Step 4
Place frame on tabletop and attach remaining cleats in place with 2" screws and wood glue.
My coffee table needed additional support, so I purchased four L brackets in 4" length, and attached flat to the underside of the coffee table frame. This was sufficient. You could also add additonal cross bracing to the bottom (when in coffee table position).
