So the chair fell to the floor during a move, and the back rest got detached. I think that wooden cube part was probably originally nailed to the back seat first, and then glued to the where it's shown. I have no clue on anything related to woodworking, so not sure what the parts or tools needed are called, and how to detach the glued part without damaging it. Any tips would be highly appreciated! Thanks.
