Overall the chair is very good. Comfortable adjustable to my needs. However the courier service that Staples uses might be the worst I've ever seen. They couldn't find the address then 3 days after it was supposed to be delivered they realized they couldn't deliver packages to PO boxes. So I end up changing the delivery address and waiting for shipping again. When I finally get it I'm roughly 3/4 of the way assembled when I take out a part that had broken during delivery. So not only was the courier roughly a week late the chair came broken. I ended up exchanging it in a store and will probably never order Staples delivery again.
One of better office chair to use for long hours of working. I typically sit around 8-10hrs a day and i wont feel exhausted. Head support/Lumbar support is good !!
