Abstract (en)

[origin: EP0502223A1] The invention achieves this object by a two-part upholstered body (mattress 1) consisting of a soft elastic foam material whose parts (2 and 3) have a different compression hardness. The mutually facing surfaces have a sinusoidal profile (4) whose frequency (f) and amplitude (a) are variable. As a result, hard and soft zones can be formed in a targeted manner. <IMAGE>
