Treston Flex 19 Sit-Stand Chair, Black Polyurethane

Ergonomic sit-stand support for active workstations

The Treston Flex 19 Sit-Stand Chair in black polyurethane (product code C19PU) is designed for workstations where the job is done mainly standing, or by alternating between sitting and standing. It's a natural fit for production, assembly and intralogistics, where work demands movement and frequent changes in posture, giving operators a place to rest without stepping away from the task.

Relief for long periods on your feet

Standing all shift puts real strain on the lower limbs. The Flex 19 seat provides light support for the body and eases that load, letting operators lean and recover while staying at standing height. The soft polyurethane upholstery is highly resistant to wear, stands up to heavy daily use and wipes clean in moments for simple maintenance.

Free movement at the workstation

A 360° rotating seat lets operators turn smoothly to reach tools, components and tasks without twisting or repositioning. Combined with an easy height adjustment range of 510–780 mm, the Flex 19 adapts quickly to different users and bench heights for fluid sit-stand working.

Stable and secure at elevated heights

Sitting high calls for solid support. The integrated foot ring gives operators a comfortable, secure place to rest their feet, while the glides keep the chair firmly planted to boost comfort and safety. Prefer a mobile setup? The glides can be safely swapped for CSTOP castors that brake under load, holding the chair in place the moment weight is applied.
