Description
With an array of prestigious awards under its belt, the Simba Hybrid® Ultra Mattress is one of the most innovative mattresses money can buy. Known for its advanced sleep technology, Simba has crafted this highly supportive and intensely comfortable mattress with precision, delivering a truly exceptional night’s sleep.
The highest-ever spring count for tailored support
Featuring Simba’s highest spring count yet, this mattress includes up to 7,300 springs for outstanding personalised support. Titanium alloy Aerocoil® micro springs are positioned in the upper layers, compressing in response to your movements. Small yet highly responsive, these springs adapt to changes in weight distribution, delivering precise, tailored support without being felt.
Advanced spring system for enhanced comfort and pressure relief
Up to 2,500 high carbon steel Aerocoil® micro springs are layered deeper within the mattress to maximise support while encouraging airflow for a fresher sleep surface. At the base, the SupportCore™ system includes up to 1,000 barrel-shaped pocket springs, providing enhanced orthopaedic support and helping to maintain proper spinal alignment. A CertiPUR® foam base reinforces this structure for added durability and stability.
Innovative comfort layers for superior cushioning
At the centre of the mattress lies a stabilising core foam layer that maintains structural integrity and improves airflow. A unique PureLift™ layer, combining latex and coconut fibres, introduces elasticity and a gentle bounce for added comfort. Above this, two layers of Simbatex® foam contour to your body, offering personalised cushioning and effective pressure relief.
Natural fibres for breathability and cooling comfort
An innovative FusionCool™ layer blends wool, bamboo, charcoal, and kapok to create a breathable and comfortable sleep environment. These sustainably sourced fibres enhance airflow while providing plush cushioning. The soft, breathable cover incorporates Simba’s cool-touch Stratos® technology, delivering an instant cooling sensation. For added convenience, the cover is removable and machine washable, helping you maintain a clean and hygienic sleep surface.
