With sciatica I have a problem with cushioned chairs. The mesh design offers just the right amount of support and comfort to avoid stirring up my nerve pain. Great chair for use at my home office desk.
The headrest is great. it is not hard to put together. It leans back to a resting position. It does not work quite so well when you are not leaning back but on the edge of the seat. I have only had this a few weeks and just use it a few hours a day but I like it much better than the other chairs for use on the computer. I do recommend this chair. It is not expensive either.
Overall I really enjoy this chair. The mesh is breathable the ergonomic controls have a decent range but I am 6'2" ~210lbs and it is just a bit small.The headrest hits the top of my shoulders at best and the base of the chair is a bit slim. If you're my size think twice otherwise its a great chair.
