My seat will just about sit on the ground when I lower it fully, is it possible that you did not push the lever/button down? it is the same lever/button that moved the seat forward and aft. Maybe a wire is broken not letting the seat drop down? But yes to answer the question, the power seat does go up and down. Maybe contacting the seller to verify that the seat will go to the position you need, he should be able to tell you or show you again.
