Goes like a dream with
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.

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…
These tiny cones of comfort will transform your sleep
The key to our incredible, upper comfort layer, and our pride and joy, these springs are 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 can provide the comfort you need. But 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. So you’ll find up to 2000 of these ingenious springs nestling in our Hybrid mattress; their clever, conical shape means they compress inwards rather than sideways, preventing the transfer of motion to adjacent springs. The result? Tailored support for each partner, without one disturbing the other. And as they compress they gently puff air through the mattress, providing extra airflow and heat control. But we didn’t stop there. We’ve also fine-tuned them to create thirteen zones of differing resistance, to perfectly support the parts of your body that need more cushioning such as hips and shoulders.
So now you know. Small really is beautiful.
Traditional memory 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 68% reduction of foam in our Hybrid mattresses.
And you thought foam was just, well, foam? Not in our book.
Six layers? And every single one plays their part in helping you sleep better, in the most sustainable way.
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 mattresses are sourced and made in state-of-the-art UK mattress factories.

For more info, please head to our FAQ.
The top cover is removable and washable (washing instructions included). Wash at 40°C on a reduced spin cycle. Do not use chlorine bleach. Do not tumble dry, iron or dry clean.
The grey base fabric can also be cleaned with a soft, damp and clean cloth using small circular motions. Using a mattress protector could help extend the life of your mattress.
Carbon neutral delivery is free as standard to most of the UK. In most cases, we deliver seven days a week when you pick a date at checkout. Due to the weight of this mattress we strongly recommend delivery to your chosen room and that you ensure children are kept at a distance from delivery and unboxing. If you choose to return your mattress during your 200-night trial, returns are also free in most of the UK.
If you decide the Simba Hybrid® Mattress is not for you, just give us a call during the trial. We’ll arrange a free collection and refund the cost of your mattress or any financing payments made (not including delivery charges). And don’t worry - we wouldn’t dream of asking you to get it back in the box.
Every Simba mattress comes with a ten year guarantee. If it fails during that time, we’ll exchange it for a brand new one.
Our foams have all received the CertiPUR® label, meeting the requirements of unwanted chemicals in foams. No destructive agents of ozone, heavy metals, mercury or lead have therefore been used for their manufacture. They are also perfectly safe and suitable for everyone.
For Simba, a healthier planet is as important as restful sleep. And there’s no time to waste. Literally.
We’ve used GRS 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.

These are some of the common bases used with our mattresses:
Slats
(evenly spaced boards)
Sprung divan or box spring
(frame with springs set in)
Any supportive bed base — including adjustable — is suitable, as long as that's its dedicated purpose. The Hybrid Mattress is at its best on a sprung or rigid divan or slatted bed frame.
If you have a slatted base, quickly whip out the tape measure to check the slats aren't more than three inches apart.
