The mattress is great. The material outside of the mattress feels kind of a mix between plastic and rubber (it's probably a better material but the feel is like that). Without sheets it does not fit well into the pottery barn cribs -- it gets stuck due to the material but once u put the sheet it slides perfectly and fits perfectly. I don't know how comfortable it is but I feel confident that I bought the best available for my baby and that it will last many years.
