Love this chair, easy to set it up. Can be done by a single person for most of the part, just putting the backrest may need some help. 
Neck support is something I never had in my earlier chair, but with height and angles adjustable - one can easily find the right position. Height of the chair and lumber tension can easily be adjusted. I have back pains and need lumber support, I still use my lumber pillow inspite chair having lumbar support.
