Good Couch, Bad Bed

I bought this mattress at Mattress Discounters (Name was Europa Apollo there but specs are identical). I spent about an hour in the store trying it out, rolling over from my side and back. I loved it in the store. The mattress that was delivered to my house felt significantly firmer than what I had remembered in the store. The salesman assured me that I had to "break it in" and after a few nights it would feel just like the one in the store. It has been over two weeks and I am still tossing and turning because of the pressure points on my shoulders, hips and lower back. It feels comfortable when sitting up, like it's a couch. But if I want to sleep for more than an hour I have to retreat to the futon. Unfortunately, I need a bed, not a second couch so I will most likely be eating the 15% restocking fee and $80 delivery charges plus price difference when I take advantage of the 60 day comfort guarantee. This bed is uncomfortable enough for me to justify the cost.
