Fill affects comfort, look, and maintenance. Polyester (fiberfill) is affordable, holds shape fairly well, and is easy to care for. Down or down-blend fills feel soft and luxurious but may need regular fluffing. Memory foam or shredded foam offers firmer support and keeps shape for lumbar pillows.
- Fiberfill: good for budget and easy washing.
- Down/down-blend: plush, requires fluffing.
- Foam/shredded foam: supportive, good for back support.
Check care instructions on the product page and consider removable covers so you can keep pillows fresh with less fuss.
