How often should you replace a pillow?

A fixed replacement calendar is less useful than checking condition, hygiene and whether the pillow still provides the fit you bought it for.

Replacement signs

• The pillow no longer returns to shape.
• Fill has shifted or clumped permanently.
• The cover or foam has deteriorated.
• Cleaning no longer keeps it acceptably fresh.
• Your needs or sleeping position have changed.

For molded foam, follow the manufacturer's care instructions and avoid washing the foam unless the product label explicitly allows it.
