Your weight does matter, to work properly there is some setup and balancing that needs to be done. Your height will determine how comfortable you are in it. the position your seat needs to be on the frame along with your weight will affect the balance and setup.

If you look for DOF Reality’s YouTube channel it contains some instructional videos on assembly that might give you a better idea of what the setup would look like.
