I have a number of hunting chairs, including two original Double Bull blind chairs, one that has a blind you pull over you, a turkey hunting seat with a stadium seat strapped to it, and any number of cushions/turkey vests with cushions attached.
Here is one I just bought:
http://www.amazon.com/Shappell-STC360-ATC-Trail-Chair-Camo/dp/B00CJJBBL2
I bought it for four reasons:
It is light, like 3.5#
It has a back; a must for me for medical reasons.
The leg heights adjust individually. There is not much flat ground where I live.
It swivels. Very convenient when predator hunting.
I realize this is no heavy duty extended use item, but I only weigh 130#, and it will only receive occasional use. The wide footpads that won't sink in mud are a bonus. It is very important that any chair I buy be lightweight, preferably under 4# as I am disabled and cannot carry a lot of weight.
The only thing that would be better is a chair like this of slightly better quality (and weight) with a trigger stick-like lever that you squeeze once and all three legs adjust at the same time (even it you had to do it while not sitting on it). Primos-are you listening? Marketing opportunity hint hint.
