Desk Chair Recommendations

[VitalSyntax]

I'm in the market for a new desk chair, I've got ~$200 to spend and would like something leather/pleather or mesh in black. I'm quite the large guy at 6ft 5in an 260lbs so I need something well built with lumbar support. Here are the 3 chairs I've narrowed it down too:

Basically if you could choose between these three chairs which one would you choose and why, or what other chair would you recommend for my specifications.

The first one looks like it would contour to my back the best, but it might not work well for you if you're really wide.

Probably the 3rd, but realistically none without first trying it out in person. Lumbar support adjuster is a must! Besides the regular height and seat section length adjustment. Skimping on the chair is as bad as buying a $1 bin fan and getting mad when it breaks. The best built computer is useless if you can't bear to use it due to ergo pains.

The 3rd one.

Bean bags are cool right?

I ended up getting one of these: http://www.amazon.com/Grain-Premium-Leather-Executive-Office/dp/B0081LC210/ref=pd_sxp_grid_i_0_1 (although it was on sale for $160 at Costco). Overall I'm extremely impressed with the build quality and the comfort level. It was a bit difficult to assemble but first impressions are quite high. Hopefully it won't fall apart on me.
