Our organic latex is certified by the Global Organic Latex Standard (GOLS). This certifications monitor production from field to factory ensuring fair treatment of workers and the highest environmental standards are upheld.
Meet our most eco-friendly mattress ever, with just half the carbon footprint of traditional hybrids. It’s the cool, comfortable combo of natural, organic materials with technologically advanced ones.
Technology isn’t always about new materials. It’s about finding new ways to use established ones, like Latex; a natural by-product of the rubber tree, Latex has been around for centuries. With its excellent properties of elasticity, it offers superb body support and pressure distribution, but it’s also a renewable, bountiful, and biodegradable material, as well as naturally anti-microbial.
All of which was music to our ears.
Because we’ve been searching for a more sustainable comfort layer to partner our ingenious Aerocoil springs, and latex is the answer. We’ve made sure this natural beauty meets the Simba standard of heat control and comfort by adding perforations to encourage airflow, and graphite to absorb excess heat; we’ve also added a thick, anti-allergenic barrier layer between the latex and the cover.
We're also delighted to use Global Organic Latex Standard (GOLS) certified latex; this is a body which regulates natural rubber products all the way from field to factory, promoting sustainable and responsible practices such as pesticide-free farming, the correct disposal of wastewater and safe working conditions.
Cotton is naturally breathable and cooling, and it's a soft, comfortable and durable material for mattress covers. But conventionally grown cotton has a much more negative impact on the environment than you might think.
That's why we took the decision to make the Simba GO's cotton cover from certified recycled cotton. This certification regulates organic, natural textiles during their entire production, from the chemical-free growth and safe harvest of raw materials, through to responsible manufacturing such as the banning of dangerous dyes and fair employment practices such as a living wage.
Along with natural bleaching techniques and a botanical fire-retardant treatment, it really is the best possible cotton we can find.
As environmental stewardship goes, there's nothing better.
Our patented micro springs are so strong that they offer unrivalled support, but also so small that we can position them unnoticed nearer the top of the mattress, where they limit motion transfer and help prevent overheating.
They are up to 2,000 of these steely, recyclable gems in the Simba Go, tucked under the latex layer where they offer increased air circulation and ultra-responsive comfort - flexing gently in response to you and your partner's every move, offering personalised support to one without disturbing the other.
While all Simba mattresses are 100% recyclable, we’ve designed the Simba GO to be even easier to disassemble and recycle. That's why, for example, there is no chemical glue in the Go mattress; it’s potentially damaging and polluting, making further recycling much, much harder.
Our commitment to recycling also lies behind our passion for Simba Renew™; it’s a soft, anti-allergenic and breathable layer, but it’s made from as much as 75% recycled yarns, with a few new fibres to ensure optimum durability. So while it may be a man-made material, it represents us all the opportunity to be more sustainable in everything we make and use.
It’s our first step towards being circular.
Our Supportcore™ base features up to 900 pocketed springs, but by varying the diameter of the spring wire we’ve been able to create 5 support zones for the parts of your body with more specific needs, such as your shoulders and hips. The same technology allows effective edge-to-edge support, thanks to firmer rows of springs at the edges of the mattress.
Using a spring base rather than foam also encourages even more airflow through the mattress. But what makes this pocket spring base so unique, and so Simba, is its sustainability factor: it’s 100% recyclable because there’s nothing in it apart from steel and recycled fibres. But we’re even more proud that it’s the only pocket sprung base that can be rolled and boxed, which makes this mattress more efficient to transport and reducing its carbon footprint.
