Office chair up up CH-193A Ergonomic design, adjustable height, swivel base

Advantages

The fixed headrest offers neck support without mechanical adjustment, while the one-lock mechanism secures the tilt position for stable seating. Anti-shock casters reduce impact when sitting down or moving the chair, and the 340 mm nylon base with a 100/4 gas lift ensures reliable height adjustment and stability.
