It is Great, I love it because it’s comfortable I have not woke up with a backache since I started sleeping on this the other bed that I had I could fill the spring sticking in me and it made my back hurt. This bed is awesome. I would recommend it to anyone I also love that it has the two drawers at the bottom for storage. I can put whatever I want in there whether it be blankets or I can put like a little board down there and put like my crochet stuff down There and I like the headboard that it’s got those spaces where I can put my phone my iPad it’s got the charging station where I can hook up my chargers for my phone and stuff right there at the head where I don’t have to go getting up and go hunting for something to charge. It’s right there. I also love the side pockets on it because you can put your remotes in there and all you have to do is just re-right there and get it. You ain’t gotta get up and walk over to a table or something to pick up a remote. I have degenerative spine disease also a cancer patient I stay in a lot of pain a lot of times and this helps a lot whenever I’m feeling bad all I have to do is just go lay in my comfy bed and just relax and I start feeling 100% better.

Extremely comfortable bed. Well made and easy to set up. I let it fill out for 48 hours. A great buy. Highly recommend.

This mattress is in our spare room. We have been told that it’s comfortable and stays cool over night, no heat trapping. It came in box and was easy to set up.

Il this is an extra bed I bought for guests. I had my daughter already sleeping in it and she said it was so comfortable. I did not sleep on it, but I did lay on it and it felt great.

Very comfortable bed! Arrived in great condition and easy to set up. It began to plump up immediately but did take a full 24 hours to fully reach its size. It's just the right mix of soft and firm. I gave it to my older son for his birthday and the mattress rests on a metal frame without issue. He absolutely loves it over his old traditional spring mattress.

Way more firm than soft. Was looking for a plush mattress and after reading reviews I thought this would be what I was looking for but I'm hoping within time it'll soften up. My main issue is the sides fold In and I'm honestly missing almost 5 inches in width because of it which makes my full more of a twin. I've slept on worse but was expecting better

Reviewed in the United States on August 7, 2025 by Beautiful belly ring! But within 24 hours it fell out but likely I was able to find both pieces. After putting it back in I noticed where you screw the ball in is stripped. I tightened it and 2 days later the rings gone.
