5ingenious things you should know about Super King Size | Foam & Springs | Simba Sleep Hybrid®

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…

The Simba Aerocoil®
microspring comfort layer

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 2,500 of these ingenious springs nestling in our 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

The fresh feel of
Simbatex® 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.

CertiPUR® Verified

CertiPUR® Verified

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.

 

Engineering new
ways to cut waste

For Simba, protecting the planet is as important as restful sleep.

We’ve used our expertise to reduce our use of energy and materials, and all our mattresses are 100% recyclable. To prove the point, we’re proud to tell you that any old Simba mattresses returned to us are refurbished or recycled; they never go near a landfill site. Ever.

On top of that, all our mattresses are made here in the UK so unlike other brands they don’t have a long journey to make it to you, and all our packaging is up to 60% recycled, from approved FSC sources, plus 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.
