I wanted a firm mattress and the mattress was firm when delivered. But after sleeping on it for a few weeks, it softened up and feels like a medium-soft mattress now, nowhere near firm. However it offers a good solid night sleep. It's not easy to move around since it's a foam mattress. Beware when sitting on the side with your legs hanging down to the floor, these mattresses have no support at all on the sides. That's why I give it a so..so rating. There are better firm mattresses out there.
