A premium balance — cushioning yet supportive. Vitality Pure keeps you cool, aligned, and pressure-free, delivering a refreshing sleep surface designed for recovery and rejuvenation.

The Vitality Pure mattress from Mammoth’s Comfort Collection is crafted for those who demand more from their sleep. At its heart lies 70mm of Medical Grade™ Foam, scientifically proven to outperform memory foam in pressure relief, cooling, and responsiveness. Combined with Halofoam®, it provides targeted cushioning and flexibility so you move freely without losing support.
Wrapped in IceClass™ fabric, this mattress feels instantly cool to the touch — just like high-performance sportswear. The fabric regulates temperature, helping you stay cooler in summer and warmer in winter. By reducing night sweats, it also supports better hydration, which is essential for healthy brain function and deep, restorative rest.
The 5-Zone PostureCell® Technology adapts to every curve of your body, offering softer support at the shoulders and hips, with firmer reinforcement through the lumbar zone. Encapsulated edges keep the mattress strong from side to side, giving you more sleeping space and reducing roll-off. Finally, the Pro-Bio® cover treatment offers a natural, chemical-free barrier against allergens, bacteria, and odours — creating a cleaner, fresher, and healthier sleep environment.
Investing in a Mammoth isn’t just about sleep — it’s about giving your body and mind the tools to recover, restore, and perform at their best every day.
