I have needed this for so long that my back was screaming... JUST DO IT! There are so many choices when it comes to mattresses today that I was a bit overwhelmed when trying to decide on which one would be best suited for my body style and the amount of time that I am pretty much bedridden. My two little dogos sleep with me too. From their behavior... they seem to be as pleased with this purchase as I am... so far. I'm hoping that it will hold up for a good period of time and provide me... my back... and my furbabies the same comfort that it does right now.
