Mojostick,
You say you sat on a 360 chair, but thought it was too "Big & Heavy" for your taste. Hmmm...
A 720 Stool is "Larger in Dia." when folded up and basically the same "Weight" as a 360º Chair, especially, "if" you can find a backrest for it!
The 360º is the size of an Office Chair when set up, and has a full size backrest and adjustable lumbar for all day comfort. The 720 Stool has a flat bench seat, and a small backrest if you can find one. Which is about half the size of a 360º Chair.
So you are basically saying, you personally like a chair with a less comfortable seat pad and smaller backrest? That is also harder to carry and pack in?
Don't you find it Funny how everyone wants to compare their stool to a HuntMore 360 Chair!
Should have bought a HuntMore!
