Summit is the only stand for me. It is so comfortable and solid in a tree, there is no give or wiggle at all.
Beaux, putting them together is a puzzle until you get it down. Tell him to stand up the seat on the cables and lay the cushion back opposite the cable. Then slide the base down into the seat, the carry straps attached to the base will pull through the seat, strap on the cushion for padding and you off.
