Discover naturally inspired comfort with the Simba Earth Source Mattress. Its spring-support system works with carefully chosen wool and other natural fibres to deliver a responsive, comfortably cushioned sleep surface.
Layered British and resilient Hampshire wool adds soft cushioning while helping the mattress retain its comfortable shape over time. A smooth, plant-derived viscose cover with invisible tufting creates a refined, soft and beautifully inviting everyday sleep surface.
An Aerocoil® layer responds to body contours, supported by a CoreMax™ base with up to 1,000 zoned barrel springs in king size. Together they provide tailored, edge-to-edge support using natural materials and advanced mattress technology.
