I read a lot of the reviews before ordering, and there is truth in all of them. Below are my thoughts:

Good:
-Material Quality
-arrived before expected
-very plush (was actually worried that it may be too plush, but my back feels great)
-good on my allergies

Bad:
It is definitely warm (this is my first non-spring mattress)

Ugly:
The edges, as others have described are basically non-existent. We've lost almost a quarter of the sleeping area from our previous mattress. Being anywhere near the edge means you will roll off. Thus, the queen version (which is what we have) is only a one-person mattress. My wife and I find we have to huddle in the middle of the bed, which when combined with the additional heat of this mattress, makes it an uncomfortable night.

I would not purchase this bed for my situation again.
