I do not like this mattress at all,im starting to wonder if they sent me the wrong one!!!! Its not firm at all its like a marshmellow and the cool doesnt happen.i have woke up with a headache every morning.i would return it but i dont know how to get it back in the box!!!!

I've had my eye on a molecule bed for awhile and I'm so happy sams carries it now at such an affordable price! Shipping was super quick! Great quality mattress and it only took a couple minutes to expand. My husband has back problems and we are both hot sleepers so this bed is perfect for us. It is very comfortable and at the same time, provides great support for his back. Would highly recommend this bed!

This is the first mattress I've ever bought in my adult life (I'm only 28), and oh my god it's amazing! I have autoimmune chronic health issues that make me sleep extremely hot at night, and I've not yet woken up in the middle of the night sweating to death. It's also VERY comfortable. You sink in a little, but not enough to get stuck in like some memory foam mattresses. Because I have health issues that cause chronic pain, with my last mattress, I would wake up hurting quite frequently, but so far I haven't woken up hurting. If you're thinking of buying this mattress, but are on the fence, just do it! You won't regret it.

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!

I've had the mattress for 60 days. It has never fully plumped up to the 12 inches that Was expected. Not to mention for a memory foam mattress this is harder then a spring coil mattress. I enjoyed the cooling effect for the first five minutes but it's still very heated

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!!

Comfy but firm.

A GREAT MATTRESS !!! Bed sheets Do Not SLIDE OFF! Very easy to set up, Zero Small and I can sniff out a mouse fart! Not too firm nor too soft , I would definitely rate it a Medium To Firm in feel. The greatest value I've seen in a mattress this year. Five Stars , BUY ONE AND REST!!

Rolled out, No offensive smell. Gave it a day to fully expand, it was probably ready after 5hrs. Comfortable, I sleep face down or on Side, no problem. It is moderately Firm. Feels clean with the antimicrobials. I used to wake up every two hours, now I practically sleep the full night.
