I am 6ft and this bench is a little bit too short. When the back is upright all the way the back only reaches to the top of my shoulder blades. At a 45 degree angle it reaches to behind my ears. When all the way back it just supports my head.
The pads are only secured by 2 average size screws that you have to really tighten to prevent any wobbling.
Finally the wheels are a tab too high up to wheel around comfortably without lifting it up almost 60 degrees from the floor.
Other than those issues you can really adjust the back angle from around 12 different points from 0 degrees to 90 degrees. It feels real sturdy when lifting 200lb on it once you tighten the screws.
