8. FAQ Section
Are ergonomic pillows worth it? For many, yes. If your current pillow leaves you with morning stiffness, an ergonomic pillow can provide the structural support that standard pillows lack. However, the value depends on whether you can tolerate a firmer, more restricted sleeping surface.

How long does it take to adjust to a new pillow? Most manufacturers and sleep experts suggest a transition period of 3 to 7 days. Your neck muscles and spine may need time to adjust to a corrected alignment if you have been using a non-supportive pillow for years.
