The Neck Compression Index (NCi)
The Neck Compression Index rating (NCi) was developed by Osteopath and Chiropractor Andrew Macfarlane as a means of finding
a persons ideal pillow based on their own unique neck and shoulder measurements, weight, body shape and bed.
The NCi is the amount of pressure and weight you apply to your pillow. If your pillow can not support that pressure due to
its height and shape, it will force your neck and shoulder muscles to over-contract, causing you to toss and turn in
discomfort as they try to relieve the pressure. As a result, your sleeping pattern, so crucial to how you feel,
is disrupted.

The Neck Compression Index is calculated using the four factors mentioned above. For example if your NCi rating is 4/150
it means you need a pillow support of 4 for your weight with a shoulder width of 150mm.
With this information, we can create your perfect pillow tailored with just the right amount of neck support.
