Only a few days of experience with my new bungee office chair. Before this I had a Herman Miller Aeron office chair that I bought used after the dot com bust in 2000 and it finally wore out after many additional years of use. So far I'm finding that the bungee chair is very comfortable for me. Particularly at the front edge of the seat where some chairs can be uncomfortable on my legs. The bungee chair looks very well built and I hope to get many years of use out of it. Only time will tell, but so far it is a winner!
