Anti-decubitus underlayer mattress for bed has casing divided by undulating lines into cells filled with spherical infill

摘要

The anti-decubitus underlayer mattress (10) has sections (12) with multiple axes (13) defining connected points of upper and lower shells The shells form cavities to receive an infill which forms the shape of the underlayer. The dividing lines (11) extending along the axes form undulating division lines. The division lines are arranged at equispaced intervals along the mattress. The infill can be formed of spherical granules.
