The Hyken Mesh Task Chair is very comfortable and supportive but the headrest is useless because it does not touch the back of your head unless you slouch down into the chair.
I really wanted to like this chair but the seat ruins the whole experience. There is ZERO cushion on the sides so your legs will sit on hard plastic which causes soreness and pain within minutes! The seat is also way too cramped and doesn't offer enough leg room! The mesh on the bottom gives way to easily and it hurts my joints. A chair without a cushion on the sides is a terrible idea!
