Treston Ergo 25 Task Chair, Black Polyurethane, High

Ergonomic support built for standing-height workstations. The Treston Ergo 25 is a task chair purpose-built for high workbenches and varying working postures, where work is often performed partly standing. Particularly well suited to production and assembly, it combines a supportive contact backrest with a foot ring and glides for stability at height – and hard-wearing polyurethane upholstery that resists wear and chemicals and wipes clean in seconds.

Why choose the Treston Ergo 25 high model?

This chair is engineered for the unique demands of elevated workstations. The contact backrest mechanism maintains back support even in forward-leaning postures common in assembly work, and the seat tilt lets you sit close to the task while reducing strain on the lower back. The integrated foot ring provides secure support for the legs at standing height, and the wipe-clean polyurethane seat stands up to heavy use and chemical exposure. Quick-set controls mean every operator can dial in their ideal position in seconds – perfect for shared workstations.
