My wife purchased 6 of these chairs. They are not "fine furniture" nor examples of "German engineering". They are good basic lounge chairs for a good price. They represent good value.The assembly is a bit tedious, having lots of bolts to tighten with the included hex key. After doing the first chair, I said "screw this" and purchased a set of hex key adapters for my socket set. I used the 4mm hex key socket with my 1/4" screwdriver handle to start the bolts, then the 1/4" drive ratchet handle to tighten. It was well worth it. I also used a 10mm box wrench instead of the included wrench. It made the assembly much quicker. Furniture assembly these days tends to use lots of hex keys, so the hex key socket set is probably a good investment anyway. For reference, I purchased this one which seemed to be reasonably priced and had good reviews. https://smile.amazon.com/gp/product/B004LE0XBC/Not all the holes aligned perfectly. Like I said, this isn't "German engineering". By keeping most of the bolts a bit loose until the end it is easier to get the alignment right. I used to included hex key a few times to align the holes as well.
