Is the Herman Miller Aeron Chair Size C Good?
Yes. I think it is an excellent chair if you need more seat depth and width. During my testing, I noticed I could change my sitting position more often without feeling cramped. The larger frame also made long meetings feel easier because my body had more space to relax. The mesh stayed cool all day, and the chair still felt stable when I leaned back.
