I'm a web developer and I sit about 6-8 hours on a normal day, and when I'm gaming or writing code for fun it can easily reach 18 hours uninterrupted (except restroom breaks).
Over the many years and different office chairs I've finally found the holy grail:
===> Serta Smart Layers Jennings Super Task Big and Tall
(NOTE: there seems to be another version without the word "Super" that I have also purchased and its bottom cushion/back support is sub-par. do be vigilant)
- Supportive, soft leather (or substitute I dunno) cushions
- Good neck/head support
- Comfortable arm rests (though after 6 years have begun to flatten)
