My current benches are 40 inches high which make them perfect for me to load either standing or sitting on a high padded breakfast bar type chair.
I don't use a strong mount on any of my presses since the bench height and construction design negate the need for it. They are pretty cool but I just don't need them.
Wait a minute... aren't you a contractor? What the hell are you doing asking about buying benches... go buy some materials and custom build your own. Good grief... people hire you to do stuff like that!
It ain't a dialysis machine... no one is gonna live or die if it isn't perfect... we'll just make fun of you.
