great product!! The chair is more stable and glides easily on the carpet. It no longer drags on the bottom and is elevated a couple inches. I would highly recommend these casters for an Aeron chair!

I bought these for my new Aeron chair. The stock casters were too small and caused the center stem of the chair to bottom out on the carpet. I could have replaced them with 3 inch casters from the manufacturer but that would have cost $100 for a set of 5.... Click to review this product
