Solve My Puzzle With Hans Wegner Chair  

I've rewoven a bunch of those
and none were marked at all.
Yours does look like it was rewoven. It's not a bad job, just a little sloppy here and there. The original weaving would have no space between the wrapped cords along the front and back rail and there would be no overlapped cords like you see in your detail shot above.
It's possible to do a better job of weaving than that. I mean, it's not a lost art or anything. But it's really not bad. I've seen much worse!
Oh, and yes, your chair is real. At least as far as I know--no one has ever made knockoffs of these.

Also..
..it looks like the cord is a bigger diameter than was used on the originals. There should be a four-strand group on either side, not three-strand as yours has. And I see three strands of wrapped cord between each front-to-back double strand on the back rail and I think it's supposed to be four, if not five.
And in case that's not enough proof, there is a screw holding a loop of cord on the underside. Should be an upholstery tack and it should be up higher and not so visible from that angle.
WHEW, i'm boring even myself now...

Thank you Spanky
You did not bore me at all! Thank you for being articulate and thorough, it help me a great deal. Do you think it is worth it to re-rope these. Can I do it? I am good with my hands.

If you want them to look
authentic, then yes, it's worth it to redo them yourself. The price range I have heard to reweave these is from $150 to $400 (high was in NYC area, I think).
This is a harder one to weave because of the side patterns--they're not hard to do but it means that you have to use cut lengths of cord instead of pulling it off the spool as you go.
Check out the thread below. It's long but there is a lot of helpful information. If you like working with your hands, it's very satisfying to master this skill. A finished seat done well is so beautiful and useful!

Also
this is probably obvious, but clean and oil the wood before you start weaving the new seat. The paper cord is not treated with anything that will resist oil stains.

Thanks Again Spanky
Very Helpful link.

Christ...make that robert 1960!
He just looks a couple of years younger. And how could I forget fastfwd and tktoo??....I'm getting old. A big gold star (and a good bottle of vodka) wait for both of you!

Make that an XXL sparkling tiara, please. I have a giant head. (Not swollen, just one of those really big Scots-Irish skulls.)
I nominate Mark for Master of Ceremonies! For everything!
Also, bartender.

I was thinking of a simple tiara...
and you looking quite elegant next to an aqua range.
ps one size fits all....
