Medium-loft pillows typically work best, keeping your neck aligned with your spine. Too high creates upward pressure on the disc; too flat offers insufficient support.

Both can work depending on your needs. Memory foam provides consistent support and maintains shape, while quality down offers adjustable loft and natural breathability for temperature regulation.

Back sleeping with proper neck support is often recommended. Side sleeping works if your pillow fills the space between shoulder and head without tilting your neck upward or downward.

Medium-firm support is typically ideal. The pillow should compress slightly under your head's weight while maintaining enough structure to keep your neck in neutral alignment throughout the night.

Yes. Pillows that force your neck into flexion or extension can increase pressure on the herniated disc and surrounding nerves, potentially worsening pain and inflammation.

Not necessarily special, but specific features help: adequate loft for your sleeping position, materials that maintain support, and construction that prevents your head from sinking too deeply.

Replace pillows every 1-2 years for optimal support. When managing herniated disc pain, worn pillows that have lost their supportive structure can compromise your neck alignment and recovery.
