I can not recommend this chair. I am on my 3rd set of casters, and finally figured out what the problem is. The holes for the casters to sit in are not set in the same orientation on each of the legs. Meaning that one caster might be leaning out several degrees and an opposite caster might be leaning in several degrees. I can not simply pull the chair in any one direction without weight on the chair, because of this. I am outside of my return window, not to mention the size / cost of returning an item such as this. I definitely can not recommend this product.
Horrible Chair
