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

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!!

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 I ordered the queen size thinking I wanted to downsize, but it felt too small. It was also extremely firm and I like a firm mattress. That mattress was not the same as the king I ended up getting. This one has a little more give. I was happy with this one for the first month and now a couple months in, I'm noticing sag in the middle. Not happy as I'm a 140 lb female who sleeps alone and not even in the middle. I alternate sides. Poor quality. I will see if I can return for something else.

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 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!!!

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 bought this a couple weeks ago and it has lived up to its description! It's so comfortable but still firm enough to support my back. As someone with a back injury I'm particularly happy with this feature! It also looks and feels cleaner than any mattress I've had before as well. For the quality it has the price is really good and I would definitely recommend this to anyone looking for a new mattress. Unpacking the mattress was also easily done alone.

First, I love the coolness of this mattress, I'll miss that. Second, once I got used to a new mattress and how great it felt in the beginning I soon noticed how it feels really hard once you settle in to the top layers. Now it feels even harder than my old mattress. It's going back, sadly, because the price didn't hurt my pocketbook.

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.
