Treston Ergo 20 Task Chair, Black Polyurethane

Ergonomic industrial task chair built for precision work

The Treston Ergo 20 Task Chair in black polyurethane (product code C20PU) is engineered for demanding industrial environments where the work calls for accuracy and frequent changes in posture. Designed for assembly, production and maintenance settings, it keeps operators comfortable and well-supported through long shifts and varied tasks.

Hard-wearing, easy-clean polyurethane upholstery

The seat and backrest are finished in durable polyurethane that stands up to heavy daily use, resists chemicals and shrugs off wear. The smooth surface wipes clean in seconds, making the Ergo 20 an ideal choice for workshops, cleanroom-adjacent areas and any setting where hygiene and low maintenance matter.

Posture support that follows the way you work

A contact backrest mechanism maintains support even when you lean forward, exactly the position needed for close assembly and detailed bench work. The seat tilt function lets you angle the chair toward the task, helping you sit closer to your work while reducing strain on the lower back. Together these features encourage a healthier working posture throughout the day.

Quick, tool-free adjustment for shared workstations

Every key setting adjusts fast and intuitively:

• Seat height adjustment: 440–620 mm range to suit a wide variety of users and bench heights
• Seat tilt adjustment for working close to the task
• Backrest height adjustment for tailored lumbar positioning

Because the controls are so simple to operate, the Ergo 20 is perfect for shared or multi-shift workstations where the chair needs to be reset for the next user in moments.

Safety-focused castors

The chair rolls on soft twin castors (Ø 50 mm) with load-sensitive brakes. When no one is sitting on the chair, the castors automatically lock to hold it in place, reducing the risk of it rolling away and improving safety on the shop floor.

Optional 4D armrests

Multi-adjustable 4D armrests (accessory code ARE) are available separately. They help relieve strain on the arms and shoulders during repetitive or extended tasks, and adjust in four directions for a precise fit.
