Oqonos Cherg 028 Ergonomic Office Chair with Elastic Mesh Backrest and Seat, Self-Balancing Mechanism, 4D Armrests, Sliding

The Cherg 028 is Oqonos' bet on a design refined to the maximum: backrest and seat made entirely of high-performance elastic mesh, with no foam, no headrest and no added lumbar support. The result is a chair that offers total ventilation, freedom of movement and a clean visual profile. But minimalism does not mean a lack of features: the self-balancing mechanism with cable control adapts to the user's weight without manual intervention and lets you adjust the chair without bending down, with 3 locking positions. The 4D armrests adjust in height, angle and depth, and the seat slides (50 mm) to adapt the depth. The backrest is the tallest in the whole range (700 mm) and the chair reaches 700 mm in width, offering generous support without restrictions. The recline range of 93° to 128° is also the widest in the Cherg series. The 60 mm silicone wheels protect any type of floor. BIFMA and EN1335 certified, with REACH certification. Maximum capacity of 150 kg.
