Can anyone tell me who designed this chair or where I can purchase it?

could be a Howard Keith.

Pearsell
possibly?

The base doesn't look like Pearsall---not Kaganesque enough.

At first
...I thought perhaps you worked for Lowes and were trying to broaden your advertising base.
However, assuming you are genuinely interested in finding out more about the chair design... I think it may be a contemporary piece styled to look vintage. It reminds me of a couple chairs I saw advertised recently by Elite Leather. One is called "Circa" the other "Mod".
It also reminds me of some of the "Reto" offerings by Room and Board.
I have to say that while not objectionable, I am not particularly impressed by the chair. Perhaps it's the upholstery that puts me off. It also looks poorly done. To have a bold pattern like that and then to have it not line up at a seam as it does on the back looks especially bad.

Thank you all
I appreciate your responses. I really liked the design of the chair......the upholstery was horrid but that could be remedied. Fingers crossed I'll find something similar.

I Think I Found one For You ....!

Slipping in an ad for your knock-off...?
FYI, IT IS NOT MY AD. However, your reply shows in what cesspool your mind is.

It may be a cesspool, but it...
It may be a cesspool, but it knows the difference between a lounge chair and a sofa.
