Plush yet supportive — layers of springs combine with advanced foams and cooling fabrics to create a mattress that feels weightless, cushioned, and pressure-free.

The Altitude Aura represents the pinnacle of Mammoth’s Comfort Collection — a luxurious hybrid that blends 2000 deep-core pocket springs with 2800 mini springs for unrivalled comfort and responsiveness.
At its foundation, the 2000 core springs provide stable, long-lasting support, while the 2800 mini springs sit closer to the surface, adapting to every contour of your body and enhancing breathability. Above, 60mm of Medical Grade™ Foamworks with 5-Zone PostureCell® Technology to relieve pressure and maintain correct spinal alignment.
Wrapped in IceClass™ fabric, the surface feels instantly cool to the touch — just like high-performance sportswear. This temperature-balancing material helps reduce overheating and night sweats, keeping your body hydrated and your brain functioning at its best.
Halofoam® adds a layer of elastic, pressure-relieving comfort, while the Pro-Bio® cover treatment offers natural protection against allergens, bacteria, and odours. The breathable polyester layer, made with at least 70% recycled materials, adds to the eco-friendly design. Encapsulated edges reinforce the mattress perimeter, maximising sleeping space and long-term durability.
Altitude Aura is more than a luxury mattress — it’s a science-backed investment in your sleep, health, and long-term wellbeing.
