good reviews. Very happy with this mattress.

The mattress is comfortable enough and cooling, however, every set of sheets I have tried on the bed slip and slide around. I may need to purchase a mattress cover in the future to prevent the sliding.

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.

In the interest of Full disclosure my old memory foam before this was broken down and sunk in…. That being said here is my assessment: it feels like a cloud but doesn't sink in, it's best when sleeping on your back but decent for a side sleep too, I do still wake up with aches but that could be because I'm 40 and have health issues so use your own discretion there with that info…. The only beds I've ever slept better on were a purple premier 4 and a sealey double pillow top that we would rotate and flip every month for the 12 years we had it.

I used to sleep only on spring mattress that are firm (no pillow top). After moving to a smaller town there are no suitable mattress stores in town so I decided to give this Molecule mattress a try. I let it expand for 3-4 days before use, and the edge took 2-3 days to expand fully. Honestly first two nights I woke up with lower back soreness in the morning and was planning to return, but from the third night on I don't feel sore anymore. They say it takes sometime to break in a new mattress. By the way I chatted with Molecule customer service before buying and that person said this mattress was newer than their Molecule 2 and the build would be more like Molecule 2 than 1, in case you're wondering.

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 seen Molecule ads on my IG feed a lot - really glad Sam's starting carrying it! Couldn't believe the price - and honestly I was a bit reluctant to purchase since this model isn't sold anywhere else and I couldn't find any external reviews about it. But took the risk a few weeks ago and so far, really pleased. Highly recommend it if your'e a hot sleeper like me.

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.

First night on my new mattress and found it wonderfully supportive, didn't toss and turn as usual. While the Molecule was a bit warmer than my previous spring coil mattress, it wasn't as hot as the other memory foam ones I've tried, and wasn't uncomfortable. I unintentionally slept over nine hours, haven't done that in years, so I guess I'm going to have to bring my alarm clock out of retirement!
