    Wrapped in IceClass™ fabric, the surface feels instantly cool, helping to regulate temperature like high-performance sportswear. This reduces overheating and night sweats, supporting hydration and optimal brain function for a more restorative night’s sleep. Added Halofoam® cushioning enhances flexibility, while the Pro-Bio® cover treatmentprovides natural defence against allergens, bacteria, and odours. A breathable polyester layer, made with at least 70% recycled materials, ensures both sustainability and freshness. Finally, encapsulated edge support reinforces the mattress perimeter, maximising space and durability.
    The Altitude Aura Luxe isn’t just a mattress — it’s Mammoth’s ultimate expression of luxury, science, and wellness, giving you the restorative sleep your body and mind truly deserve.
