Thermocool™ Side Sleeper Pillow

The Coolest Pillows for the Hottest Women

"It is actually cold when you squeeze it. I don't understand how but I can feel it pulling the heat out"

Proudly Made in Australia
100% Australian Owned & Operated

For that fresh ‘cold side of the pillow’ feeling, all night long.

Are you hot in bed? Us too. Are you a side-sleeper? Us too. That’s why we made the Phenxx Thermocool™ Pillow Side Sleeper, a pillow designed to treat the hot flushes, night sweats, and discomfort of hormonal changes – and to do it in luxurious style.

Say goodnight to restlessness and hot nights, and wake up refreshed ready for your day!

Our Thermocool™ Pillow uses Reactex® technology to draw out excess heat and soothe you with coolness all through the night. It takes just 8 seconds of natural pressure to initiate the cooling feeling, and naturally “recharges” itself through the day, ready to welcome you back to restful sleep whenever you need it.

The Phenxx Thermocool™ Pillow is made perfectly for side sleepers like us: firm enough to contour your neck and shoulders, and just high enough to support your spine without being too high. You haven’t slept until you’ve had a Thermocool™ sleep.


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 remains cool, 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.

Designed for Side Sleepers

This pillow is specifically designed to cater to those of us who sleep on our sides. At 14cm high, it

offers support for your neck, shoulders, and spine, with raising you up too high. It is, for lack of a

better word, perfection.
