Thanks for the info. I've had zero luck finding anything other than this photo from the George Nelson Foundation. I'm well aware of the rules for the forum with regards to valuation. That being said, there are just no examples out there that I can find. I'm also aware that rarity and collectibility are not one and the same. Do these things have any value? I left it at the store with a $35 price tag on it, as even though I had a strong suspicion it was HM, it was just not appealing to me.

I prob would have gotten it, but I passed on one as well as there is nothing on them and you don't see them listed for sale much if at all

It is a quiet design sold in conjunction with HM's Action Office 2 contract furniture system and if used in the right setting, it should be fine like those "fill-in" pieces designed by Florence Knoll. Too much statement pedigreed pieces in a small space will cancel each other out.
For $35, it is a better alternative to buying one of those pricey and trendy but short lived inferior pieces mass produced during the last 3 decades. The value is not much on the rarity/collectibility but on buying a well made office chair that lasts and only once in one's lifetime.

Well, I went back and scooped it up. I'm not in love with it, but could not let it go at that price. We'll see what I end up doing with it.

Damn good decision ZooMob.
It looks to be in decent shape, and the textile is acceptable. Well built, too.

I like it, and at $35 I would have bought it too...

Good for you ZooMob. You can also make it look less contract furniture/desk chair looking by removing the castors/wheels and replacing them with glides and lowering the seat to a lounge chair height. That's what I did with my $3.50 Knoll CEO chair by Vincent Cafeiro on split walnut base. At the time, it was safer for the little kids when they discovered early on that some of our chairs can turn 360 deg and roll across the room like an amusement park ride.
And save the wheels for later use if you want to turn it into a rolling office chair again.
