Mutipurpose cushion system

Abstract

A multipurpose cushion system that meets multiple needs by providing at least two distinct cushion designs: a convex shaped cushion that acts as a closed seat type cushion and a concave cushion designed as a hippocrepiform-shaped neck cushion. The convex outer cushion casing has a circular or regular polygonal shape that includes a flat front face and a flat back face and a side wall extending between a perimeter edge of the flat front face and a perimeter edge of the flat back face, the outer cushion has a closeable opening removed from both the perimeter edge of the flat front face and the perimeter edge of the flat back face. The two cushions are nested to provide a synergistic effect in which the concave cushion acts as fill for a closed convex seat type cushion and the outer convex cushion casing acts as a cover for a concave (hippocrepiform shaped) neck cushion. The hippocrepiform neck cushion shape and dimensions facilitate function as cushion for a seat cushion while also optimizing neck support.
