I have the Gobbler Lounger and it is very comfortable and the only chair I can sit dead still in for a long period. I have found 3 problems with it though, 1) it is a bit heavy to carry if you are going to be on the move, especially if you also carry a backpack, vest, gun ...etc like me. 2) the carrying strap is short and it is constantly sliding off of my shoulder. The strap is too short to go diagonal across my back, so I am fighting the d&^%$^&* thing most of the day. 3rd, is that if you wear a vest, once you are in the chair it is nearly impossible to get gear out of the lower pockets because they are trapped in beside the chair arms. I have eventually worked all those out besides the weight of the thing, but if you are not going to move around a lot and don't have to walk too far to your set up, I would reccomend it.
I also have the Ameristep version, and don't waste your money. Not nearly as comfortable, hard to get out of once your in it (without making a big racket), and the legs never seem to find level ground close up against a tree.
If I am am going to be on the move I have one of those web folding stools that I strapped a cushion to. I leave my pad on my vest up to provide cushion for my back.
I would think that someone would come up with a vest with a sturdy frame chair attached to it like a backpack, I think they would sell (I am sure I would add it to my 'collection')
