When assembling has been noticed that some of the boards were slightly bent. I have yet ventured to the assembly - but was on the screws properly train, so that one of the screws when screwing is unfortunately around turned. Now I could turn out, nor more purely screws. A returning was therefore not possible. Meanwhile, I have along with Amazon found an alternative solution for this, thank you at this point!
The step stool is absolutely tip-resistant and looks chic. There he stands with us on a rug he also does not slide. Otherwise I would have organized "slidestoppers". The top level is in my opinion a bit narrow but still goes fine. With the acquisition, we are satisfied.
