The mattress is great. It is firm and set up was easy. Given the way it rolled out, I was a little worried that the mattress would be too soft to sit on the edge without sinking in/sliding off, but the edge holds its shape. Nothing else to say other than we're happy with the king size.
[This review was collected as part of a promotion.] Absolutely love our new mattress from Casper, Casper Hybrid. It is like sleeping on a cloud, which I do not know how it feels unfortunately, but I think it would feel like our mattress actually.
We replaced our pillow top mattress with the hybrid Casper and could not be happier. I used to feel every movement my husband would make, and now I don't feel anything at all! Our last mattress was so expensive and after only a few months we already had a dent where my husband slept, and so far we don't have any issues like that at all. I would highly recommend this mattress to anyone!
