I definitely like this idea: Design your own Herman Miller Aeron in 3 minutes — You can customize the tilt, arms, arm upholstery, size, back support, base and frame finish, casters, and fabric. The fact that you can customize so many aspects of the chair to make your computering more comfortable is the most appealing part of this exclusive offer. I don’t know about you, but I spend 12-14 hours in a desk chair. Do you think that’s too much time? :)
