"And Murdy, is the backrest cushion that you put on the tree comfortable enough for a day long sit?"
I have not used the backrest, and I'm not even sure if my earlier models came with one. I usually hunt half days, and I flip the seat up and stand more than half the time. And I do usually bring my turkey hunting seat cushion along. I was in Gander today, and as far as a comfortable seat goes, that cloth seat on the River's Edge looks hard to beat.
