Memory foam also comes in a variety of densities. Density ratings refer to how long it take sometime to sink into the design as well as how much weight is required to make an imprint. Something like a two pound won't take very long at all to do the imprinting. A higher number like a three or more (they go up to about five) will mean that it takes longer to make an imprint in the foam. They provide a much firmer feeling to the memory foam and they are popular with people who like that firmer quality to their bed.
According to The International Sleep Products Association, 10.8 years is the average life of a mattress and box spring. There are 312 million people in the U.S. today. Together, these numbers mean that around 48 million mattresses and/or box springs are sent to landfills every year. These estimates do not include units from hotels or dormitories, which are replaced more frequently.
Innerspring mattresses, which account for 90 percent of the 21 million beds sold last year in the United States, are pretty much all made the same way: Steel coils are surrounded by padding, and the whole mattress is wrapped in upholstery. The innerspring coil unit is the base of your mattress. It allows for even distribution of your body mass while you are lying down. The innerspring, often called the coil, is helixical in structure and as such should hold its strength and shape for many years. The coils are what offer support to your body where you need it most.
