FAQ Section
Are ergonomic pillows worth it?

How long does it take to adjust to a new pillow?
Most users require an adjustment period of 3 to 10 days when switching to a cervical support pillow. During this time, the muscles in the neck and shoulders are adapting to a new postural alignment, which may cause temporary awareness of the pillow’s firmness.
