Can you identify this lounge chair?  

Well, with swept arms like these...
the only models I saw were either Hvidt as a designer, or Mogens Kold as a maker.
(See me recent post where I was looking for the designer of a Mogens Kold sofa).
But the details do not exactly match these 2 references.
Maybe a true expert here will give you a better clue.

Here is one model of Hvidt/Möllgård-Nielsen
The sweep of the arms are pretty close. Here is one model of a Peder Hvidt / Möllgård-Nielsen chair you can compare with.
You can see the difference in the back pretty clearly. I have never seen the kind of ornamentation on the back of your chair on their chairs. Their stuff is pretty clean and spare. I don't think it is them and can't think of many others that I associate those arms with.

Ornamentation of the spindles in the back
Looks more American or British.
Where are you located?

Back
looks distinctly American to me

What kind of wood?
Is it made of? It does not look like teak to me. Maybe walnut. Or maybe a light wood with a dark stain.

More details
Thanks for all of the replies. I'm in the United States, and the seller said that she bought the chair from the original owner in Texas, who had it for most of her life.
I'm guessing that the wood is walnut. The curved arms are laminated, and the rest is solid. The finish looks like lacquer to me; it's glossy and has some subtle checking upon close inspection.
The joints where the arms meet the upper back are a little loose, and shining a light in the cracks reveals some metal hardware inside the joints. There are two wooden plugs on each side rail, the rest of the joints appear to be doweled with a sawtooth shape where surfaces mate.
I found this old eBay listing for a rocking chair clearly from the same maker. The finish looks similar, the eyelet motif on the back and the shape of the front rail are the same, along with the rubber straps and sawtooth-shaped joints. (link below images)

Found another one
My wife just found another one on Etsy. The seller claims that it's from Yugoslavia:

I guess the next step is to...
I guess the next step is to send the etsy seller a note asking why they believe it to be from Yugoslavia. If they send you a photo back of a "Made in Yugoslavia" stamp, then the mystery is solved.

Etsy chair
I'm waiting to hear back from the Etsy seller if theirs is marked "Yugoslavia". I didn't even know about Yugoslavian knockoffs until this morning.

Slavic Modern
It seems like every Yugoslavian made piece that I come across uses globe springs as seat support instead of rubber webbing.

"Knockoff" might be a bit...
"Knockoff" might be a bit harsh in this case; perhaps "inspired by the design of"? With the needle-eye backrest slats, I don't think this maker was trying to pass this chair off as another design.
And I can think of easier knockoff joints to make than finger joints, especially in areas that are not highly visible.

"needle-eye"
Oh my god...that term is perfect!
Thanks cdsilva.
ps lovely chair.

I agree
I think the chair has real merit on it's own, regardless of it's origins. I particularly like the later pictured rocker.
PS, the Yugo's were BIG on rockers. Many older ones that you see were made in Yugoslavia (for some reason) so if the pictured ROCKER and the OP chair are in fact by the same manufacturer? Yugo origins are very possible

Danish
I am going to be an optimist and speculate Danish. To me the construction seems right, by description it is a knock down and the frame detailing, especially at the front posts/ armrests seems better resolved than the Yugoslavian chairs I have seen. I would also say the wood is a medium stained beech which is fairly common in Danish export KD furniture. Just guessing though.
