I bought the chair for my home office because you can fold up the armrests and I can then push it under the rug. The delivery was flawless. All screws, the plan included everything. Very easy assembly, which could be managed with the supplied tool. Tilt function, up down, everything works. The metallic plastic looks like metallic plastic, but is bearable. The leatherette acts like quality vinyl, making it an ethical Stuhlbezugsvarante. About the advantages and disadvantages of various references you know all about it now. The chair is very wide and and should thus actually be any character justice, especially since one can fold away the arms. The seat itself but could be better cushioned. The support in the back is good and similar to modern car seats. The tilt function I emfinde rather unnecessary, but it is still quite enjoyable.
