Simba Hybrid® Ultra Mattress
Our dream mattress. A luxurious cocooning fusion. Thirteen layers of remarkable natural materials and our signature tech.

Hybrid® Ultra: Tech Spotlight

1. Naturally Cool. Naturally Dry.

Our tech team were laser-focussed on creating the coolest, most comfortable top layer for the Ultra. In lab tests, a combination of breathable wool, airy bamboo and cooling charcoal was the best performer. But there was something missing.

Meet natural, silky-soft kapok. Found in the rainforests of Southeast Asia, kapok is one of the lightest plant fibres on earth, with an air content of 80% and a fine wax coating that makes it moisture resistant. The high air content makes it breathable, thermo-regulating.

2. Simbatex® foam technology

We know being too hot stops us sleeping well. That’s why our tech team created cooling, cushioning Simbatex® foam in the first place. But the Ultra is the only Simba mattress to have a revolutionary, double layer of it.

Simbatex is an open-cell foam, with a less dense structure that offers much better, springier elasticity and more airflow; it’s also infused with graphite, a natural heat conductor which helps excess warmth and humidity flow away from the body.

3. Purelift™ Ergonomic Support

Being inventive isn’t always about creating new materials; sometimes it’s about finding fresh ways to use traditional ones. Which is exactly what our tech team did with latex and, coconut.

PureLift™ is the fusion of naturally elastic latex and breathable coconut fibres, famous for their properties of resistance and bounce. In product testing, this unique blend created an incredible spring-like layer with superb airflow and pressure distribution, adapting to your body shape to provide exceptional and complete support.

4. Best Aerocoil® spring comfort

Our technologists insisted on 8,500 springs in the Ultra, more than any other Simba mattress. They said it was the path to perfection, and we couldn’t argue with that.

4,000 titanium alloy Aerocoil® micro springs sit in the upper layers. You can’t feel them, but they compress individually in response to your body, providing ergonomic pressure relief and limiting transfer of movement.

3,500 high carbon steel Aerocoil® micro springs sit further down the mattress to maximise support, gently pushing fresh air through the mattress as they compress.

The Hybrid® Ultra also features our SupportCore™ base, with 1,000 pocketed barrel springs to ensure 100% edge-to-edge support.
