This mattress at 11" is easier to change the sheets than other brands that are 15" and so heavy I could not lift them to change the sheets. Since getting this mattress, my shoulder pain has improved. With my old mattress I would wake up when I shifted to that shoulder, but not so with this mattress. That was my main reason was selecting the Tempur-pedic adapt medium hybrid. I don't know yet how this will be over time, but good so far. I would have preferred a firmer edge around the sides of mattress.
