Note: This chair is NOT fire retardant and can only be sold in the state of California if the building is equipped with a sprinkler system. • Standard Tilt • Fully Adjustable Arms • Non-upholstered Arm Pads • Size B • Adjustable lumbar support • Graphite base • Black • Carpet only casters • Pellicle Carbon fabric • Not Fire Retardant This chair has 3 sizes and a Pellicle® material that conforms to the user's body and retains its original shape when unoccupied. The material is lightweight and breathable and distributes the user's weight evenly over the seat and back of the chair. The chair has pneumatic height adjustment and a Kinemat® tilt that lets the body naturally pivot at the ankles, knees, and hips. Tilt options include a tilt limiter that allows the user to select the tilt range to limit the amount of recline; a tilt limiter and seat angle that allows the user to select the tilt range and a horizontal or 5° forward seat angle; or a standard tilt. Back-support options include PostureFit® support and an adjustable lumbar support. The PostureFit support provides a custom fit in the lower back area, below the beltline, that helps achieve healthier posture and improved lower back comfort. The user can adjust the level of support with a lever. Arm choices include a fixed, nonadjustable option; a height-adjustable option that moves the arms 4" vertically; and a fully adjustable option that moves the arms 4" vertically and pivots the armpads 15° outward and 17 1/2° inward. The ZB, WS, and G8 base/frame finishes include a frame applique. These appliques are applied to an Aeron work chair's seat, back, and arms to minimize the effect of contact between the chair and a wood-edge surface. The G8 option does not include an arm coating. The frame applique options (ZB, WS, and G8) do not meet CAL 133 requirements. Note: To help determine chair size, see Aeron Chair Size/Fit Reference in Appendices. A-, B-, and C-size chairs are tested and warranted for use by persons 300 pounds and under. Note: For information on casters and glides, see Casters and Glides in Appendices. Note: PostureFit support is not available on standard tilt option. Note: Customer's Own Leather (COL) can be applied to armpads; requires 4 square feet.
