Treston Ergo 25 Task Chair, PU ESD, High Model

Static-safe ergonomic support at standing-height workstations. The Treston Ergo 25 is an ESD task chair purpose-built for high workbenches and EPA areas, where work is often performed partly standing. Compliant with IEC 61340-5-1, it's approved for use in electrostatic protected areas – ideal for assembly and testing. A foot ring and conductive glides add stability and safety at height, while hard-wearing polyurethane upholstery keeps cleaning quick and easy.

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. Quick-set controls mean every operator can dial in their ideal position in seconds – perfect for shared workstations.
