BobCo,

I have the same blind and I am about the same size as you. Cabelas makes this little folding stool. It has three legs and twists open. It fits nicely into the blind carrying bag right next to the blind itself. I believe it sells for right around $20. If I can find it on the website then I will post the link.

Edited:

Dang Padlock filtering system here at work won't let me on the Cabelas website because of the "weapons". Sorry.
