The Tempurpedic range of beds and mattresses are certainly one of the most popular mattresses to buy, and most beneficial to sleep on. However, in order to experience these benefits you might feel that your Tempurpedic bed needs breaking in.
It usually takes a few weeks for some mattresses to break in. When you first sleep on a Tempurpedic mattress you might be surprised by how firm it is. These mattresses do have comfort layers that make the initial feel soft, but a 5-6" bottom layer which is a firm foam.
Even after a breaking in period, Tempurpedic mattresses still retain a pretty firm feel, although some models like the Deluxebed and CelebrityBed do have a softer feel than other models.
