CAUTION:
Be sure all cords and fingers are out of the way before
installing the backrest, to avoid damage or injury. You may want to
use two people for installation, as the backrest is heavy.
1. Attach the backrest to the chair base
Before installing the backrest, remove the two screw knobs from the bottom
of the backrest. Align the guides on the lower sides of the backrest with the
track on the chair base, then slide the backrest firmly onto the chair base.
From the bottom of the backrest, install and hand-tighten the two screw
knobs. Verify that the two screw knobs are installed and tightened before
using the chair.
