The Steelcase series 2 chair has technology featuring an innovative geometric design that flexes in two dimensions, supporting each part of your spine for responsive, personalized comfort and fit. The tilt mechanism is synchronized; the seat and back work in harmony with each other, keeping the body securely supported in the chair and feet firmly planted on the floor so you can recline without leaving your optimal zone for seeing and reaching your work. This model includes an adjustable seat depth, fully adjustable arms (raise up and down, pivot in and out, shift forward and back and side to side), pneumatic seat height adjustment, recline tension adjustment, flexing plastic mesh back, and upholstered seat. The seat features strong yet pliable foam which conforms to the body and creates pressure-free comfort. Flexible seat edge offers a bit of bend, right where you need it – relieving pressure points under your thighs. This chair will arrive unassembled and require some assembly covered by the Steelcase warranty.
