Where can I get modern high back chairs for sensible money?

[CSR Performance]

I'm looking for a couple of chairs for my office, but struggling to find anything. Modern design, but must be high/wing back. I like to rest my head against the back of the chair and the wings help dissipate any ambient noise.

Something along these lines:



Ideally on a swivel base but its not a deal breaker. I've only found commercial suppliers that have anything even vaguely close and they are about £1k each and usually with a minimum order quantity 2.

Nothing on the Ikea website, or in my local furniture shops, so any suggestions welcome.
