Customizable Plush Comfort

Our pillow is designed with a core of finely shredded memory foam that molds to the unique contours of your head and neck. It’s fully adjustable, allowing you to customize the pillow’s height and firmness to match your personal comfort preferences—ideal for side, back, or stomach sleepers.

Lasting Cooling Technology

Wrapped in innovative cooling fabric, our pillow provides an instant cool-to-the-touch sensation, boasting an impressive 0.4 Q-Max rating. Engineered to maintain its cooling effect throughout the night, this advanced fabric outperforms other pillows that tend to lose their chill over time.

Superior Shredded Memory Foam

At the core of our pillow is high-quality, freshly manufactured memory foam—not the scraps often used by other brands. This premium foam is meticulously cut into uniform pieces, ensuring a clean, durable fill that offers consistent support without any mess.

OekoTex Technology

OEKO-TEX® STANDARD 100 is a label for textiles tested for harmful substances. It sets the benchmark for textile safety, from yarn to finished product. Every item bearing the STANDARD 100 label is certified as having passed safety tests for the presence of harmful substances.

InstantCooling

With a high Qmax score of 0.4, our pillow's ultra cool-to-the-touch nylon top layer swiftly dissipates heat upon contact, providing immediate relief for hot sleepers and helping you drift off comfortably.

ContinuousCooling

Beneath the top layer, the innovative phase-change material regulates temperature and maintains cooling throughout the night. It absorbs and releases heat as needed, ensuring the instant relief lasts until morning.

AdjustableBoost

A premium blend of shredded memory foam and microfiber provides gentle, responsive support and is fully adjustable—you can add or remove fill to achieve your desired loft, perfectly aligning with your sleeping position.

    The best pillow I’ve ever laid my head on!

    This pillow is hands down the best pillow I’ve ever owned! I imagined it would be soft, but my goodness it’s more comfortable than I could have even imagined! So soft and cushiony and I love that you can adjust the stuffing on the inside to what you like. Get your best nights sleep and order one!
