Aside from the chair itself it was not at all difficult to put together in fact I did it myself! If I had to make one change it would be to lower the back so that the neck rest would suit me better. I remedied my issue by adding a contoured pillow to the seat. I cannot say that my small issue was the fault of the chair I happen to be short and I'm used to making adjustments. Others have seen it thinks it's just as nice as I do.
I tried this chair several times at Staples and found it comfortable. But not comfortable at home. Even bought a "Purple Seat Cushion" from Bed Bath & Beyond to raise the seat in order for the arm rests to be lower. Arm rests are too high for me. Wish they turned outward or moved further down. I like the easy movability.
Needed a new chair for my home office setup. This one arrived on time fairly easy assembly. The instructions were good the packaging and color coding on the hardware provided was helpful. So far so good.
