Very poor design, the metal frames are supposed to fit into each other but when the item arrived the frame was badly warped in the edges where they are supposed to fit that it was impossible for the pieces to come together. The only way was to forcefully bend the metal to make it fit (which results in some of the pieces breaking apart). It was either that or attempt to return all the heavy pieces.  Extremely disappointed with this purchase. I’m not even sure this is going to last long because the warped areas are part of the post that supports it.
