Nice chair.... Went together without much of a problem. However when I got to the last piece the Head Rest it was broken. I called the store and the manager was very helpful...he took a headrest from another box and it was available to me for pickup later that day for a clean swap.
I have severe lower-back problems including nerve damage compressed discs sciatica and so on. The Hyken Chair is the ONLY chair I have found where I can sit at the computer for an hour and get up without any increased pain. Not only is it comfortable it also makes it easier to sit up straight and contract my abdominal muscles which takes pressure off my back. I have three chairs: 1 at my home computer 1 at my home sewing machine and 1 at my office desk/computer. What a pleasure to have found a chair that is comfortable and does not put added pressure on my lower back. These chairs are worth every penny of the cost when pain reduction is a factor. 5 Stars with no reservations.
