Pillow-top mattress toppers Pillow top mattress toppers are filled with natural fibers such as cotton or down, or synthetic options such as microfiber. The filling is usually segmented into pockets which help it to stay in place. This is similar to quilts, though mattress toppers are usually or thicker. Most hotel beds use this type of topper, which gives them their plush feel. Eggshell mattress toppers claim to extend the life of an older bed.
Memory-foam mattress toppers Visco-elastic foam toppers are made from visco-elastic polyurethane, also known as "memory foam", a type of material that exhibits both viscous and elastic characteristics when undergoing deformation.
Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied. The foam used in the construction of
memory foam toppers reacts to both pressure and temperature. This, combined with its greater density, are properties that give them their characteristic "weightlessness" sensation. Memory foam mattress toppers are touted to optimize support and promote proper spinal alignment during sleep. and feels springy as well as responsive. There are 2 main methods of manufacturing latex:
Dunlop Latex Dunlop latex is heavier on one side than the other due to sedimentation during the foaming process. As such, it is primarily used for support layers of a bed.
Tatalay Latex Tataly Latex is flash frozen, which results in a lighter, fluffier foam. It lacks support and is used primarily as a comfort layer.
Others An electric mattress pad is made of heavy fabric with heating filaments woven into it. In the UK and Commonwealth countries this is called an "
electric blanket". ==See also==
