How to Install Office Chair:

Step 1 Attach casters and gas lift to base .

1)There are five casters that fit into the base of the chair. It takes a bit of pressure to pop them into place. Be careful not to pinch your hand if the wheels move.

2)The gas lift just sets right into the top side of the base, simple as pie.

Step 2 Attach seat plate and armrest to seat.

1)You take the seat plate and line up the holes on the underside of the seat, and screw in four (4) bolts. Both the seat bottom and the seat plate are marked with FRONT, so just make sure they match.

2)Attach the right armrest — which is the more difficult side, for the tilt mechanism is slightly in the way — with three (3) bolts.

3)Next, attach the left armrest, also with three (3) bolts.

Step3  Attach seat back to seat bottom

The backrest is attached with four (4) bolts, two directly into the seat and the other two through the seat plate and then into the seat.
