Firstly lets start with the contoured shape of the neck support (at times also known as a neck-roll). The neck support mechanism supports the upper spinal cervical curve of the neck and the head and this in itself helps prevent headaches and neck strain after prolonged sitting for many hours at a go.
Please note that usually, headaches and neck strain can result from a lack of neck support.
If your work or your child requires long hours to sit on a chair to do homework, draw art or to study, then do consider getting the IChair Junior or one of our Ergonomic Mesh Chairs as daily seated tasks allow for a reclined posture (e.g. teleconferencing, interviewing, a power-nap or just a moment to relax) an ergonomically correct headrest can deliver a high level of comfort.
