I am very happy with my Kelburne desk chair. I would also like to bring to your attention that the employee that helped me that day went way above and beyond to help me in every way. His name was Christian Diaz.
This chair is very firm (what I needed) level with my desk and other than putting in one of the wheels (it pinch my finger) & lining up the last 4 screws (ALWAYS a Issues With these Chair) went together easy enough. The nice thing was the sale price free shipping & the extra $25.00 off I got by ordering it online. The price was less than half the cost.
