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 “fill outs” as it fully expands back to its original shape.

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