Support Leg Installation
1. Remove the sofa unit from the HappiJac Bedlift and lay it flat face-down in a clean area.
2. The support legs can be adjusted, if needed. The 14-inch legs are normally are installed on the seat
cushion and the backrest uses the 15-inch. The legs can be adjusted by removing the two nuts and bolts
(Fig. 3A) and sliding the bottom part of the leg (Fig. 3B) in or out. Replace nuts and bolts after adjustment.
3. Measure about 12 inches from the outside edge of the cushion portion of the unit (Fig. 4). Feel for
strapping under the fabric and make a small mark between two straps that is close to both the 12-inch
measurement and to the inside edge of the steel frame. Repeat for the other side.

leg to one of the side holes (Fig. 5B) in the bracket.

6. Repeat steps 4 and 5 on the other side and make sure the end of the legs do not overlap one over the other.
7. Keeping the brackets in the same position, press the adjustment button (Fig. 5A) and rotate one of the
legs to make sure it does not stick out beyond the seat cushion hinge when in the stored position. Repeat
for the other leg.
8. Make a small cut into the fabric, just beyond the inside edge the frame. The hole should be large
enough to accommodate the bracket tab (Fig. 5C). Slide the tab into the cut slot so that support leg
bracket is upright and the arms of the bracket (Fig. 6A) are resting on the seat frame.

11. Find a centerpoint on the seatback between the two cushion leg brackets (Fig. 7A). Make a mark at that
point that is between the straps under the fabric and is close to the inside edge of the frame.
