Assembly takes a long time, and the pieces to not fit together well.  Furthermore, the screws are soft metal so the heads strip out easily.  The bottom step ladder comes out of the track and is difficult to reposition.  Also, unless the chair is sitting exactly right with the bottom  step stool positioned perfectly, the chair is unstable and out-of balance.  I will keep it since it took so much time to assemble and it is going in the garage, but I would not recommend it.
