A breathable knitted jacquard cover wraps the tight top to manage heat and maintain a cool-to-the-touch surface throughout the night.

My goodness. This was like sleeping on cement with a sheet over it. My back is screaming after 2 days. I’ve just returned it and ordered the bed I should’ve in the first place. There is nothing medium about this bed it is extremely FIRM and lumpy to boot.

I love this memory foam mattress! It is great quality for the price and is very comfortable. It does come in a box and dont be alarmed the first day it needs to stretch out and unharden. Overall, its great! If you do get a stain on it, it does come out which is wonderful! ) I purchased it for a queen bed and it is great!

Mattress Size:Queen,

Thickness:8"

Mattress arrived with no paperwork whatsoever. I was expecting something as far as instructions, invoice, etc Figured out that I needed to remove the plastic and allow mattress to expand, but after more than 5 days, it seems to have inflated unevenly with the corners lower than the rest of the mattress. I also ordered the Cassey platform bed in queen/full, but this mattress doesn't fit he bed. As you can see in te picture, the bottom the mattress doesn't reach the bed frame all the way around. if you stand back and look a the mattress, you can tell one side never fully inflated, thus the problem.This leave a nice 2-3 inch gab between the mattress and bed frame, which I am not happy about. Also, there is a funny odor in the mattress that hasn't thus the odor contained in the matress I assume will dissipate eventually. I suspect it's the gel or some other material common to this type of product,
