Grasp the bottom edge of the fabric or leather back panel, which you'll find near the bottom of the chair. Pull the panel toward you to release the hook and loop tape strip holding it in place. Fold the loose bottom edge of the back panel toward the top of the piece, and secure it to the fasteners at the top corners.
Slide your hands along the sides of the exposed back area, where the back meets the seat. Stop when you feel the release latches. Press the latches simultaneously.
Lift the back of the piece straight up and off in one smooth motion. Lift until the back is completely detached from the seat. Rest the detached back face-down on the arms of the chair, or the seat of the sofa, to box or move the piece.
