Manufactured by Boss Office Products, the Boss Black Deluxe Posture Chair is made with a blue tweed fabric that also comes in red, black and gray. The chair is lightweight at just 23 pounds, yet still powerful enough to have a capacity of 250 pounds. Movement is not a problem with the five-star nylon base that has attached hooded double wheel casters. Although the unit has standard measurements of 25" W x 25" D x 35-40" H, it is completely customizable. Not only can users move the height up and down using the pneumatic gas lift, but they can also adjust the depth of the back. Perhaps the best features are the built-in lumbar support and waterfall seat design. Available for Online Purchase Only. Assembly required. This product ships direct from the manufacturer, so RC Willey Delivery is not available. Thick padded seat and back with built-in lumbar support Adjustable back depth
