Abstract
The invention of this application relates to a cushion body, well suited for use as a seat cushion of a motor vehicle, consisting of a spring body which is deformable under a load, and is air and mositure permeable. The cushion also employs an air permeable cover material which is stretched over the cushion and is underlaid with a buffer layer which has a substantial content of cellulose fibers. The spring body consists of fibers with hydrophilic properties and a titer of 3 to 50 dtex, which fibers are combined to form a spatially oriented network, and are cemented together where they intersect.
