Shopping for a new pillow can be confusing. Memory foam, polyester fiberfill, down, feathers — what's actually the difference? Here's a simple comparison to help you choose.
How each type feels
- Memory foam: slowly shapes to your head and neck, then returns to its form. It feels soft on top but stays supportive.
- Polyester fiberfill: soft and fluffy at first, but it tends to flatten and clump over time.
- Down and feathers: very soft and moldable; you may need to fluff it every night, and the height changes as the filling moves.
Support and shape
Because memory foam keeps its height, it can be molded into ergonomic shapes — like contoured or butterfly-shaped pillows — with zones at different heights for back and side sleeping. Regular fill pillows can't hold a specific shape for long.
Durability
Good-quality memory foam typically keeps its shape for years. Fiberfill pillows often need replacing much sooner because they go flat.
Temperature
Solid memory foam can feel warm. Look for designs with breathable mesh sides or ventilated covers to help air flow.
Care
You can usually machine-wash fiberfill pillows, but memory foam should never go in the washing machine. Instead, choose a pillow with a removable, washable cover. (See our guide: How to Wash and Care for a Memory Foam Pillow.)
Which should you choose?
| Memory foam | Regular fill | |
|---|---|---|
| Keeps its shape | Yes | Often flattens |
| Ergonomic contours | Possible | No |
| Machine washable | Cover only | Often yes |
| Feel | Supportive, slow-moving | Soft, fluffy |
