cushion

Abstract

This product is a cushion that the user places on a chair to sit on. As shown in the plan view, perspective view, etc., the cushion has a hole in the center, and the portion behind the hole is bifurcated, allowing it to be freely opened and closed to fit the user's ischial bones. This is designed to prevent the cushion from directly contacting the ischial bones when the user is seated by creating a cavity between the hole and the bifurcated portion behind the hole. Additionally, the portion shown in the center of the front view is raised in a mountain shape, with both outer portions gently sloping from the outside to the inside. When the user sits, the shape of the front of the seat holds the user's thighs and supports the ischial bones, stabilizing the sitting posture.
