For restless or fidgety sleepers seeking relief from hot flushes or night sweats, your chariot has arrived. Our Phenxx Thermocool™ Adjustable Cooling pillow is your silver bullet if you’re struggling to find comfort at night, tossing and turning, trying to alleviate the unpleasant symptoms of hormonal changes.

We’ve been there, and we’re right there with you.

This advanced cooling pillow is designed to be modular, allowing you to add or remove the internal foam cubes to change the height, weight, and even the firmness to suit you perfectly. Its natural construction is non-toxic and hypoallergenic too, so you can bend it and fold it and twist as much as you want and still wake up feeling refreshed and restored.

Reactex® technology is what powers the Thermocool™ adjustable pillow, soothe you with coolness all through the night. It takes just 8 seconds of natural pressure to start cooling, and naturally “recharges” itself through the day, ready to calm you back to restful sleep whenever you need it.


The Reactex® technology functions like an efficient central air system for your sleep. Comprising

three layers of advanced cooling technology, each layer amplifies the cooling effect, drawing heat

away from your body and securely storing it within the pillow. This innovative design ensures the

pillow not only remains cool but draws excess heat out of the sleeper, providing continuous relief throughout the night.

Ultra Hygiene

At Phenxx, we have almost spiritual respect for our bodies. So we use only non-toxic, hypoallergenic

and OEKO-TEX Standard 100 certified materials. That keeps you comfortable, safe, and feeling fresh

‘til daylight.
