http://amzn.com/B0002XQJQ4It may not be quite as good as an Aeron, but I had an Aeron chair for two years at a former job, and this holds its own, especially for $129.  I've had it for something like 7 or 8 months, and both the chair and its comfort have held up well.  I can sit in this thing all day.  The cheap task chair it replaced, I would get tired of sitting in after 45 minutes.YMMV.

I would recommend trying it to a student.(I do not sell chairs, nor am I affiliated with Amazon.  I'm just a programmer who needs a comfortable chair.)
