A slipcover (also called loose cover) is a fitted protective cover that may be slipped off and on a piece of upholstered furniture. Slipcovers are usually made of cloth. Slipcovers slip on and off, they come fresh, and may be removed for seasonal change, cleaning, moving, or storage.
In the days before home air conditioning was available, it was common to put slipcovers on upholstered furniture in the hot months of the year to protect the upholstery fabric from sweat.
In recent years, there has been a renewed interest in custom slipcovering driven by the interior design industry and the popularity of the very casual shabby chic design style.
