I can't remember the model, but my mattress is a combo of innerspring, with both latex and gel foam. I love it. I slept for a few months on an expensive memory foam mattress, and my back hurt constantly. This bed sleeps like a dream. The only complaint is that is does sleep a bit hot, which is not good in the summer, but is great in the winter. I think that is just a typical feature of foam mattresses, though.
