Advanced Support Technology
The Mammoth HealthPRO® Advance Mattress combines innovative sleep technology, clinically informed design, and expert British craftsmanship to deliver exceptional comfort and support.
It features an advanced 3600 dual-layer pocket spring system, combining 2,000 mini pocket springs with 1,600 full-height pocket springs. Each spring responds independently to your body’s movements, providing highly adaptive support and helping to maintain optimal spinal alignment throughout the night.
This sophisticated spring configuration delivers a stable yet responsive feel, supporting every sleeping position while helping to minimise motion transfer for a more peaceful and undisturbed sleep experience.
Medical Grade™ Comfort and Pressure Relief
At the core of the mattress is a generous 60mm layer of Medical Grade™ Foam, designed to deliver exceptional pressure relief and targeted body support. The foam incorporates three distinct comfort zones, providing tailored support exactly where it is needed most and encouraging healthy spinal alignment to help reduce pressure on joints and muscles.
Integrated within the foam is Mammoth’s innovative PostureCell® Technology. Specially engineered cells move independently to contour naturally to your body shape, promoting even weight distribution, enhanced comfort, and improved circulation. This intelligent design also helps reduce partner disturbance, making it ideal for shared sleep environments.
The open channels between each PostureCell® encourage continuous airflow, helping to disperse excess heat, moisture, and allergens while maintaining a cooler, fresher, and more hygienic sleep surface.
Enhanced Comfort and Edge-to-Edge Support
To maximise durability and sleeping space, the mattress features Mammoth’s advanced EdgeMax™ System. High-density foam reinforcement around the perimeter helps prevent roll-off, improves stability, and provides consistent support right to the edge of the mattress.
The sleep surface is finished with exclusive WAVE™ Performance Fabric, enhanced with innovative WAVE™ carbon particle technology. This advanced material helps create a fresher, cleaner, and more balanced sleeping environment while enhancing overall comfort.
Completing the comfort experience is a luxurious deep-quilted mattress top, adding a layer of plush cushioning and softness while maintaining the mattress’s underlying firm support.
Practical Design and Health Benefits
The HealthPRO® Advance is crafted using hypoallergenic materials that naturally resist common allergens and dust mites, helping to create a healthier sleeping environment.
Designed for convenience, this easy-care no-turn mattress only requires regular rotation to maintain its performance. Traditional flag-stitched handles make positioning and rotating the mattress simple and straightforward.
With a substantial 30.5cm depth and a firm comfort rating, the mattress is ideal for sleepers seeking enhanced support and a more structured sleeping surface.
