Vests and seats are different topics as far as I am concerned...
My hunting frequently involves a bit of moving around, and I have no desire to carry around a chair. Were I to hunt a smaller property, with little likelihood of movement, I would be in the lounger.
The cushion on the Tat'r is nice... Lean against a good tree, and I can fall asleep... But it is not as comfortable as the loungers...
I am a small guy, and have not appreciated the comfort of the kickstand vests I have tried. They seem cumbersome to me... I have friends who swear by them, and I have friends who swear at them... If you are looking into one of these, I would highly recommend trying before buying if possible.
