The assembly is self-explanatory and takes just 2 hours. However: Why the upper rods are screwed in addition to the lower and not leave your merge is questionable. The plastic piece between the bars is broken me everywhere. When hardware store had no corresponding intermediate pieces ... I got the idea to instead use a rubber gasket from the plumbing. This works very well. The top rods are slotted together, therefore everything seems a little shaky. I think it would be great to have the rods as a whole and to be screwed into each other. And it is in 2 separate packages to deliver.
