Frequently asked questions

How does the Casper Original Cooling Pillow keep you cool at night?

The Casper Original Cooling Pillow uses a layer of Phase Change Material (PCM) — a thermoregulating coating on the underside of the cover that absorbs body heat the moment your head touches it. Unlike traditional fabrics that warm up over time, PCM actively pulls heat away so you stay comfortable throughout the night.

What is Phase Change Material (PCM) in a pillow?

Phase Change Material (PCM) is a substance that absorbs and releases heat as it changes state — similar to how ice cools a drink as it melts. In the Casper Original Cooling Pillow, PCM is embedded in the cover to instantly draw heat away from your skin, creating a consistently cool surface without refrigeration or electricity.

Does the cooling effect on the Casper pillow wear off over time?

No. The cooling technology in the Casper Original Cooling Pillow is built into the TENCEL™ lyocell and cotton blend cover, which is inherently breathable and moisture-wicking. Unlike gel-infused pillows that can lose their effect, the combination of PCM and TENCEL™ is designed to maintain its cool-to-the-touch feel wash after wash.

Is the Casper Cooling Pillow good for hot sleepers?

Yes. The Casper Original Cooling Pillow is specifically designed for hot sleepers and anyone who runs warm at night. The PCM coating pulls heat away on contact, the breathable TENCEL™ lyocell cover promotes airflow, and the down-alternative fill resists heat retention — so you're not just cool when you fall asleep, you stay cool as you move through the night.

What firmness level is the Casper Original Cooling Pillow?

The Casper Original Cooling Pillow is rated Medium Soft with a Medium Profile, a balanced feel that works well for a wide range of sleepers. It's plush enough to cradle your head comfortably, but maintains enough loft to offer proper neck support throughout the night.

Is the Casper Original Cooling Pillow machine washable?

Yes. The Casper Original Cooling Pillow is fully machine washable. Wash on a gentle cycle with warm water and tumble dry on low. Regular washing also helps the pillow maintain its shape and freshness over time. For best results, wash every 3–6 months or as needed.

What makes the Casper Cooling Pillow different from other Casper pillows?

The Casper Original Cooling Pillow is our fan-favorite Original Pillow reimagined with cooling technology. It keeps the same beloved pillow-in-pillow design and down-alternative fill, and adds a PCM layer and TENCEL™ lyocell cover specifically for sleepers who want temperature regulation without sacrificing comfort or support.
