A stool designed for piano playing, with a focus on smoothness in its design. The outward chamfer of the four legs and the diagonal braces beneath the seat forms a beautiful structural. The seat is topped with a canvas cushion, providing comfort for the piano player while seated. Underneath the seat, there are grooves that serve as handles, making it easier to maneuver. Different from typical piano stools, this stool is designed to accommodate different scenarios on each side. On one side, an additional horizontal support is added underneath, allowing people with shorter height to rest their feet comfortably when used as a regular stool. On the other side without the horizontal support, it is suitable for piano playing, allowing the feet to step on the piano pedals with ease.
