The Resti Zephyz Mattress is built for sleepers who want firm support, cooling comfort, and advanced temperature regulation. At its core, 1500 individually pocketed springs adapt to your shape, providing tailored support that minimises partner disturbance. A breathable gel comfort layer helps relieve pressure and disperse excess body heat, while the Cooler Extreme™ fabric delivers a fresh, cool sleep surface all night long.
❄️ Cooler Extreme™ Fabric – Scientifically Proven Cooling
Independently tested by leading European textile laboratories, Cooler Extreme™ fabric has been proven to:
- Pull heat away from your body faster (higher thermal conductivity)
- Prevent heat build-up (lower thermal resistance)
- Feel cool on first contact (low absorptivity)
- Increase breathability and airflow (thinner, high water vapour permeability)
This means you fall asleep faster, stay asleep longer, and wake up feeling fresher.
Features That Support You
- 1500 Pocket Springs: Each spring works independently for precise, responsive support.
- Gel Layer: Breathable and instantly adaptive, disperses heat and relieves pressure points.
