How Quickly Does A Swedish Tempur-Pedic Mattress Sag?
Over years of use, any visco foam mattress, be it Tempurpedic or other, no longer regains its exact, original shape. A sag in the center of the bed becomes a permanent feature. The question is, does this happen in a few years or will you enjoy 10 plus years of sleep before you are forced to buy a new bed or mattress? I may not fully understand the physical process in the Temper foam but this much I know. Larger cells crumble quicker over time because they suffer more strain than smaller cells. With more air than substance, wear in low density viscoelastic foam may become visible in as early as 3 years. But there is another thing worth considering. Even when part of the cell structure in high density memory foam crumbles, there are many more billions of cells left underneath to continue providing support for a long period of time. In the low density stuff, however, there are fewer cells. When the cells at the top of the Temper-Pedic Swedish mattress crumble, there are not as many cells
