Student Chair, Cantilever Sled Base on Round Tube, HPL, No. (4)5-7

This student chair with a sled base on round tube and HPL surface is a model for middle and senior classes, adjustable for height groups No. (4)5-7. Its main structural difference is the sled (runner) base instead of four separate legs: it spreads the load evenly across the floor, does not wobble on uneven surfaces and slides smoothly without scratching the flooring. Such a chair is easy to lift onto the desk during classroom cleaning.

The seat and backrest are made of bent-laminated plywood (8.5-9.5 mm) faced with 0.4-0.5 mm HPL plastic — a surface resistant to moisture, abrasion and disinfection that is easy to clean. The corners are rounded and the seat depth is adjustable. The metal frame is welded from round tubes 32 and 25 mm in diameter and a flat-oval tube 30x15 mm with powder coating. Height is set with screws through the frame holes to three positions by the child's height. Plastic end caps on the runners protect the floor.

Why is a sled base better than four legs? The runners rest on the floor along their full length, so the chair does not wobble on uneven surfaces, slides quietly and does not scratch the flooring — reducing floor wear in the classroom.

Why HPL in school? HPL plastic resists moisture, scratches and disinfectants, wipes clean and keeps its look for years.
