1.  My queen size sheets wont fit it, and they are deep pocket sheets. It's a very large mattress.  In my opinion it should be cut down 1" on all sides and then it would work with queen sheets.  2)  It won't bend with the adjustable bed, but just slides up over it, apparently it's too thick to bend as it should.  Other than that, it's fine.  Firmer than I like, but that's my fault, I got the firm.
