Once I unpacked this mattress, I was concerned that it wasn't going to be thick enough.  However, as an average & tall male, it's perfectly comfortable for me.  I will be using this as a daily sleeper for 5-6 months while I am traveling.  I am not sure this would suit heavier set people, but for the average person, it's comfortable, portable and convertible into a makeshift couch.  Highly recommend.
