One piece folding Bench and Picnic Table
Step 7. Brace the rear seat
Turn the table upside down and prop or sit the rear seat on something solid. Ensure that the seat side-frame and the seat are at right angles to each other and fix the braces in place. Just like in the picture.
Flip the folding table up the right way and see how it works. Make any necessary adjustments as described in point 3 on page 7.
