Most users require 7 to 14 days to adjust to a cervical support pillow. During this time, the muscles in the neck and upper back may feel slightly sore as they adapt to a new resting position.
Are there downsides to cervical pillows?
The main downsides include a lack of versatility for multi-position sleepers (like stomach sleepers) and a potentially long adjustment period. Additionally, their unique shapes may not fit standard decorative pillowcases.
How often should you replace a pillow?
Most experts recommend replacing polyester fiber pillows every 1 to 2 years. Signs that a replacement is needed include visible yellowing, permanent lumps, or a loss of support that leads to morning discomfort.
