The mattress designed by sleep surface experts to provide pressure relief and a cooler night’s sleep

Exclusive to Harvey Norman, ThermoPure™ combines pressure-relieving Visco Elastic with PureCell™ heat dissipation technology to remove excess heat and humidity. New ThermoPure™ phase change material, our next generation comfort innovation, absorbs and releases heat to maintain a comfortable sleep surface temperature, for all season’s comfort.

The Technology Inside:

The most advanced temperature regulating comfort.

ThermoPure™ Gel beads absorb excess heat when you're too warm and release it when you're too cool, maintaining an even comfortable sleep surface temperature in all seasons.

Surface too warm

- heat is absorbed

Surface too cold

- excess heat is released

All night cooling comfort, you can feel instantly.

Adaptive Comfort

PureGel™ crystals conduct heat up to 4 times faster than regular mattress foams, for a cooler comfort. Balanced alongside ThermoPure™ phase change material, our mattress adapts to your body to create a more stable sleep temperature throughout the night.

Cool to the Touch

Our PureCool™ fabric feels instantly cool against your skin, helping to draw excess heat and moisture away the moment you lie down. Engineered to deliver up to 40% better cooling than standard fabric, it creates a fresher sleep surface from the first touch.

Adjustable Base Ready

ThermoPure™'s responsive all-foam design is engineered to work smoothly with MotionAdjust™ bases, so you can personalise your sleep position and maximise comfort.

Science-Backed Testing, Made in Ireland

ThermoPure™ comfort material is manufactured in Ireland at our purpose built facility in Dublin. Every mattress core is rigorously tested to ASTM™ and ISO standards, ensuring firmness, compression, density, and resilience meet the highest quality requirements.

We also work in line with European EN standards and align our testing protocols with guidance from NSAI, Ireland's official standards body. This comprehensive approach means you can trust ThermoPure™ to deliver a consistently supportive feel that's built to last.
