Abstract
This product is a portable seating device used to support the buttocks when sitting upright. The left and right side panels are curved inward to prevent the insides of the user's feet from coming into contact with them, preventing pressure on the feet when sitting upright and increasing comfort. When in use, the seat provides broad support for the buttocks, while the left and right side panels assist in proper foot positioning, allowing for a natural sitting upright position. In particular, the curved shape prevents interference between the feet and the side panels, reducing strain on the feet even when used for long periods of time. When storing, the left and right side panels can be folded under the seat.
