To support the bench, I am thinking of using white oak cleats along the 3 supporting sides and screwing up through the cleats into the bench so that there are no (obviousy) visible fasteners
Would a running 3/4" x 2" cleat along 3 sides of the bench be sufficient to support the bench under easonable use? (say maximum of 3 adults or 4 children sitting on it).
Assume that the cleats will be screwed into the studs every 16 inches using a 3 1/2" deck screw. Assume also that 3" deck screws will be used to screw up through the cleat into the bench.
