best seat I've found,,, super light to carry, and you can shoot 360 degrees while being dead silent,, only the seat post pivots so you just turn with your legs while sitting,,, when you are sitting on this it has 3 legs and two of them are yours you can turn completely around to shoot behind you just by walking your feet.
I leave mine together and just carry into the woods with it slung over my back with paracord.
you can adjust the height, your back doesn't need to be scraping against the tree, NO Tree trunk to hit your elbow and interfere with your draw, two positions to change back and fourth if your butt starts getting sick of one position you spin the seat 90 degrees for a different feel.
the back rest if needed is a tree but you lean forward to bring your body away from the tree and then you can silently turn or lean the seat while sitting on it to position for for a shot,,, you are not constricted on the seat itself because it moves with you its the best of both worlds. works perfect inside ground blinds where there are no trees, adjusts up or down to get a nice shot out those windows. set up in a grassy field shooting back towards the woods then just pull out of the ground throw it over your shoulder and head to the muddy marsh nothing stops this seat.
