When my husband saw it at the beginning he said he didn't like it. He said he could feel the box spring because this mattress is very thin. It's been a week since we started using this mattress and now he says he likes it. I guess it was his imagination that he thought he could feel the box spring since it looks so thin. This mattress is very firm and I like it. Over all I think this is a good deal for a memory foam mattress.
