Titanium alloy Aerocoil® springs
Two layers of conical micro springs for personalised support; each features up to 2,000 titanium alloy springs, arranged into 13 ergonomic zones to mirror areas such as hips or shoulders.
CertiPUR® stability layer
Breathable, open-cell foam layer provides optimum structural layer between the Aerocoil® spring layers.
Ultra layer of Aerocoil®springs
Exclusive to the Ultra mattress, up to 3,500 high carbon steel Aerocoil® springs packed together in an innovative single layer to maximise support and airflow.
SupportCore™ base & protective casing
Up to 1,000-barrel springs provide firm support to the edge of the mattress, preventing dipping at the sides. Spun bond fabric casing provides springs with extra protection and longevity.
What’s so different about the Hybrid® Ultra?
Our tech team left no stone unturned. Until they found what they needed to create their perfect mattress.
Our technologists insisted on a whopping 8,500 in the Ultra, more than any other Simba mattress. It’s the only way to get perfection they said, and we could hardly argue with that. So there are 7,500 titanium alloy Aerocoil® micro springs in the main part of the mattress: 4,000 of them nestle centrally in 13 support zones to cradle your unique body contours, and another 3,500 of their high carbon steel cousins sit further down the mattress for maximum support and airflow. And standing sturdily at the base is our SupportCore™ spring unit, with yet another 1,000 pocketed, tempered steel barrel springs, providing edge-to-edge support with absolutely no dipping at the sides.
We know being too hot stops us sleeping well. That’s why our perfection-seeking tech team created the cooling, cushioning Simbatex® foam in the first place. So what is Simbatex®? It’s a less dense, open-structure foam, offering much better cushioning and airflow; it’s also infused with graphite, to help heat and humidity flow away from the body. No surprise then, that the marvellous Ultra is the ONLY Simba mattress to have a revolutionary, double layer of this miracle stuff. Because obviously the more there is, the cooler and more comfortable the mattress will be.
Our chief technologist and his team were laser-focussed on creating the coolest but comfiest top layer for the Ultra. A combination of breathable wool and airy bamboo was the best performer in lab tests, even more so after the team added a boost of cooling charcoal. But there was something missing, something that would turn excellent into exceptional. And then the team discovered Kapok. Kapok has been overlooked and overshadowed for decades, until now. Found in the fruit of the kapok tree in the rainforests of Southeast Asia, it’s naturally silky soft; with an air content of 80% it’s one of the lightest plant fibres on earth, and has a fine wax coating that makes it moisture resistant. This high air content makes it breathable, thermo- regulating. Magic ingredient located. And so after all that, no chemicals, no treatments, no technology. Just a fusion of natural materials at their wondrous best.
When they couldn’t source the perfect, pressure-relieving support layer they wanted, our heroic tech team realised they’d have to invent it themselves. But being innovative 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, believe or not, coconut. Yes, coconut. PureLift™ is the very successful fusion of latex, well known for its amazing natural elasticity, and coconut fibres, which as we now know, are famous for their properties of resistance, bounce and durability. In product testing, this unique blend created an incredible spring-like layer with superb pressure distribution, adapting beautifully to your body shape for exceptional and complete support. And by the way, it also scored top marks for breathability and airflow… So it’ll keep you as cool as a coconut.
