Curved surfaces are created when geometric shapes are twisted and positioned in three dimensions, with the bottom turning into a shadow. In relation to one another, they can be square, round, trapezoidal, semi-circular, or connected with the surface. However, the seat is a very stable little pier. The side of the pier is supported by 3D bentwood, and the soft cushion inside bulges out the edge, similar to a puff, with strong actual support, which can freely change the sitting position.
