We got 2 of those chairs and requested assembly for extra charge. It was worth it. Great chairs and great service. Very happy with the product and how quickly they delivered it with onsite pick up.
It's hard to tell how the chair will hold up over time but it feels sturdy and is comfortable. We decided to use it without the neck support as I felt it pushed your head forward but it might be fine for someone of the correct height.
This will be a gift so it is still in the box but when I bought it I did check the store supply and there were several that had split and cracked fabric. When asked the clerk said those had been returned so I made sure to buy the warranty--bonded leather just doesn't hold up and I lost a $1300 sofa several years ago because I didn't know that.
