Designer?  

It doesn't matter- the chair looks to be of an pretty unexceptional "design" value.
However, it does appear to be reasonably constructed from quality materials in a manner that is likely to be perceived as comfortable by most. Therefore, it is probably best to focus more on say the fine deep caramel top-grain leather or the walnut (or whatever) arms, or the nice casters, etc. than the brand of the thing.
Brand recognition for furniture is generally very low, because it basically doesn't matter except as a means of differentiating price points. Every company just copies every other company, for the most part.

Objectworship, I kind of want to argue with your choice of words there... 'unexceptional "design" value' seems a little harsh, as the design looks to be very adequate for an executive 70s contemporary office setting, and actually looks to be quite on the posh side
Also I am not sure you can unequivocally say that it doesn't matter

Ah, I just meant I don't think it's a fancypants whosit for whatsit.
That's all subjective, though, huh?
I'm of the opinion that everything matters/does not matter simultaneously.

"Posh" is very different from "good design".
Sure the chair looks comfortable enough, but it is not a significant design, in the usual sense.
That is sometimes hard to hear, as we are all on the learning curve, developing our eye for such things.
I think Objectworship was trying to tell you in the nicest way possible, and was trying to help you sell it by stressing the chairs good points.
