Abrasion was the only reason I ever used a sack - and that was when I used an external frame pack, with the pad lashed to the outside.

Leaving the pad inside the chair kit (which, at age 60, I no longer consider a luxury) and rolling the chair kit around the stays serves the same anti-abrasion function as the stuff sack. I agree that the NeoAir seems like it needs more protection, but that may be wrong (when I laid it next to a Prolite, I'm not completely convinced that the nylon covering is any more or less fragile; a technical analysis might prove that it is.)

By the way, I used some silnylon (and flattering comments to my wife such as, "I owe you big-time") to modify the Compack chair into a full-length "lounger" type chair, so I didn't have to remove the NeoAir every time I wanted to sleep on it. It only added an ounce or two, and greatly improved convenience and function.
