I shot three games in a row at the California State Basketball championships last Sunday in Sacramento. We had to shoot from the baseline. I used a "ALPS Mountaineering Explorer +XT Seat" chair which has a nice thick pad on it and it worked great. I shot with 3 bodies and it worked out great. Easy to get to each body and saved my knees.
