## Customer Reviews

### ⭐⭐⭐⭐⭐ Sleep great so far
*by E***. on May 11, 2025*

This mattress is comfortable for me, as I am 220 pounds and 6 feet tall. Previously, I had a Sealy foam mattress that was 5 1/2 years old. I bought a new Sealy because I was moving, and it was a pain to transport.Although this mattress is described as plush, I wouldn't classify it as plush; it's more of a 6.5 out of 10. Plush doesn't exist in any 3 out of 10 scale nor in any 10 out of 10 scale for firm; a 9 out of 10 is considered extra firm.Although if you were to push your fist into the mattress, it would feel plush, I considered this mattress medium, not medium soft. The foam pushes the body up, making it great for side sleepers. If you have never tried a foam mattress, you cannot compare it to the old metal springs; I'd recommend foam any day! Just not the cheap foam mattresses.

### ⭐⭐⭐⭐⭐ Great for a guest bedroom
*by A***R on May 17, 2025*

Bought this for my 22 year daughter’s bedroom. It is very comfortable to lay on, she loves it!

### ⭐⭐⭐⭐⭐ Amazing mattress
*by T***F on May 11, 2025*

One of the best mattresses I've owned. I had this in a queen previously and the king is no different. Right amount of support without being too soft.
