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
These are the key to our incredible, upper comfort layer; they’re our pride and joy. They’re smaller and slimmer than the typical, rather tall and bulky bed spring, because they’re made from super-strong titanium; using this magic metal means even a micro size (25mm high with a thickness gauge of 0.9mm, which is the size of a very thin paperclip) gives you the support you need, but being so small and fine you won’t feel a single one.
You’ll find up to 1,500 of these ingenious springs nestling in our essential mattresses; each individual Aerocoil® spring flexes gently in response to you and your partner’s movements, offering personalised support to each of you without disturbing the other. And as they compress and extend with you, they gently push air through the comfort layer, helping to keep you at just the right temperature.
So now you know. Small really is beautiful.
Traditional memory foam
For pitch perfect temperature control
Being too hot at night is an absolute no-no for great sleep. That’s why we designed our fantastic Simbatex foam; it’s an ‘open cell’ foam, which allows thirty times the airflow of memory foam (that’s almost breezy for a bed). On top of that our sleep scientists have infused it with a naturally occurring mineral called graphite; this draws heat away from your body.
And you thought foam was just, well, foam? Not in our book.
Four layers? Yes. And every single one has a part to play in helping you sleep better.
All Simba mattresses are sourced and made in state-of-the-art UK mattress factories.

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.
All the foam we use in our mattresses is CertiPUR® recognised, meaning both the materials it contains and the emissions it releases have been independently and rigorously assessed; CertiPUR® foam is verified as free from CFCs and other ozone depleting substances, and ensures lower emissions to protect indoor air quality.
In addition, you can rest easy knowing that all CertiPUR® foam is free from added phthalates and harmful metals such as mercury or lead, and includes safe, non-toxic levels of fire retardants.
For Simba, protecting the planet is as important as restful sleep. We’re proud to be the first UK-born sleep brand to be awarded certified B Corp™ status.
Our official B Corp™ accreditation is an accolade that is only awarded to select businesses that promote social and environmental change through how we work and operate, something we consistently strive for.
We’ve used our expertise to reduce our use of energy and materials, and all our mattresses are 100% recyclable. To prove the point, any old Simba mattresses returned to us is refurbished or recycled; they never go near a landfill site. We have now opened our own state-of-the art, non-for-profit recycling service and accept any brand of mattress with no purchase necessary to use the service
All Simba mattresses are made in the UK in zero waste factories, reducing air miles in the process. Plus, our packaging is up to 60% recycled, from approved FSC sources, and all our deliveries are 100% carbon neutral. We’ve even worked out that we can use any excess foam in things like carpet underlay or pet beds rather than letting it go to waste.
We reckon that’s not half bad for a bunch of sleep experts like us.
We're experts in the science of sleep, and over a million customers have already trusted us to give them the best night's sleep they've ever had.

These are some of the common bases used with our mattresses:
(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.
