Cushion

Abstract

This article is a cushion that supports the user's sitting. The circular hole part shown in the center of the plan view and the bottom view stabilizes the user's buttocks and straightens the pelvis, thereby maintaining a stable sitting posture. Also, starting from the circular hole part, as shown in the plan view and the rear view, the central part at the rear of the cushion is bifurcated and can be freely opened and closed according to the user's buttocks. The part shown by a curve at the lower part of the plan view can stably hold the user's thigh part when sitting.
