Serta Smart Layers Jennings Super Task Big and Tall Chair BlackSlate by Office Depot & OfficeMax In got this one about 9 months back it's great.....It's wide enough and the arms raise and lower depending how I rest my elbows on the chair. Good for mouse use and adjustable tables. It's durable had a very long warranty like 10 years springs inside the seat so it doesn't' flatten. I can clean it with Carpet cleaner and it will be fresh and clean. The only thing I don't like about it I wish It would raise a 2-3 inches higher it raises but then I just lower my table. You want to relax in a chair and keep your spine in shape get this chair.
