Guys, I will back up NCRemingtons comments about the gunslinger treestands 100%. They are by far the most comfortable stands you will ever sit in. It is literally like strapping your lay-z-boy to the tree. About 5 years ago I use to work in a shop in Dothan Alabama that carried these treestands and we couldn't keep them in stock.
The back of the seat is adjustable so you can sit more upright or leaning back.
They also make one called the combow hunter that is a bit smaller and lighter in weight and you can either face the tree or face away from the tree.
