The assembly, the fixation of the items on the tubes, the screw and the final adjustment, or setting up the wardrobe is more difficult than we thought. Either the left is wrong or the right side or on the ceiling a small gap, so that again the rubber ring has to be rolled deeper.
The manufacturer should equip your feet instead of black rubber with white rubber. Because then you have black stripes on the ceiling if you're not careful. Is best to take a second person on hand. The spouse better not, because that degenerates in the dispute, because it does not fit the back and front right away and everyone wants to have rights. I would again do not order this shaky system. It's better than nothing, but nothing more.
