School Chair T-shaped on Flat-Oval Tube with Seat Depth Adjustment, HPL

The T-shaped school chair on a flat-oval tube with HPL coating is a student chair for middle and senior grades, sized for size groups No.4–7. Its main distinctions are the wear-resistant HPL coating of the seat and backrest and a tool-free internal height mechanism that automatically locks the height at the required size group without screws or keys.

The frame is welded from flat-oval tubes 50×30, 38×20 and 30×15 mm with a powder coating. The seat and backrest are made of bent-glued plywood 8.5–9.5 mm and covered with HPL plastic 0.4–0.5 mm thick, resistant to abrasion, moisture and disinfection; the corners are rounded. Height is set by the tool-free internal mechanism with automatic locking at 380 mm (No.4, optional), 430 mm (No.5), 460 mm (No.6) and 510 mm (No.7); additional plastic clamps hold the position. The seat depth is adjustable, and plastic tips on the tube ends protect the floor.

The model suits classroom fit-outs.

HPL is a dense plastic 0.4–0.5 mm resistant to abrasion, scratches, moisture and frequent disinfection.

How does the tool-free height adjustment work? The internal mechanism automatically locks the chair at the intended size group — height is changed without screws or keys, and clamps hold the position further.

Can chairs be ordered in several HPL colours? Yes, beech, milk oak, grey and pearl artisan beech are available, so you can keep a single scheme or assign colours per room.
