Our aim with the Earth range was to design the best natural mattress, UK made, as sustainably as possible; the range combines some of Nature’s best materials and our signature tech, to provide a more natural mattress with no compromise on comfort.
In fact we’re thrilled with the result: this natural fibre mattress range gets as close to being a hypoallergenic mattress as we think we can get, given that the bio-based, responsibly processed materials we use (such as cotton and wool )are breathable and therefore naturally deter potential allergens from setting up home in them. The signature spring technology we use means it’s a chemical free mattress too.
We think our Earth mattresses are ideal for children; they feature some of Nature’s best materials and our usual signature tech, to provide a more natural mattress with no compromise on comfort – plus we believe the combination of these two ‘ingredients’ contributes to this being a non-toxic mattress.
But for raised beds or bunk beds we recommend our Hybrid® Kids’ mattress; it’s a UK single size but has a shallower depth (16cm) to meet safety regulations. We’ve also designed our own double-sided cot bed mattress, which offers a firm, flat sleeping surface for newborns and a softer cushioned side for babies and toddlers needing edge-to-edge support after 12 months.
They’re the best of both worlds! Our Hybrid® mattresses combine our patented Aerocoil® springs with our Simbatex® foam, but our Earth mattresses feature these unique springs with cushioning, natural materials instead of foam; they’re designed to bring you the tailored support of springs with the superb comfort and breathability of cashgora wool, Hampshire wool and silk.

Overheating is one of the most common causes of poor sleep disruption. But the naturally breathable materials in our superb Earth mattresses are designed to help deliver a fresher night’s sleep; our patented Aerocoil® micro springs are also designed to gently push air through the mattress to help prevent overheating.
All the Simba mattresses for sale are made in the UK. We love to stay local wherever we can, so that we can support the local communities.
All our mattresses are suitable for recycling by specialist providers, but our Earth mattresses are easier to recycle because they’re glue and foam free.
We also offer our own Simba Mattress Recycling Service; for a small fee we’ll collect your old mattress for you and make sure it’s properly recycled - any brand, any size, no Simba purchase necessary.

Yes, have a look at our Simba Refurbished range, although do remember availability may vary. We thoroughly refurbish and every mattress returned to us if we can; it’s kinder to the planet to give them new life whenever we can, and it’s a good way to make our unique sleep tech more accessible to everyone. That mattresses unsuitable for refurbishing are recycled.

Absolutely. We’re confident our high-quality, Hybrid® mattresses will go the distance, so they all come with a 10-year guarantee; Simba certified Refurbished mattresses include a 1-year guarantee.
Our Earth mattresses need rotating twice a year after the first few months; this keeps the natural mattress fillings more comfortable for longer.
We do recommend one of our Mattress Protectors however; they’re made from soft, quilted cotton and are designed to help protect your mattress from accidental damage or spills.
Yes. All Simba mattresses are delivered free to most UK postcodes: while our Hybrid® range arrives vacuum-packed and boxed, our Earth mattresses arrive flat-packed and ready to use.
Returns are also free within our 200-nights trial period. If you decide it’s not for you within that time, we’ll collect it from you free of charge.
We have a range of bed frames to suit every need, from our clutter-clearing Ottoman bed bases to our beautifully simple Wooden beds. And because sleep is personal, you can choose your fabric, headboard design and desired storage on selected premium beds.
