Boss Web Task Chair B580
The B580 Boss Web Chair is upholstered with a unique "Web" mesh material which allows air to pass through, increasing 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 the tension over extended periods of usage. That's why Boss has invented the patented "Web Tension Knob". This knob (located underneath the seat) allows the user to tighten or loosen the tension of the mesh material with a few simple twists. This is a unique feature you will find only on the Boss Web Chair.
The seat surface and the outer back areas are upholstered with genuine LeatherPlus.
