Bests & Worsts Reviews from Amazon

I got this for my 8 year old greyhound mix who's starting to wake up with what I can only assume to be painful joint stiffness in the mornings. It seemed fantastic, and it really did work...for all of 5 nights. By the sixth night, the foam in the corner (where the two side arms meet) had completely collapsed, and now provides less than a half inch of padding to the floor. While this is due to the fact that she curls up exclusively in that corner and the rest of the bed has retained its shape, I was really hoping the density would hold out longer than it did, even with constant pressure in one location.
