Cushion

Abstract

This article is a cushion for sciatica care. In the plan view, the part shown at the middle position between the left and right has a structure with holes in an arch shape. As shown in the right side view and the left side view, it has a shape with a downward slope from the front to the rear of the cushion. When the user sits, the inclined part towards the rear prevents forward slippage, the arch-shaped hole part alleviates the contact with the user's sciatic part, and stabilizes the sitting posture.
