My wife and I have a couple chairs for our hunting blinds from cabelas too (Ameristep High-Back Chair on cabelas site) that "fart" every time you move. It's the fabric pulling tight and/or twisting around the frame bars. I slid the fabric over and put some duct tape under it, and doused it with baby powder that helped quite a bit. Graphite powder probably would have been a better choice, but baby powder seems to work.
My wife has a Cabelas 3D seclusion Gobbler Lounger (low seat with a back) that is fantastic. Comfortable, quiet, and pretty lightweight for as big as it is. It's a velcro strap to keep it closed, which I replaced with double D-ring strap to be quieter, but I REALLY like that seat/chair. I kind of expected it to "fart" too, like our other chairs, but it hasn't started yet. She uses it all the time when we're hanging out in the yard with guests.
