The headrest rest was exactly what I needed for this chair. Im a very tall, heavy set man and now my head and back have the support I need. I was impressed with how 'original equipment' the piece looks as well. if you dont know about the replacement rollerblade styke wheel casters, you might want to check those out too.

I've been seeing these rollerblade-type wheels all over but I didn't wanted to take a chance on the sizing for my Aeron chair. This set is perfect. Removal was extremely easy as well. My chair now easily glides- no more grind, quiet and seems better for the hardwood floors- I threw out the hardwood floor mat. I love these wheels and ordering 2 more sets for my kids' computer chairs which seem to also be compatible. There's envy in my household with these wheels!
