Review: 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.
Review: 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
*by J***A on January 7, 2026*

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.
