HZ-ST-625 cantilever PP chairs with ergonomic shells on C-tube steel frames

— HZ-ST-625

Cantilever PP chair
ergonomic shell

The HZ-ST-625 is a cantilever student chair with a one-piece polypropylene shell on a springy C-tube steel frame. The contoured seat and waterfall back flex under the sitter, while the cantilever frame gives a gentle bounce that suits restless classrooms. An oval cutout in the back doubles as a grab handle, and with no rear legs the floor sweeps clear underneath. Moulded in a full range of shell colours on a silver or colour-matched frame.

— Engineering highlights

A little give in every seat.

— 01

Cantilever flex frame

The C-tube frame has no rear legs, so it springs gently as pupils shift and lean — comfortable for long lessons and easy to mop under at the end of the day.

— 02

One-piece ergonomic shell

A 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.

— 03

Oval grab handle

A moulded cutout in the upper back makes the chair easy to carry and to hang on a desk hook for cleaning, and adds a little ventilation behind the back.

— 04

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.
