Sleep should be simple. It is one of the most important elements of our life, where we spend a third of our reality, at one with the universe, in peaceful, natural, and comforting state. But often it isn’t. We wake up too hot, too cold, or just not rested.
Cue the Simba Hybrid™ Duvet – designed to make our sleep experience better with soft materials, innovative, futuristic technology, and a thoughtful approach to comfort and sustainability. At its heart is Simba Renew Bio™ – a soft, down-like filling made from recycled plastic bottles. It’s light, airy, and gentle, akin to resting on a cloud. Unlike heavy or stuffy duvets, it allows air to move freely, giving us warmth without overheating. It keeps us cosy but dry, which helps us sleep deeper and wake up feeling refreshed.
Underneath, the duvet has Stratos® technology. This smart material responds to our body temperature as we sleep. If you start to get too warm, it cools you down. If you feel a little cold, it releases warmth. You might not notice it working, but our bodies do. It’s like having a quiet assistant that helps you stay just right, all night long.

The cotton cover is just as thoughtful. It’s made through the Better Cotton initiative, which supports more sustainable farming and fairer working conditions. The result is a soft, breathable fabric that feels good on your skin – and does good in the world.
Every part of the duvet is made with care. It’s stitched in a square pattern to stop the filling from shifting or clumping. That means no cold corners or lumpy patches – just even warmth from edge to edge. It’s machine washable (in a large machine) and dries quickly thanks to the lightness of the filling.
You’ll also find small touches that make a difference. A foot-end label so you always know which way is up. A QR code to help you care for your duvet or recycle it when the time comes. Practical, helpful details, built in without fuss.

Simba doesn’t just make products, they are a brand that actually stands for something. As the UK’s first B Corp sleep brand, they believe in business that’s better for people and the planet. Their duvets are made to last, and can be refurbished or recycled through certified programmes. It’s comfort that considers the bigger picture.
And yes, this duvet works all year round. Summer or winter, the smart temperature control and breathable materials adapt to you. No need to swap it out for another. One duvet, every season.
The Simba Hybrid™ Duvet is not just about sleep – it’s about rest that feels right. Gentle warmth, cool touch, soft fabric, and smart design. All working together to help you drift off easily and wake up ready for life. It’s simple. But deeply thought through.
