C40BL – Treston Plus 40 task chair, black fabric

Ergonomic task chair for prolonged sitting in industrial and technical work environments. Treston Plus C40BL is particularly suitable for product development, quality control and assembly, where work requires precision and static working postures. The ergonomic design supports the body’s natural posture and helps reduce strain on the back and shoulders throughout the working day. The fabric upholstery provides a comfortable seating surface for long-term use. The seat height adjustment range is 450–600 mm, and the chair also features seat depth adjustment, seat tilt and backrest height adjustment, enabling individual ergonomics. The synchronous mechanism supports body movement and activates sitting, while the adjustable backrest resistance adds seating comfort. The chair is equipped with soft twin castors (Ø 50 mm) that brake when unloaded, increasing safety by keeping the chair in place when not in use. Multi-adjustable 4D armrests (ARE) are available as an accessory.
