Not very durable

I have the chair now for two weeks in the (permanent) use. I am pleasantly surprised, because I did not expect that he looks so good and makes such a strong impression. Much-quality and more comfortable than my old executive chair, who was then more expensive.
Strong buy recommendation.

Addendum 14.07.2014:
Now, after several months of chair still looks great and is absolutely stable. Since several buyers had criticized quality problems, I am amazed at my somewhat. Have zero problems, and he is extremely comfortable!

Addendum 30.12.2014:
Cheered too soon; Even my lift no longer keeps me really. After less than a year I have to now ask for a replacement part.

Addendum 09.02.2015:
Had the chair unfortunately complaint and have since taken on a new one. It seems that the quality is now better. However, some screws are still not quite right. I hope the elevator now holds more than a few months.
Next time I will probably choose a more expensive model.

But 5 star for Amazon and the uncomplicated handling!
