Oqonos Cherg 017 Ergonomic Office Chair with Waterproof Fabric, Self-Balancing Mechanism, Adjustable Lumbar Support, Height

The Cherg 017 is the only chair in the Cherg range with waterproof fabric on the seat: resistant to water (grade 5), oils (grade 6) and wine (grade 5), with over 100,000 cycles of wear resistance.

Its self-balancing mechanism adapts automatically to the user's weight with no need to adjust the tension manually, and the cable control allows adjustments to be made without bending down. The lumbar support, with a breathable mesh surface, is height-adjustable to maintain cool, continuous support throughout the day. The 60 mm silicone wheels protect any type of floor.
