I've had a $100 "task chair" in my home office for a few years and it finally gave up the ghost. The chair had height adjustment and a lever that you pulled out to enable tilt back and pushed in to lock full upright. Well the chair was made with cheap enough materials that it was going to result in my death. In the past few months the back would tilt back over 30 degrees when LOCKED in full upright. Something was bending or breaking and I was going to get dumped tits over teakettle at some point. So last night I got a mid level office chair. Its rated as a real office chair designed for 8+ hours a day. The outgoing chair was like 2-4 hours. I don't know how official those figure are but its something Office Depot/Max lists for every chair they sell. Any way the new one has height, seat depth, armrest height, armrest rotate, armrest depth, tilt that locks in multiple positions, waterfall seat, and back height adjustment which also adjusts where the lumbar support built falls on your back. It was only $250 but its a MASSIVE improvement. Oh, and a minor, you don't know it until you have it feature... the castors are about 30% larger which makes it much smoother to move around.
