Packaging, shipping, delivery in the usual good quality. The structure took about 30 minutes. The somewhat scarce instructions, have noted many other reviewers. I have the image of the chair considers the Internet to be able to grow the right way up armrests can, because that is not specified in the instructions. Then he stood there ready!
The basic settings in the beginning are simple and varied. You sit (nice hard) comfortable. The downside: It has been said many times, but I have to say it to justify my vote - the armrests. You are not adjustable (indicated in the product description it) and too deep. This meant that the Commissioner for Health and Safety, who has visited my workplace, has this rated as inadequate. To sit ergonomically correct, the armrests and the desk at a height must be so that you can write free of tension with applied arms. This is not possible with this chair. The classification to be able to work eight hours sitting it can relate only to the pure seats. Who wants to sit ergonomically correct needs to invest more and requires adjustable armrests or randomly so arranged armrests that they are in proportion to body size and the desk.
I also made the cross-check with a chair properly adjusted. It's true, you sit worlds better and more relaxed. Who wants to sit ergonomically correct and / or (like me) has an employer who also examines the establishment of the home office, should keep his hands off the chair. For short typing the chair is certainly in order. But as a full workstation chair he is unsuitable.
