simple model cycles render subdivision based modeling 6129 quads 12376 tris.
P.S. i use renderfram to render openexr and that raw file i tonemaped and color corrected in blender. i dont know why but if just press render image looks very overexposure.
Very beautyful setup. Took me a moment to get the actual chair from your blendfile, though. Naming conventions are a little erratic maybe? :) But I appended the group in a new file and there it was. Thank you.
