i've tried just about every brand of quad fold chair on the market and yet to find one that is comfortable to sit in. i find these flat fold style chairs a million times more comfortable. seem to have much better support, esp lower back.

obviously comfort is a personal thing, so each to their own. also, if space is an issue, flat fold chairs can be a bit bulky.
