I have a standard KR2S. I agree with all about the narrow hip space, but as I am not a large person (68" 180lbs) I haven't run into trouble yet with width. When I bought it it was a little tight in the headroom area, but we tilted the seat back some by moving the top seat supports about 3 inches aft. This gave me more than enough headroom, and somehow resulted in more knee to panel clearance also. Not to mention the original more vertical seat got uncomfortable on the back after an hour and a half. I did numerous 3 hour legs flying from Georgia to Washington State, and was very comfortable with the new, slightly more reclined, position. It's easy to suit yourself.

Moving the seat bottom down to the base of the aft spar or raising the turtledeck are 2 ways around this.
