ABSTRACT:
The frame of an elastic arcuate cushion according to the present invention consists of four frame plates molded integrally, and shaped to conform with the arcuate human body. The frame is provided with a plurality of longitudinal or transverse guide holes for threads that support large numbers of closely spaced beads in the space circumscribed by the frame. The thread-supported beads provide a cushion that has a full elasticity and an elevational shaping and curvature conforming to the arcuate human body, such that the user can feel comfortable when he sits and leans on the cushion.
