35 inches at the widest part of the rear, before cutting corners to a 3 in. radius. Front is 29 in. before rounding corners to a 5 in. radius. Tail is 12 in. wide with 3 in. radius, 15 inches in length. Height is 34 1/2 inches, perfect for being upright enuff( on a baseball bucket seat) that hard kickers aren't bad. Most portable benches are so low, that you have to kinda hunch over, letting the boomers really pound ya. Top is 1 1/8 inch OSB, sanded and poly'ed. The only thing I would change is cutting the rifle slots to be more balanced as carry handles. They're a bit too far forward, but well out of the way when in use. I used pipe floor flanges first(on tapered shims) for the legs. Not solid enuff to suit me. Rebuilt it with angleiron/leg socket frame similar to the Stuckey benches. It is a ROCK now........ Hope that helps. Don
