Holly:
Yes ... we rotaed the mattress and built a foam wedge so that person who gets the shaved off edge of the mattress can keep their leg on the bed at night.

we also flipped the mattress to find that there IS a wrong side. One side of the mattress has harder foam then the other ... ouch

We ordered a new mattress which actually arrived today from Camping World .... an inner spring mattress 8" thick and I HOPE THIS WORKS !!!!!!!!!
My back was aggrivated by the mattress and then I ended up pulling all the muscles in my lower back OUCH

but we are going down in the garage tonight and sleeping in the PC on the new mattress to see if this will solve the problem.
Good Luck
