Mattress-foam material core has cuboid shape and extends over width, which is less than mattress length, where mattress length is divided into three regions

摘要

The mattress-foam material core has a cuboid shape and extends over a width, which is less than the mattress length. The mattress length is divided into three regions (A,B,C) which are designed differently in the upper side and the lower side and are provided with grooves (11,12,13,14,15,16,17,18,19). The grooves extend over the entire width of the mattress.
