The notice is certainly minimalist (and this is nothing to say it!), But if you correctly follow the diagrams and especially when mounting order mark indicated by numbers in circles, then the assembly goes without evil . Provide still a flat key and a key to better pipe bills that small keys included ... Once mounted, the chairs were frankly "the mouth", they are very comfortable, the case is an eye adjustable headrests and make their office blink. A purchase to recommend!
