I found a camoflauge foam pad 14x14 at Sportsmans Wharehouse it has a velcro strap that I attach to my call bag for carrying into the stand. They might still have them, if anyone is interested.
I tried useing a small stool for awhile. Much more comfortable to sit on for shure, but I found myself moving around alot more when calling, picking up rifle, ect. Now I'm back to sitting my butt on the cold wet groung leaning up against a tree.
Got about 5 of these years ago when they were on clearance at Wal-Mart for $4 apiece. Cover with burlap, sew thw side straps closer to the seat for the best back support, and attach another snap at the end of the side straps for hands-free carry and doubles as a 3/4 shooting mat--
