T-shaped student chair with a round tube frame, size group 5–7

Backrest dimensions: 410 x 200 mm; seat dimensions: 410 x 410 mm. The seat and backrest are made of 8 mm thick bent plywood and finished with a clear water-based varnish. The corners of the seat and backrest, as well as the front edge of the seat, have rounded corners to prevent injury. The chair frame is made of round tubing with diameters of 32 x 1.2 mm, 25 x 1.2 mm, and 30 x 15 mm, finished with powder coating. The backrest and seat are attached to the frame with screws and nuts. The chair’s height is adjusted using screws through holes in the frame and legs, between which a plastic spacer sleeve is installed. Plastic caps are attached to the ends of the frame to prevent injury to students and damage to the floor. The frame features markings for height groups to assist with chair height adjustment.
