Aired up fast, no bad smell, very comfortable overall. It's been several months now since I received the item, and I am pleased with the quality, although if you're on the heavier side (+250 lbs) , I'd recommend monthly or bi-monthly rotating of the mattress, particularly if you don't sleep in the middle of it (couples, mostly), as memory foam does compress over time. A more expensive one probably wouldn't need it as often, but rotating it every other month has kept it nice and flat for my partner and I (combined weight 500 lbs ish), and at the price point it was pretty damn good (I believe I paid around $300-350 at the time of purchase but it was black Friday week so there was a good discount). If you're lighter than us, you'll definitely like it, assuming the firmness agrees with you. My partner (the heavier of us) finds it slightly too soft, but still relatively supportive, and adding a memory foam triangle thing across the headboard under the pillows (intended to fill the headboard gap) has helped *substantially*. I find it very comfortable.

This has been my first time buying a new mattress. And my first time buying a foam one. It's a 300 lb man I have to say this is a wonderful bed. I have slept great on it since I got it, I did give it the entire full 3 days that they recommend without sitting or touching it to let it expand fully, I don't know how much that plays into my experience but I recommend following the actual instructions. I know that's generally not convenient, but do it anyway. I could not be happier with this thing. Even if it only lasted 5 years, which most beds are rated for seven, it would be worth it to get another. It's just great.

This mattress is remarkable! Has quick set up time, medium firmness I immediately felt a burst of comfort as soon as I laid down! I’ll definitely choose this bed again and never less to mention that it doesn’t have a weird smell, this bed is definitely one of the best.

Comfy mattress. I wish it was a little firmer. I bought the 14” thick and if I could I’d buy the 12”. The thicker mattress hides too much of the headboard. I’m happy with my purchase.

I bought a full and a twin for my daughter’s bunk bed. It does squish down when grown ups sit on it but pops back up. It’s good firmness for a child or toddler - she’s just now 3 years old and has been using the mattress for 4+ months. She sleeps great. She has a condition that flares up with inflammation in her hip or knee with viral illnesses so I was really wanting something firm for her little body and good quality. I can also fairly easily change the sheets because it’s not so heavy that I can’t maneuver the fitted sheet or back side or pull it up and out when I need to.

I did not expect the quality and comfort this product offers. Everyone who uses the bed can't believe the quality for the purchase price. It sleeps great and I was able to set it up by myself.

We ended up getting this mattress because the previous one that we had was on a recall list so we had to get a refund for it. We then gave this mattress a try since it had "good rating" and a decent price. 2 day after fully letting the mattress break in. We woke up feeling like we slept good but man we started feeling hip and back pain afterwards. Figured it was still taking shape we gave it a few more week. But got worse. The mattress is too firm, which my wife liked since you can't feel your partner move while sleeping. But not worth having pain. Material felt good and like the idea of the top being able to be removed for washed but not worth it.
