I hunt mostly flat brush country and you have to be up off the ground a bit in order to see. Have found this children's folding camp chair to be ideal; four legs instead of three (been dumped more than once when a stool leg breaks through into a gopher hole /ubbthreads/images/graemlins/angry-smiley-055.gif), lets you see over high grass/short bushes, short back helps shrink your aiming "wobble zone", still light enough to carry to the stand.

Getting comfortable while maintaining a solid shooting position is essential to success IMHO; never go afield without one.
