Pretty innovative. This hyper-portable foldable chair is an awesome addition to any normal sized human's outdoor sitting repertoire. Us giant folk will probably have to wait for the TreoXL to drop. The Treo Chair is contained inside of a 4.5 x 11" tube that also double as the chair's legs when unfolded. Check the quick five second animation for a little more insight on how it works.
I have to admit it would have been a lot cooler if it just kind of popped out of tube when unfolded(kind of like the way the run-of-the-mill outdoor foldables do), but it's not like it's a ton of steps in having to put it together. The Treo comes in several colors and handles 250lbs.
