Adjustable-Fill Cooling Pillows: Custom Loft & Shredded-Core Airflow

By the CoolingPillows.com Editorial Team Criteria: 10-Point Pillow Spec Framework Sources: 18 Manufacturer-Verified Models

Adjustable-fill pillows use a zippered inner liner stuffed with loose cross-cut foam, microfiber, or Talalay latex ribbons. In addition to letting you customize height and firmness, loose fill creates interstitial air pockets that vent warm air when you shift positions.

Frequently Asked Questions

Do adjustable pillows come with extra fill in the box?

Yes, the Coop Cool+, Eden, Original, Cut-Out, and Adjustable Latex pillows all include an extra bag of fill so tall-shouldered side sleepers can increase loft beyond the factory fill level.

How do you store removed pillow fill?

Keep unused fill in a clean resealable bag in a dry closet so you can top up the pillow later if the fill settles over time.
