The chair consists of an overlay seat, backrest and metal frame. The seat and backrest are made of bent-glued plywood 8-9 mm thick and covered with colorless, environmentally friendly water-based varnish. The corners of the seat and backrest have rounded radii to prevent injury. The metal frame is made of round pipes with a diameter of 25 mm and 32 mm. The backrest and seat are attached to the frame with screws and nuts. The height of the chair is adjusted using screws in the frame holes. The frame is powder-coated. Adjustment is made using a through-bolt and nut clamp with a cap nut fixed in the pipe to prevent loosening during loosening. Plastic tips are attached to the ends of the frame to prevent injury to students and damage to the floor. An internal polyurethane bushing is installed in the height adjustment points, ensuring smooth adjustment and eliminating creaking and scratches when adjusting the height. The backrests and seats are attached to the chair frame using special mushroom-shaped bolts and rounded nuts, which prevents injuries and damage to clothing. There is a hole on the bottom of the frame through which the height group markings will be visible when adjusting the height of the chair. The color marking according to the growth groups is applied in the form of a circle of about 10 mm. Also, the metal frame is laser engraved with a scale marking the growth groups.
