So I'm a 6'1" guy and weigh 180 pounds. I have the bar on the highest setting and it's very steady. Assembly could have been a bit easier though. The parts are packed as individually as possible in the large, somewhat heavy box they came in, and the bolts, nuts, and washers are packed on a labeled cardboard flap with tape all over the top covering them. You get two thin open wrenches to do the job (1 to hold the bolt head and 1 to turn the nut). Theres 20 bolts to put through slots. The instruction manual wasn't done very well but it was enough. Took me a little over an hour, maybe 90 mins with distractions, to build it. I used all the parts and tightened everything as hard as I could make it. (Don't tighten these until all bolts are in place with their nuts loose, or you'll have to backtrack, loosen, adjust, then re-tighten.)Using it is much better than I first thought. There's plenty of height room for me, my hands aren't limited by the frame, my knees can bend forward (legs crossed) during a pullup without hitting the backrest crossbar, and it doesn't wobble at all. It won't scuff your floor because of the plastic covers on the bottom, and it drags along really easily. The black metal and the many silver bolts make it look good. The padding for the hands' contact points are soft enough with a good grip. Glad I got it.
