Feel the memory foam. Tempur-Pedic designates its mattresses as soft, medium-soft, medium, medium-firm and firm.
Pay attention to what the material that covers the memory foam is made of. Tempur-Pedic materials include a microsuede, a silk-cashmere blend and a silk-and-bamboo blend.
Ask how much the memory foam will conform to the weight and shape of your body. Tempur-Pedic rates the "confoming" as low, medium or high.
Check to see if the Tempur-Pedic memory foam mattress comes with handles, which makes for easier installation, flipping, rotating and cleaning.
Decide on the size of mattress you want. Mattress sizes available can vary from style to style. For example, the Tempur-Pedic Advantage Bed is available in twin, twin long, double, queen, king, split king and California twin; the Tempur-Pedic Original Bed is only available in twin, twin long and double.
