It's indeed a full-size firm mattress set for a great price delivered on-time and undamaged. No bells, no whistles, just a mattress for a lot less than what I saw at the local mattress store. It needs a frame. Only time will tell if it holds up. It's firm for sure, but that's what I wanted (an expensive pillow-top was causing back pain). Been sleeping on it for a month with no problems.
