New Office Chairs - B580 Ergonomic Mesh  Chair

The Boss Web chair is upholstered with a unique "Web" mesh material which allows air to pass through, adding to long-term comfort by preventing body heat and moisture build-up.
The "Web" back distributes weight evenly, and provides the perfect level of back support by conforming to each individual's back shape.
As with any fabric material, the "Web" mesh will stretch and loosen over extended periods of usage. That's why we invented the patented "Web Tension Knob". This allows the user to tighten or loosen the tension of the mesh material with a few simple twists. This unique feature you will find only on the Boss Web chair.
The seat surface and the outer back areas are beautifully upholstered with genuine leather.
Soft and durable molded polyurethane armrests.
The pneumatic lifter allows instant height-adjustment to fit user's needs.
The tilt -tension adjustment lets the user easily control the tilt resistance felt when leaning back.
Adjustable armrest allows each arm to be height-adjusted independently easily.
