As we were assembling this piece of furniture a section of it just fell to the floor while it was standing up and no one was touching it. It ripped the screws and dowels out of the holes and tore pieces in the wood while also stripping the threads of some of the screws and snapping some of the dowels into multiple pieces. We were working on another piece of the bookcase and heard a snapping sound right before seeing part of what we had just assembled crash to the floor. We purchased the protection plan with the piece of furniture and will be requesting a replacement!
