Simba® Natural Hybrid® Source Mattress

Description

Better sleep leads to a better you—and the Simba® Natural Hybrid® Source Mattress is designed to elevate your rest with advanced comfort and support. Created by pioneers in sleep innovation, this eco-conscious and durable mattress helps you wake up refreshed, recharged, and ready to take on the day.

Natural comfort thanks to five layers of cushioning wool
Two layers of plush Hampshire wool, combined with three additional layers of British wool, provide exceptional full-body cushioning to ease pressure on your joints. Naturally breathable, these layers help regulate temperature and wick away moisture, keeping you cool, fresh, and comfortable throughout the night.

Precise support from British-made steel springs
Aerocoil™ mini springs, crafted from British steel, deliver targeted support to every pressure point. Designed to adapt to all sleeping positions, this system offers a medium-firm, orthopaedic feel that helps align your hips and shoulders with your spine, reducing aches and promoting healthier sleep posture.

Deep, durable support that’s glue-free and breathable
At the foundation, the CoreMax base features a layer of individually pocketed springs for deep, reliable support. This structure relieves pressure from heavier areas of the body while maintaining proper spinal alignment. Built from British steel with a glue-free design, it enhances durability while supporting a more sustainable approach.

Sustainable sleep with eight carefully crafted layers
With eight thoughtfully engineered layers, this mattress delivers consistent comfort and support night after night. The top layer features a soft, silky viscose cover made from plant-based fibres, improving breathability while offering a more sustainable sleep surface.

Sizes to suit any space with support for any sleeper
Measuring approximately 28cm deep and available in double, king, and super king sizes, the Simba® Natural Hybrid® Source Mattress is a versatile choice for any bedroom—perfect for master suites, guest rooms, or growing households, and compatible with a wide range of bed frames.
