Comfort +++
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!

A no frills mattress that we like very much (we want no frills)
I have enjoyed this bed VERY much, and the wife and baby likes it also. No frills, just a comfortable bed, the way we like it. I like this sealy dreamlife 8" better than a queen nova foam thicker mattress we have purchased from costco. Just my preference.

Very nice. Plush is better than medium.
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.

Comfortable and convenient
Purchased the full-size mattress which was delivered conveniently to my doorstep. Box was a little heavy and bulky, but I carefully carried up a flight of stairs on my own. Right size to maneuver. Unpacking was easy. Pulled out of the box, laid on bed frame. Very nicely packed. Removed the plastic wrap. Mattress would not get wet even if box got wet. There was no noticeable smell and it “inflated” in a few minutes, however I waited a couple days before installing bedding. I like firm mattresses, but experienced the medium firm purchase was very comfortable.

Good for side sleepers
It’s decent for the price but not the best for back support. It’s comfortable tho and works well for being a side sleeper . Purchased for our guest room so don’t have to sleep full time in it .

Great night sleep!
Bought these for my daughter’s bunk beds and they are super comfortable. Might upgrade my king bed with one soon!

Great ultra plush bed!
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.

Not great for the money
Want to give this 1 star only because I ordered a 14” mattress. I let it expand for 72 hours and a month later it’s still only 12”. Disappointing. As for comfort, it’s not too soft and not too firm. I wanted as plush as possible. This is soft but you do not sink in at all, but yet it’s not firm either. So I like the comfort of it on my shoulder. It does sleep very hot unfortunately
