The Sareer Birch Mattress is built with your comfort-and the planet-in mind. It's filled with a smart mix of three advanced polyester fibres, including a clever elastic fibre that helps it keep its shape and bounce. The blend of coarse and fine fibres gives you just the right mix of support and softness, helping your body rest and recover every night. What makes it even better? The polyester filling is naturally flame-retardant, so there's no need for added FR chemicals. It's also 100% recyclable when you're ready to move on, meaning your mattress can be upcycled into something new instead of ending up in a landfill. A generous layer of memory foam-style comfort gives the Birch a medium feel-just the right balance between soft and supportive. It gently moulds to your shape, spreading your weight evenly and helping ease pressure on your joints for a more restful night. Tried, tested, and built to last-the Birch is all about comfort that doesn't cost the Earth.
