Amazing mattress! Take my word that this mattress is the perfect amount of plush and firmness I love this mattress! Super easy to set up and it instantly got to size. 10/10!

    • I use it with an adjustable bed frame
Style: 10" Size: Full
So comfortable and glad I already had this bed as I injured my back and helps waking up without being stiff. Also I use my bed with an adjustable bed frame the best.

    • Very nice. Plush is better than medium.
Style: 12" Size: Twin XL
I was having restless sleep and suspected my mattress was at fault, I tried out a family member's mattress and felt completely comfortable on it, so that was the proof. That mattress (purchased in 2020) was identical to this one except for being categorized as medium instead of plush. Same 12" height, same Sealy brand, same bed-in-a-box foam construction. What I didn't like about the medium mattress was my calves felt like they were "riding on top" of the mattress, which caused my feet to turn out uncomfortably. I thought if I had to sleep on that, I'd need to put a folded blanket under my lower legs to get the right feel. I just unpacked this new plush mattress today, and in the first moments of laying on it I can feel the difference under my calves, it's just right. The difference between medium and plush is not dramatic, but it is noticeable. Don't be afraid that a plush will feel like a hammock; this has ideal support. It's been my experience that all-foam bed-in-a-box mattresses tend to feel firmer than advertised, keep that in mind when shopping. I was thrilled to find this "plush" one at such an affordable price. ... show more

Style: 14" Size: Queen
Been sleeping on it for over a year now and its still going strong. Extremely perfect not to hard not to soft forms well to the body. I have hip dysplasia and degenerative disks and if I try to sleep on anything else I cant walk right the next day.

    • Great ultra plush bed!
Style: 12" Size: Queen
I was extremely nervous to buy a mattress online without testing it out in person. I got the ultra plush bed. As soon as I opened it up, I laid down on it, and I know that you need to wait about 48 hours for it to fully inflate, but let me tell you I immediately took a nap on that bed. I have never been more comfortable. It's crazy because while laying in bed I can feel my spine being straight. Even though I'm lying on my side, I've never slept in a bed like that. It is very plush but not to the point where as soon as you sit down you sink and you can't get back up. You do sink a little bit, but it complements your body curves. It's been a really long time since I've been able to sleep this well. Update: I loved this mattress at first but the spring and summer time have been terrible. I literally wake up in a pool of my sweat everyday. I am never hot , and this bed makes sleeping terrible if it's warm out. I even bought multiple mattresses toppers that are cooling and they don't even do anything to help. ... show more

    • Comfortable but not necessarily cooling.
Style: 14" Size: King
Comfortable mattress but still not a "cooling mattress" as advertised. This mattress sleeps on the warm side. It will be okay for winter nights when it cools off.
