The top of my bench is 38" high, and was designed for standing, or sitting on a drafting chair/stool (they are a little bit higher). Single stage and progressive presses can be mounted right to the top of the bench.
Front of my bench overhangs by 5" so all the presses are mounted with bolts. It also allows sitting at the bench and your knees don't hit the selves or braces under the top. The overhang is not a problem strength wise because the top is a full 2" thick MDF, with the top sheet being maple veneer. Solid maple trims the ends of the top. The frame is square/rectangular steel tube, painted satin black.
BTW, the satin black, Flecto I think, leaves a fantastic finish on steel. The satin hides all little imperfections that would show if you used a gloss finish, but the finish isn't fully flat black. The black also sets off the wood top really nicely.
