I enjoy watching my grandsons play baseball... I don't enjoy sitting on bleachers designed for people a tenth of my age. Last weekend I couldn't get out of the canvas and aluminum tube fold up camping style sling I'd been using. (Grrrrr...)
I had seen the fold-up wood patio chair in the "projects ready to go" section of the SB web site, and was intrigued. I don't know who's design the chair is, but it is well thought out and pleasing to look at. However, I wanted MY chair to be lightweight as I have to carry it from the parking lot to the diamond. The plans call for 3/4" exterior plywood... I didn't feel bad about substituting 1/2" Baltic birch for the legs. I suspect that the 1/2" BB is stronger than 3/4" exterior ply any day! I wasn't sure about my plan to substitute 1/4" BB for the 3/4" slats however... The 1/4" slats made it so that the tenons came through... that's OK if you consider it a design feature!
The 1/4" slats turned out to be VERY comfortable! They act like springs and mold to my back and butt, for anyone not familiar with Baltic Birch, Don't equate it with U.S. products. If I'd used H D 1/4" material, I'd be on the ground in a pile of rubble!
Version two will have the slats all radiused , the square corners are a little sharp.
