Haven't a clue which designer or manufacturer this is from, sorry, but I do think it's a very nice chair.
Good luck with finding its origins.

Wow rinqreation, thank you for these links! 1stdibs has some that land SO close to the look. I at least can firmly plant this in the lounge/armchair.

It feels like it's the offspring of these two:

Ok, I think it HAS to be a Milo Baughman. Hoping it's an original. =p

Club chair or lounge chair. I've seen it before, but can't recall..

Could be, but could also be very vintage IKEA ;)

I love the chair but haven't a clue what company made it without so sort of marking. It is a MCM piece. Without markings it may be a knock-off. of a designer piece.

I'm ok with it being a knock off =) Either way, It's heavy as hell...and doesn't seem to cut corners on the design front (like many knock-offs seem to do). I'll see if I can track down some sort of marking tonight...maybe in a place I haven't looked.

@rinqreation Hah wouldn't that be hilarious...vintage IKEA. I'm ok with that as well =)
