School skid-base chair on a square tube, sizes 4-6

School skid-base chair on a square tube, sizes 4-6 is a student chair for junior and middle grades. The skid-base design rests on the floor with continuous runners instead of separate legs: this improves stability, spreads the load evenly and leaves no point marks on the flooring. The square-tube frame adds rigidity and a clean look.

The overlay seat and backrest are made of bent-glued plywood 8.5–9.5 mm thick and finished with a clear water-based lacquer; corners are rounded, and the seat depth is adjustable. The steel frame is welded from square tubes 25×25×1.2 and 20×20×1.2 mm with a powder coating. Height is set with screws through frame holes at 380 mm (size 4), 430 mm (size 5) and 460 mm (size 6). Special caps on the runners prevent floor damage.

The model suits classroom fit-outs.

How many frame colors are available? Four RAL shades: yellow, lime, grey and graphite, allowing a single color scheme across a classroom or school.
