How Long Does It Take The Tempurpedic Mattress To Expand?

Generally, a memory foam mattress, like Tempurpedic, takes 24 to 48 hours to fully expand, but you can sleep on it right away. During the first day or two you may notice it “fills out” as it fully expands back to its optimal shape.

In addition, you may find that the comfort and support improve as the mattress fully recovers to its full size.
