Better sleep means a better you. And the Simba® Natural Hybrid® Source Mattress helps you enjoy a seriously upgraded quality of sleep thanks to incredible comfort and support technology from the leaders of sleep innovation. Wake up refreshed and ready to take on every day as the best version of you with the help of this eco-conscious, durable sleep surface.

Natural comfort thanks to five layers of cushioning wool

Two layers of plush Hampshire wool plus three additional layers of British wool don't just provide full-body cushioning that eases pressure across your joints. They also help to regulate your temperature and keep you as cool, fresh, and comfortable as possible. Highly breathable, these layers also wick away excess moisture in the night, meaning you enjoy a night of rest free from overheating and stuffiness.

Precise support from British-made steel springs

For ultimate support, Aerocoil™ mini springs are precision-made from British steel. These small but mighty springs ensure every single pressure point across your body is supported, whether you sleep on your front, back, or side. With a medium-firm feel, this support system also provides orthopaedic comfort, known for keeping your hips and shoulders in line with your spine to ease back aches and pains.

Deep, durable support that's glue-free and breathable

A CoreMax base offers deep, long-lasting support from the very foundation of the Simba® Natural Hybrid® Source Mattress. A layer of individually pocketed springs, this CoreMax base targets precise tension relief to the heaviest parts of your body, helping to ensure your spine doesn't bend too far out of alignment. Made from British steel and with a glue-free construction, this base promises durability that's better for you and the planet.

Sustainable sleep with eight carefully crafted layers

With an incredible eight innovative layers, this mattress is one of the very few that does exactly what it says on the tin: provides comforting, supportive pressure relief that refreshes and rejuvenates you as you sleep. The final layer is the viscose plant-based cover made using sustainable, plant-based fibres for a soft, silky feel and a more breathable sleeping environment.

Sizes to suit any space with support for any sleeper

With a 28cm depth and available in double, king, or super king sizes, this mattress from the Simba Natural Hybrid® range is ideal for your master bedroom, spare room, or teenager's bed, and sits stunningly on any type of bed frame.
