Chair with a trapezoidal open space in the backrest

Chair of oak resting on four legs. The front legs are chamfered and rest on black-stained discs with convex sides. The rear legs continue into the back stiles and widen from below, then taper upwards at the middle. The backrest is composed of three panels. These are shaped such that a triangular form is created at the top and an open trapezoidal form at the bottom. The two outer panels are connected to the black-stained central panel by means of five beads on each side. The seat is upholstered with striped fabric in beige, red and purple.
