Want to know how to make a super comfortable seat for cheap?
I had an innertube style turkey seat, but it kept going flat so I decided I would get a new innertube to go in the one I had. Unfortunately, or fortunately, the innertube I ordered from Cabela's (unfortunately, they don't sell them anymore) was a couple inches bigger, so it didn't fit. I then decided I would make my own. Here is how you do it. For about $5 you can't beat it.
First order the innertube. Mine is 15" accross uninflated. The # on it said 4008.

Then cut out two 20%22 circles of camo (or drab) fabric. The tougher the better I guess. Have the camo sides facing together.

The sew the two pieces together having the stitches about an inch from the edge. Sew all the way around except leaving a 8-10%22 gap (so you can put the innertube inside it).
Then turn the pouch for the innertube back out so the camo is showing while hiding the terrible stitch work (in my case). Slide the uninflated innertube in the pouch and inflate it with a bike pump or what ever pump you have.
You now have a very comfortable seat for turkey or predator hunting. To make it easy to carry around, put a sting thru the top and bottom of the open slot of fabric and attatch a clip to clip to your belt.
