Treston Flex 19 Sit-Stand Chair, Black Polyurethane ESD

ESD-safe sit-stand support for sensitive electronics work

The Treston Flex 19 Sit-Stand Chair in black polyurethane (product code C19PU-ESD) is an ergonomic, ESD-protected perch designed for environments where sensitive electronic components are handled. It's especially well suited to assembly and production in EPA areas where operators work mainly standing, giving the body a place to rest without leaving the standing position.

Compliant for ESD-protected areas

Built to comply with IEC 61340-5-1, the Flex 19 is approved for use in ESD-protected areas (EPA). This high ESD version pairs conductive glides with a polished aluminium base to safely dissipate static charge, protecting the delicate components your team works with every day.

Comfort that supports prolonged standing

Long periods on your feet take their toll on the lower limbs. The Flex 19 seat supports the body and reduces that strain, letting operators lean and rest while staying at standing height. The soft polyurethane upholstery resists wear, stands up to heavy daily use and wipes clean in seconds for easy maintenance.

Smooth, intuitive movement

A 360° rotating seat lets operators turn freely to reach tools, components and tasks without twisting or repositioning. Easy-to-use height adjustment spans a generous 510–780 mm range, so the chair adapts quickly to different users and bench heights for seamless sit-stand working.

Stability and safety at elevated heights

When seated high, stability matters. The integrated foot ring gives operators a secure place to rest their feet, while the glides keep the chair firmly planted, improving both comfort and safety. If you prefer a mobile setup, the glides can be safely swapped for CSTOP-ESD castors that brake under load, holding the chair in place the moment weight is applied.
