Make a wish! The Genie Task Chair has everything you could wish for. This unique design features a narrow upper back, which provides support through the entire back while allowing flexibility to stretch. This chair has a height adjustable seat. Height and width adjustable arms move with the touch of a button. A tension knob underneath the seat allows the user adjust the resistance of the reclining motion. A lever allows the user to lock the chair in a reclined position or an upright position. A mesh back increases breathability and molds to the back to provide comfort and support. Choose from several color options. An optional polished aluminum base creates an executive look. Optional hard floor castors have a rubberized finish, creating a smoother and quieter rolling experience on hard surfaces.
