Remove any packing cardboard or plastic from the sofa. Take out the small pieces and place in neat piles within reach.
Put on the legs or feet for the sofa. Turn the main piece of the sofa upside down. Inspect the included feet and look for holes for installation on the bottom of the sofa. If not present, use a drill to match the included screws. Drill into the solid wood area on the underneath corners. Screw in the footing screw approximately halfway into the bottom of the sofa. Put the leg onto the screw and tighten into place.
Flip the main frame of the couch upright and install the pull-out mattress, if included. A metal bar or four brackets will be in place along the edge of the sofa. Align the back, or folding area, of the pull-out with these brackets or bars and screw in place.
If the sofa does not include a pull-out mattress, skip this step.
Put seating cushions in place. The back may be solid or require that two or more cushions be put in place. The sofa should come with two or three seating cushions which should fit tightly in place across the seating area.
