Height-adjustable student chair
PP shell

The HZ-ST-620 is a height-adjustable student chair with a one-piece polypropylene shell on a powder-coated steel frame. The seat height sets through a numbered telescoping column, so one chair covers several pupil sizes and grows with the child. The contoured seat and waterfall back flex for comfort, a moulded grab-handle cutout makes the chair easy to move and hang, and a wide twin T-base with ABS end caps keeps it stable on any floor. Available across a full range of shell colours.

Stepped height adjustment

A numbered telescoping column sets the seat to the pupil's size and locks in place, so one chair covers several EN 1729 sizes and grows with the child — useful for mixed-age rooms and shared spaces.

— 02

One-piece ergonomic shell

The contoured seat and waterfall back are pressure-moulded in a single piece of polypropylene that flexes for comfort, wipes clean, and has no seams or fabric to trap spills. Ventilation detailing keeps the seat cool.

— 03

Grab handle & stable base

A moulded cutout in the back doubles as a carry handle and a hanging point for cleaning. A wide twin T-base with ABS end caps keeps the chair steady and protects finished floors.

7-stage anti-rust frame

The steel frame goes through degreasing, phosphating, electrostatic powder-coating, and high-temperature curing, holding its finish in coastal and tropical climates. 5-year structural warranty.
