Bought for University student, adult weight, loves

Bought for my 19 year old university student when she came home for the summer, took the 24-48 hours to get to size and had to massage or move around the fabric on one corner that needed to expand some more. But she loves the mattress, great price for what it is.

Verified Purchase

First I would like to thank all the reviewers who recommended this product. We read your reviews carefully and decided to buy. Upon opening, it expanded well and noticed it took a good twenty four hours to completely expand. The mattress pad on top is very comfortable and and you cannot find a better mattress for the quality and price. It's awesome!

Zero motion transfer! Love the mattress

Awesome mattress, easy to move to second floor where a normal king size wouldn't fit!
