Search For An Office Chair

There's one corner of our house that hasn't really been touched since we moved in is a little office corner where Kyle has his desk.  It's a mish-mosh of a beautiful old midcentury desk made of dark wood, a vintage tall wood file cabinet in light wood, a vintage industrial cart-shelf and a large red velvet desk chair.  It's all vintage, but the pieces don't belong together at all.  The worst of it is the desk chair.  I like the lines, but that's about it.  I'm not sure what I was thinking.  Red is not a color anywhere in our house and it's too big to fit under the desk, so that is the first place I want to start when I tackle this mini makeover.  Here are my picks for a new desk chair option.   Which do you like?  Think I'm leaning toward option 2, the wood is not a predominate detail, so it's not fighting the other pieces, and the white will lighten up the dark wood desk.
