They're terrible chairs. A mesh back is nice but you need a proper seat. The Aeron cuts off circulation to the legs. It's also about 5x overpriced. I just upgraded to a low end model from a no-name brand. [1] It's honestly a better chair.
Well it is the product of a world class design firm. Even if it was a mistake to have a mesh seat they got most everything else right. But it's telling that the Herman Miller Embody (successor to Aeron) has a real seat.
I didn't mean to sound contradictory. I actually sold mine on Craigslist! But a spike in Aeron chair sales may not imply that a bubble is popping. It might just be that startups got off the bandwagon and decided to care about their sorry butts. Literally.
Sounds like you might have gotten the wrong size. I used to do 12-13 hours sat in one of those at the office, with only a short break during the day to grab a snack, and never had any problems.
