xCool, customizable comfort with UYWO Cooling Pillows
Meet the king size set of two memory foam pillows designed for hot nights and versatile sleep styles. Each pillow blends a plush, breathable surface with an adaptive core, letting you tailor loft and firmness while you drift toward sleep. The result is a balanced, supported feel that remains comfortable through shifting room temperatures and preferred sleep positions.
Allergen-aware protection you can feel
The inner pillowcases use OEKO-TEX certified fabric and a 3D airflow mesh with 0.1 mm pores. This nano-barrier design helps reduce exposure to common sneeze triggers like pet dander and pollen, without sacrificing softness or comfort.
- Soft, skin-friendly fabric that’s gentle on sensitive skin
- Mesh airflow supports continuous breathability
Climate-adaptive sleep tech
The dual-temp outer pillowcases feature a PCM-infused design. The cool side uses a 64.4°F gel fiber, while the warm side is built with 89.6°F bamboo rayon-infused fabric. Lab tests show the cooling side delivering a noticeable drop in surface temperature (around 37.4°F cooler) and the warm side providing gentle warmth (about 36.5°F warmer).
Whether you’re a hot sleeper or simply want flexible comfort, this setup responds to body heat and room conditions to help you settle in more quickly and stay comfortable as the night evolves.
Zero-pressure support with lasting loft
The pillow core blends NASA-inspired viscoelastic foam with non-Newtonian gel particles to disperse pressure more evenly. The material retains impressive rebound—about 92% after extensive use—while maintaining comfortable neck alignment across different sleep positions.
Personalized loft control
A patented metal dual-zipper system and neodymium magnetic seals enable precise height adjustments. A removable fill-port makes it easy to add or remove foam for the exact firmness you want, whether you sleep on the side, back, or stomach.
Ergonomic, breathable design
Engineered to cradle the neck with airflow to the surface, the pillows promote a cool night’s rest while providing targeted support for stiffness and tension points. The design focuses on comfort and function without promising results for specific conditions.
Care and quick-start tips
For optimal performance, air out the pillow for 24–48 hours after unboxing to dissipate any neutral packaging odor and allow the advanced materials to fully expand and settle.
- Loft adjustability supports multiple sleeping styles
