Like some other reviews, this mattress is not 8 inches. It is 6and a half at best. Also it is not even, one end is lower than the rest.

It is for my daughter. But she only slept on it for half a night. It is firm, at least for a kid. I tried it for a few minutes, it feels very firm. But it also feels not like memory foam. More like hard regular foam, the craft type. My other memory foam mattress all have a gel feeling. This one doesn't.
