The bookcase looks great, but putting it together has been maddening. Every little jiggle makes the assembled parts start to fall apart again. I assume that somehow getting the back panels stably on and screwed into the bottom part of the frame will help keep it together. At the moment I am hoping that, anyway. It seems to me highly likely that when we lift it up something will jiggle out of place and send it all crashing to the floor. I certainly won't purchase furniture to assemble myself again!
