I love it. Good comfort right out of the box. I resurrected an old bed that my father had used for my upcoming surgery.The bed worked well, but the mattress was not so good. I bought this and love it. I may just keep using the mattress after I recover.

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.

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.

For the cost, the comfort is far better than I had anticipated. As for not feeling other movement on the bed, I felt my wife bouncing her foot for over an hour. Her habit, I got no rest for that period. Y wife and I slept better than we have in a long time. Thank you

I can honestly say this mattress has made a huge difference in how I sleep. It’s the perfect mix of soft and supportive — comfortable enough to sink into, but firm enough to keep my back from hurting in the morning. It expanded quickly right out of the box and had no strong smell, which I appreciated. I’ve noticed I don’t toss and turn as much anymore, and I wake up feeling actually rested. The quality feels amazing for the price, and it looks like it’ll hold up for a long time. If you’re looking for a mattress that feels luxurious without spending a fortune, this one’s worth it!

This mattress has been great. Both my husband and I have back problems, and I have hip issues and neither of us have had any issues when getting up in the morning. We aren't sore, I don't toss and turn because of hurting hips, and we haven't had to take ibuprofen immediately when getting out of bed because of back pain, and it is comfortable enough for a full night. It isn't too soft so you sink in and can't get out of a hole, but also not too firm that your body can't get comfortable. We also have not had any issues with over heating. Highly recommend this mattress.

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.

I was skeptical ordering a mattress online as I’m sure a lot of people are. I didn’t go with the cheapest but also not the most expensive. I had never had a gel foam mattress before but this really exceeded my expectations. I don’t wake up with back pain anymore. I’m 130 pounds and I don’t sink into it too much. My dogs seem to enjoy it too. I have only slept on it for about a week so time will tell if I still love it years from now.
