Never tried the IKA Markus, but I've had quite a few office chairs quickly go downhill at the 2-3 year mark. I'm pretty big at 6'6" / 275lbs, and I am legitimately in my chair for 50+ hours per week, so that may have something to do with it. But this is the first chair I've owned that, after 3 years of constant use, is still in excellent condition.
