Great for stomach sleeping b/c it is firm. Sides are soft, so I don't sit on it to put on shoes. I wake up hot, but I expected this, I spent $2500 for a very similar matress at Matress Firm. I would recommend this one. We call the expensive one the fajita matress b/c it folds around us & I definitely can't sleep on my stomach with the more expensive one, it's too soft. This is the best matress I've had in a decade.
