Over the years, I've used many items.
Foam seats, folding "stadium seats", ect. when I could still get down on the ground, & back up again with ease.
Since herniating a pair of discs though & getting older, it has become a lot less easy to do.
Now my seat of choice is the one pictured below.
I don't even know what company made it. (I bought it @ a garage sale for $1.LOL
I've little doubt that some company out there still makes a version of it.
It actually is designed for a fisherman.
Inside was a foam "cooler" area, I'm assuming for worms & such, which I removed. There also is a "tray" inside.
It holds my facemask, gloves, drag, some extra ammo, compact binocs, & a lanyard of calls (which keeps them from "banging" together while walking).
There's a carry handle in the top of the hinged lid.
And, I'm not a "light-weight" fella, {but I'm workin' on it}, and it holds me just fine.
Granted it isn't a Lazy-Boy, but it's not overly uncomfortable.
It allows me to sit about 16" off the ground, to see over the tall grasses we sometimes have here in Kansas.
And, it allows me to pivot my shooting position when necessary.
I keep threatening to add a foam/upholstered top to it, as well as some camo paint, but I never have.
