Was very hopeful that this topper would help my older mattress feel new. Do not purchase if that's what you are thinking. This was so thin I could lay my remote control on it and it would sink to the bottom instantly. There was zero give at all. We didn't even sleep in it but one night and removed it immediately! Not the quality I expected from the Tempurpedic name.
Great topper but I would strongly suggest have something on each corner to fit over mattress to help keep in place. Also the surface is very difficult to keep smooth, has to be worked with each morning, not fun! We ordered 2 I should have only ordered one to see how we liked it.
