Design comparison
Adjustable pillow vs contour pillow
Adjustable-fill pillows prioritize tunability. Fixed contour pillows prioritize a stable geometry.
| Feature | Adjustable fill | Fixed contour |
|---|---|---|
| Loft tuning | High | Low |
| Shape consistency | Variable | High |
| Ease for uncertain buyers | Often easier | More fit-sensitive |
| Reshaping | Usually possible | Limited |
Derila Ergo is a fixed contour. If you already know you like molded cervical shapes, that may be a benefit; if not, compare alternatives.
