How long does it take to adjust to a new pillow?
Most people require an adjustment period of 3 to 14 nights when switching to a new pillow. During this time, the body adapts to the new alignment and the materials begin to “break in.”
Are there downsides to cervical pillows?

How often should you replace a pillow?
Generally, pillows should be replaced every 1 to 2 years. Memory foam pillows like the Polysleep Pillow often last longer (up to 3 years) due to the higher density of the materials, but they should still be replaced if they lose their shape or ability to support.
