Oqonos Cherg 022 Ergonomic Office Chair with Adjustable Neck Headrest, Self-Balancing Mechanism, 4D Armrests, Sliding Seat and

The Cherg 022 is designed for those who want to sit down and forget about adjustments. Its self-balancing mechanism detects the user's weight and adapts the recline tension automatically, with no need to turn any wheel or search for the right position. The seat uses honeycomb-structure foam that offers a feeling of high elasticity from the very first moment, maintaining firm support without losing comfort. The 4D armrests adjust in height, angle and depth with an extra-wide 110 mm pad that neither moves nor works loose. The high backrest, with lumbar curvature built into its design, is especially suited to taller people. It incorporates a height-adjustable cervical headrest with 90 mm of travel. The seat slides (50 mm) to adapt the depth to each user. The 60 mm silicone wheels protect any type of floor. BIFMA and EN1335 certified, with REACH certification. Maximum capacity of 150 kg.
