Engineered by nature. Our wool range weaves together the cosy comfort of British Wool with Silentnight's unrivalled experience. It combines great craftsmanship with a flexible and breathable material that keeps you cool in the summer and warm in the winter. Our British Wool comes from Cheviot sheep, their soft yet sturdy fibre is perfect for mattresses, offering natural body and bounce for lasting comfort and support. Our British Wool comfort layer is then enhanced further with Platinum comfort, this layer is 10x more breathable than memory foam but has the same amount of pressure relief. Offering cooling, cocooning, no compromise comfort. Additional durability is then applied through a layer of Coir, this fibre comes from coconuts and is a natural resource, its robust and elastic like qualities ensure your mattress retains its shape for longer. The sleep surface and sides are covered in natural Tencel™ Lyocell fabric. This silky feeling, soft touch material is woven to allow airflow and moisture transportation away from the sleep surface. This aids temperature regulation and gives it a naturally cool touch - perfect for hot sleepers. This supreme, supportive mattress features 600 Mirapocket springs, which adjust to your movements throughout the night, offering exceptional tailored support that's personal to your body shape. The Mirapocket springs are further combined with 1000 mini pocket springs for additional comfort and increased breathability. This product is foam free and uses natural flame retardants.
