Abstract
A cushioning material, comprising a lower filament cushioning layer of relatively high rigidity and high perviousness to air obtained by compression molding in a stated shape three-dimensional curled short fibers of polyester filaments of a relatively large denier number thereby producing a shaped mass of filaments and applying adhesive agent to the shaped mass thereby binding the points of mutual contact of filaments therein and an upper filament cushioning layer of relatively low rigidity obtained by compression molding in a stated shape three-dimensionally curled short fibers of polyester filaments of a smaller denier number than said polyester filaments thereby producing a shaped mass of filaments and applying adhesive agent to the shaped mass thereby binding the points of mutual contact of filaments therein, with said upper layer superposed on said lower layer.
