Chairs by Stendig, Looking for information and history on these. Thanks!  

There are plenty of information out there about your chairs.  Start with what you have - Stendig and Andover chairs, a quick google search with the information you have will give you that its was designed by Davis Allen of the architecture firm SOM (Skidmore Owens and Merrill).  Stendig was the original manufacturer and whent it went out of business, Knoll picked it up and became the current manufacturer.  It has been renamed the Exeter chair and is a standard issue for Knoll's contract projects.  I really liked the aesthetics of this chair, simple and quite elegant but the scale is a bit large and throne like for residential use (at least in my house) but it sits perfectly in any SOM high rise/skyscraper lobbies, conference rooms and CEO/upper and middle management offices..

So even the chairs with the plain black dust covers under them without the stendig name stiched in are also Andover. The underside of those just seemed less "finished", glossy finish is only where you can see it without turn the chair upside down unlike the others where the glossy finish covers every square inch of exposed wood? I did find information but was only by what I saw and kind of just wanted to see if someone knew why they were different. Only one chair out of all of them has the Andover sticker on it. Thank you for the reply didn't dig deep enough to hear about Davis Allen, appreciate it!

All your chairs were made by Stendig and all were known as the Andover chairs starting in 1983.  Your chairs with the Stendig dust cover (under the seat) were original to the chairs made by Stendig, the others with just the plain dust cover under were either re-upholstered by some one (not Stendig) in the past or if not, Stendig could have just used a plain fabric cover later in the production (?).  The different dust covers under your chairs does not make one authentic and the others not as real, you worry too much about the dust covers which are replaceable by anyone if the chairs need new upholstery.

All the chairs like yours made by Knoll (1990's) will have a Knoll label and are called the Exeter chairs.

Even the plain black dust covers still have the white "sold by Stendig" tags stapled to the black covers so unless they were meticulously removed and re-stapled in the exact same spot they are original. I was also wondering if the current upholstery on the cushion has a certain pattern or style? Trying to find something similar and all i could come up with is polka dot haha and it's not giving me the results I was looking for...

All you chairs are originals.  The best that you can do for all your chairs upholstery is to find a solid color plain weave wool or do it in leather, solid color vinyl will look great too.  Go to Knoll Textiles or Maharam or the other textile manufacturers websites online, you will most likely find the best material that suits and appeal to you.  Your chairs have an advantage that it has a simple square seat that you can actually look for remnants of the same material instead of buying and paying full retail price from a fabric bolt.

My inital thought what black non-textured leather, making the whole chair solid black?

That is a decision you have to make.  If you are selling them a a lot, sell them as found and let the new owners decide how to rehab them, if it is for your own use, don't just look at the upholstery but look for a material that goes well in context to the room you are using them.  Keeping it neutral is safe but if they are mine, I will find some vintage zebra hides.

I like that idea, I actually plan on selling 6 of the to pay for the 4 I keep.

Or at least try to, the places I see people selling them are asking prices that are prob 4x what someone would actually pay for them. Would trying to sell them for 200 each be out of line?

I worked for Stendig for several years and can verify that you've been given very good information.

Stendig had their own textile line, and this doesn't look like one of theirs.  Typically these chairs were upholstered in mohair or leather. As it was pointed out, David Allen was an architect at SOM,  a firm known for minimalism and its restrained design, but also of the higher quality. As a year has passed you have probably already resolved this situation.
