8. FAQ Section
Are ergonomic pillows worth it?
Ergonomic pillows can be a worthwhile investment for individuals with specific sleep posture needs. By maintaining neutral spinal alignment, they can improve overall sleep quality, though their value depends on selecting the correct size and shape for your body type.
