When on the ground I use the
Cabelas Turkey chair or Hunting Lounger and it is probably the most comfortable chair I have ever sat in. I even drink beer in the garage with it.
I sat in in once last year for 4.5 hours straight without moving before shooting one. I also carry my bibs and over boots on my back pack as you get cold just sitting still and not moving.
I just either back the chair up to the base of a tree, or find a broken limb and such to snuggle against. I tried winter turkey hunting in January and had 12 does and 3 bucks walk past me between 20 and 40 yards in 20 minutes. The last doe at 20 yards finally spotted me trying to video her with my phone.
