What I mean is, some climbers have a adjustment bracket on both sides of the foot platform, so if you are not totaly level you can remove a pin and slid the platform up or down to level it as you sit in the seat, and the same for the set, you can stand on the platform and move the set up or down to level. I would not recamend that type of climber, not to safe in my book. Always remember to wear a safty harnes..
