I've tryed just about every seat out there except the strap on the side of a tree type seat. Can't always find a tree in the brush I hunt in. Have not found the perfect seat most likely does not exist, all have there pros and cons. I use to use the Niff-T-Seat its small, light weight, quiet, can move/rotate quietly, some adjustablity. Can't sit it in for more than an hour or two then the legs start getting the shakes and I'm usually out hunting longer than that. The bucket seat is cheap somewhat quiet and you can get the rotating seats for it, a bit cumbersome in the brush and noisy if your not careful, can be unseady if the ground is uneven. The Double Bull seat the one I'm using this year, it is quiet easy to carry set up comfortable, can be a bit off balance on uneven ground, reasonabley ok to rotate some but not as good as the rotateing or niff t seat. All Terrain Seat expensive, the new ones seem to come with a pad a must on the hard plastic, rotates very well, adjustable legs nice, noisy to carry and set up. I'd use it more and used it all last year but I'm concerned with the noise factor. If I ever get around to making a polarfleece bag for it I'll start using it again.
The prefect seat would be very quiet to carry and set up, have adjustable legs, have a back rest, be able to rotate 360 degrees with no noise, hold 500lbs, be very comfortable on the butt and back, less than 5 lbs, $50 or less, something you could sit in all day and have no pain.
yea I'd better get my product line moving so I can make some money on this one....
