        High mattress
        It is very comfortable. We like a stiff mattress. But it is a little high for me, a short person, to get into. It’s mostly for guests who are younger and taller though.

        Ultra Firm Sealy Posturepedic- Disappointed
        I wanted a very firm bed, and this is ultra firm. But it’s not the best quality. I can feel the springs pushing back up against me, and good quality mattresses don’t do that. Also, the foams used on the top, do not provide any pressure relief. There isn’t foam on top at all.  If they had included some firm foams on top, this would’ve been a much better Mattress.
I am disappointed. This isn’t a good quality mattress- Sealy Posturepedic doesn’t make the ‘top quality’ mattresses these days. 
  And if I want to exchange this, they don’t even have much of a selection at PC Richards.
