Noc doc: bad back, the exact reason I use strap on tree seats, my own Torges design and Huntmores. Now I know about weight of the Huntmore, and you need to be a little tactful, physically capable and mechanically savvy like my 59 year old wife to be able to carry one out, slap one together and adjust it in 3 minutes, so perhaps they are not for everyone. but once they are in place they are easy to get out of maneuver for a shot and sit relaxed in a ready to shoot position. If what you all are after is a nap why not just take out your favorite lawn chair. I have two that are real comfortable, however, my wife has to get the neighbors to come over and lift me out of one. I have found that the walk out to my favorite mile from the car spot to be a longer walk heading out compared to my Nifty seat, but a shorter walk heading back to the car compared to a long sit on the Nifty seat. Plus I missed a buck this year because I had to turn and lost my balance enough for me to miss with the Nifty seat so now I am mad at it and i don't care how easy it is to carry.
