We got a used version of this that someone already tried to put this together that didnt work. The bottom pieces a and c and b and c don't fit together.

I would not purchase this item! After spending an hour putting it together the last bolt holes were not drilled. So I had the entire thing built which was not easy because the other holes were slightly off and now I have a part of the chair you can’t put weight on because it has nothing supporting it. Target said I can return it but it’s huge! I’m not about to go into the store with it or take it apart! Huge waste of time! And a huge waste of money. Don’t purchase this chair!!!
