A flat pad if its wet, or nothing at all if its dry. Chairs are a pain to pack and in the course of a stand I may go from sitting to prone, or go from rifle to shotgun. If multiples come, there are too many scenarios where I may be shooting in any direction in a hurry. Also, not much cover here so you would stick out like a sore thumb sitting on a stool. I could see the elevation helping in the brush country, but not here.
