Smaller chair but with good lumbar support?

[GSXRMovistar]

I'm in need of a new office chair for my office where I could be in it upto 8-10 hours on a busy day (breaks taken).

I like the style/look of all the recent gaming chairs but do any of the smaller chairs (I'm not a huge lad) offer lunar support control? I.e something the size of a Noble Epic compared to the Hero.

Thanks for any pointers.
