Herman Miller Cosm Adjustable Arm Chairs

Precision Support: Why Choose Height-Adjustable Cosm Arms?

For individuals who shift between varying desk heights, sit-stand workstations, or multiple keyboard setups, the Herman Miller Cosm with height-adjustable arms offers the ultimate flexibility. By letting you tailor forearm height independently, it relieves stress from your neck, shoulders, and upper back during extended work sessions.

Key Features & Ergonomic Performance

Vertical Height Adjustment: Smooth vertical motion allows you to raise or lower the arm pads to align perfectly parallel with your desktop or keyboard tray.

Auto-Harmonic Self-Calibrating Tilt: The central mechanical gearbox detects your body mass to instantly provide balanced recline resistance without manual tension knobs.

Continuous Intercept Suspension Mesh: Breathable elastomeric mesh forms a supportive, pressure-relieving seat and backrest that stays cool throughout long days.

Cohesive Dipped-in-Colour Aesthetic: The arm assembly and adjustment controls are color-matched to the frame, mesh, and base in single-tone finishes like Graphite, Carbon, Mineral, Nightfall, Glacier, and Canyon.
