Bought this for a home office and it's everything I'd hoped for. Good lumbar support, the seat is deep enough, and the waterfall slope at the front of the seat is very comfortable. Foot rest ring is stable. I love the feature where the arm rests can swing up and back, out of the way. It helps me move closer to the desk, or frees me up for unencumbered keyboard work. Or, bring that back down when I'm stuck on a call and want to relax a bit.  I bought the blue which I'm very happy about. It's just the right spark in my home office and looks just like it's pictured. 
I've seen what happens to chairs like this in workplaces where they're used all day every day.  I'm 128 lbs. and in the chair just a few hours a day, so I"m not going to be putting much wear and tear on it. I see the chair description says its weight limit is 250 and I'd believe it. 
Hubby put it together for me--said the only tricky part was the arms. Other than that went together easily.
