This is my version of your outdoor bench. I added the extra 2×4 to the front seat of the bench but I also added arm rests. I made the legs the same size (25″) as your 2×4 chairs and added a shaped arm rest. One other modification was the 40 inch stretcher under the seat. I put it on the other side of the back rest so that I had a better shot at the pocket holes. Seemed to work fine. Really enjoy your videos ….
