Step 21: Install the Leg Extension
Locate the following items:
• Item #18 - Lock Knob
• Item #19 - Leg Extension Assembly
Remove the Seat (installed in Step 10), and turn it cushion
side down. Insert the Leg Extension Assembly (Item #19)
into the open end of the Seat Backbone (Item #17).
Line up one of the holes from the Leg Extension with the
hole in the Backbone, and screw the Lock Knob (Item #18)
into the hole on the Seat Backbone, as shown in Figure 21.
Re-attach the Seat to the Seat Backbone (see Step 10).
Note: You may adjust the Seat for your height once the

Step 22: Install the Leg Extension Rollers
Locate the following items:
• Item #20 - (2) Chrome Roller Tubes
• Item #21 - (4) Foam Rollers
• Item #22 - (4) Foam Roller End Caps
Insert the Chrome Roller Tubes (Item #20) through the
upper hole and one of the lower holes of the Leg Extension

shin.
Slide the Foam Rollers (Item #21) onto the ends of both
Tubes, then secure each Roller with an End Cap (Item #22).
Note: You may need to use a Rubber Mallet to fully insert
the End Caps into the Tube ends.
