I would not recommend to to heavy people. The first two days we sunk in. It is a bit better, but still hard to get out of. My wife and I are in our late sixty's, and overweight (fat). Bought it because it was supposed to be firm, not so much. Once you get in it, it is great. Will never order an in the box mattress again. Will buy a new innerspring mattress, and move this to the guest room.
