I like this design. I used it as inspiration for my folding workbench. Mine uses floating supports though so no legs actually touch the ground. Its still very sturdy though. Check out the details at my blog at http://www.justmeasuringup.com/blog/building-…

I also beveled the edges for a nice finish and used small gate bolts to lock the swinging legs into place (in case i accidentally knocked one in with my leg)
