Identify a chair

Hi I came across this chair and was wondering if anyone knows the name of it! I think it might be a Horseshoe back chair but not too sure. Does anyone think they know the value of it too?

 

I've taken the liberty of reposting your photograph as Full Image so it's easier for everyone to see. (You'll want to remember to do that in the future.)

Horseshoe could do, but often "tub" and the configuration makes it a corner chair first and foremost. I'd say 20s/30s.
