This is a contemporary ergonomic executive computer chair. It is faced in soft A-Grade top grain leather and features a medium-height backrest. The backrest recline motion is synchronised 2:1, which means that the seat only rises slightly as you recline into the backrest. This ensures that your feet can stay firmly on the ground through the movement. The backrest can be locked in many recline positions. The world is open for business and you are in the driving seat. A great chair for computer, home and office use. CHAIR STABILITY Stability is provided by a large polished chrome 5-star base. SEAT HEIGHT ADJUSTMENT Adjust the height of the seat with a single touch via a pneumatic gas-lift which also allows the seat to swivel smoothly. LOCKABLE SYNCHRONISED RECLINE Recline the chair at a tension that is adjustable to suit your individual body weight. Use the chair in 'free-float', lock it in any recline position, or lock it in the upright seated position. When you recline the chair, the backrest moves at twice the angle of the seat so that your feet can stay firmly on the ground as you lean back into the recline.
