Make up the two back seat side-frames.
Assemble both back seat side-frames as shown in the photo and as per plan below.
Fix horizontal pieces [d] and [e] to pieces [b] and [c] with screws and exterior wood glue. Use 2 screws per meeting. Pre-drill the screw holes through the horizontal pieces.
The frames must mirror one another as shown in the picture. Take note (from the picture) of which side (of piece [e]) the starter hole is on.
Ensure that the bottoms of pieces [b] and [c] and the horizontal pieces [d] and [e] are parallel.
