|Mattress Protector (a non-padded mattress covers)
||Non-padded mattress covers (sometimes called encasements) are designed to help protect a mattress from exposure to things that might damage it-like water, dust and dust mites, mold, pet dander, and other allergens. Non-padded mattress covers can be made of cotton, vinyl or super-tightly woven polyester fabric, and they usually zip up to totally surround the mattress. (You can get these encasements for box springs, too.)
|Fitted Mattress Pads
||A fitted mattress pad works like a fitted sheet-a ring of elastic around its bottom edge helps secure it to the bed. Unlike a sheet, however, a fitted mattress pad is quilted on top to provide a comfortable sleeping surface-and to circulate air to help sleepers' body temperatures stay more even during the night. Fitted mattress pads are a good match for most standard-size mattresses.
|Guaranteed-to-Fit Mattress Pads
||Because it has a quilted top, a guaranteed-to-fit mattress pad helps make a bed feel more comfortable. It also offers better temperature regulation. The side panels of a guaranteed-to-fit mattress pad are made with an elasticized fabric that helps it attach securely to deeper mattresses, usually up to depth of 24". (These mattress pads are sometimes referred to as Tailor Fit or Expand-a-Grip.)
|Visco Elastic Mattress Toppers
||These mattress toppers, sometimes called memory foam, are designed to provide additional support to sleepers. They conform to the body because they're made with a temperature-sensitive material that contracts more where the body is warmer, but stays firmer where the body is cooler. Another benefit? These mattress toppers can also dampen motion when a sleeper moves. Visco elastic mattress pads are placed on the bed underneath the fitted sheet.
|Fiberbeds and Featherbeds
||These mattress toppers are essentially mattress-sized pillows designed to create a more comfortable sleeping surface. Fiberbeds and featherbeds cradle body areas that don't come into contact with the mattress. These stuffed pads are made with natural materials like down and cotton or with man-made materials, and can be placed underneath or on top of a fitted sheet.
|Convoluted Mattress Pads
||Also referred to as egg crates, these dimpled foam pads are designed to improve body weight distribution. They add support, help reduce tossing and turning, and add a layer of cushioning to the bed.
|Heated Mattress Pads
||These mattress pads are electric and come with warming controls. Some come with dual controls that let you have different warmth settings for each side of the bed.
