I like one with a little cushion for my boney butt. But not too much! And big fluffy recliners make my lower back hurt. Couches just promote poor posture. I really like my office chair. It's got lumbar support and everything. One bad thing about it is that I put one of those rollerblade wheel kits on it and now it rolls too easy! Just resting my palms on my keyboard will make my chair start rolling back! So I have to lock the wheels... Which just adds an unnecessary layer of complexity... the rollerblade mod SEEMS like a fun idea, until you're in it-would not recommend!
What say you?
