this is the chair to get. Head rest lumbar support. What more do you need? You don't fatigue sitting in it all day. When you have a moment to breathe lean back and take a breather.
I took a risk buying this chair online without testing it at the store (no Staples stores in my city) and I'm pleased with the product. It's comfortable and breathable. I did find that the headrest is positioned farther forward than I would prefer so I decided not to use that part. Other than that I like it!
