Abstract (en)

[origin: EP0870449A2] Bed mattress, of the type consisting essentially of a stratified expanded-foam panel formed by the arrangement, on top of one another, of at least three layers with different load-bearing and/or air-permeability characteristics. The main layer, which is situated in the middle of the other two layers and is basically assigned the load-bearing function, has a thickness variable along the length of the mattress. Said middle load-bearing layer has high load-bearing characteristics, with small-size closed cells, and its thickness varies from a minimum of about 50 mm, in the region of the neck zone of the sleeping person, to a maximum of about 130 mm, in the region of the trunk and respectively the pelvis of the sleeping person. <IMAGE>
