I've purchased 5 of these now.  They're comfortable, come in a great range of colors, and stand up to normal wear and tear pretty well.  They don't stand up to a 13 year old boy using them for combat forts, but then again, what does?!  I come back to the same chair because it's a good value.

Pros: Easy to assemble, love the color variety, comfortable to sit it and maneuver.
Cons: Fabric seat seems to get dirty easily, but that might just be my 13 year-old wildman!
