8. FAQ Section
Are ergonomic pillows worth it?
Whether an ergonomic pillow is worth the investment depends on your specific sleep needs. For those who consistently wake up with neck tension, a structured pillow can provide the necessary support that standard pillows lack, though they often require a higher upfront cost.
