Why Simba feels so comfortable for everyone

The tech inside the world’s most five-star reviewed mattress brand.

All Simba Hybrid® mattresses combine unrivalled comfort layers at the top and tailored support layers at the base.

The upper layers feature thousands of our tiny, titanium Aerocoil® springs; these patented, pocketed springs flex and compress individually to absorb impact as you move and in response to pressure, giving a hugged, floating sensation to most sizes or sleeping styles. The base layers feature zoned support to help keep the body correctly aligned, with gentler support and extra cushioning for the shoulders and lower back.

There are many ‘soft to firm’ rating systems in the mattress industry worldwide. As a guide, our mattresses provide medium-firm support on one scale. Independent studies have suggested medium-firm mattresses, on some rating scales, promote sleep quality and comfort.

5ingenious things you should know about the Simba Hybrid® Luxe

It’s simple really: we’d love to help you sleep soundly and comfortably, so we use all the latest engineering and technology to do so. So have a read about all our unique and patented innovations; at the very least, your new scientific knowledge will impress your friends…

Three layers of titanium
Aerocoil® springs

Maximum comfort, minimum size

Our patented Aerocoil® springs are key to our award-winning mattresses. They’re made from super-strong titanium, so even in a micro size (they’re just 2.5cm high, with wire the width of a very thin paperclip) they provide the comfort you need. And being so small and fine, you won’t be able to feel them. Not even when we position them at the top of your mattress. Which is important, because that’s exactly where your body needs them.

Each spring compresses inwards whenever pressure is applied, which prevents the transfer of motion (however much your partner tosses and turns). And as the springs compress, they gently push air through the mattress, providing cooling, extra airflow.

There are an opulent three layers of them in the Hybrid Luxe, for the best possible cushioned comfort; we’ve stacked a double layer (up to 4,000) near the top, ready to react to your every move, with another layer in the middle (up to 1,000) to ensure maximum support. And we’ve fine-tuned each one to create thirteen zones of differing resistance levels, to perfectly support the parts of your body that need more cushioning such as hips and shoulders.

Simbatex Foam Technology

Traditional memory foam

The fresh feel of
Simbatex® foam

For pitch perfect temperature control

Being too hot at night is a big no-no for sleep. That’s why our sleep scientists created our innovative Simbatex® foam; it’s an open-cell foam, which offers more elasticity and 30x more airflow than standard memory foam. We’ve also infused it with natural, heat conductive graphite, to draw away excess warmth from your body.

So when it comes to comfort and temperature regulation, it’s absolutely clear that our patented Simbatex® foam is a high-tech winner. That said, we know that LESS foam is definitely more when it comes to protecting the planet. Consequently we’ve chosen to replace our foam base with our new SupportCore™ sprung base, resulting in up to 61% reduction of foam in our Hybrid mattresses.

And you thought foam was just, well, foam? Not in our book.

  • Breathable, anti-allergy covers
  • Antibacterial, bamboo-infused wool layer
  • Open cell Graphite Infused Simbatex
  • Two layers of titanium Aerocoil® springs across 13 zones
  • CertiPUR® stability layer
  • Aerocoil® Spring support layer
  • ‘No roll-off' SupportCore™ base
  • Simba ReGen™ base layer

Eleven layers of patented Simba technology

Eleven layers? And every single one plays their part in helping you sleep better, in the most sustainable way.

Breathable, anti-allergy covers

A soft, knitted sleep surface (which zips off for washing) keeps your mattress fresh and cool; an inner cover protects the internal layers when the top cover is in the wash.

Simba ReGen™.
It’s a Foam from Foam.

For Simba, a healthier planet is as important as restful sleep. And there’s no time to waste. Literally.

We’ve used certified, recycled fibres in our mattress covers, but recycling foam has always been trickier - there are only so many dog beds the world needs after all.

So we’re thrilled to have come up with Simba ReGen™, our new mattress base layer. It’s made from suitable, surplus foam and turned into a high-quality product created to strict density levels; all the foam used is CertiPUR® standard so it’s free of environmental pollutants and toxic materials.

So that’s less to landfill, AND less new resources… What a win.


It definitely has the ‘edge’

Our innovative edge-to-edge springs are at the heart (or should we say base) of this, up to 68% less foam mattress. Up to 1000 of them work together to provide robust support right across the mattress, allowing you to sleep up to the very edges with no dipping. Made from tempered steel, these deep, barrel-shaped springs also increase breathability through the mattress and are encased in fabric to ensure they respond independently to pressure.

All that, and they can still be compressed and rolled to enable boxed delivery.

So not all great engineering is building and bridges.
