Sareer Eco Alder Super King Size Coil Mattress

The Sareer Alder Mattress brings together smart sleep tech and planet-friendly materials for a feel-good rest—night after night. It’s built with a reliable open coil spring system and filled with a special blend of three high-performance polyester fibres, including one that helps the mattress hold its shape and bounce back over time. Sustainability is at the heart of the Alder. The polyester filling is 100% recyclable at the end of its life, so when you’re ready to move on, it can be upcycled into something new—not headed to landfill. Designed with both coarse and fine fibres, this mattress offers great support and recovery, helping you wake up feeling refreshed. It's been put through serious testing to make sure it stays comfy and supportive for years to come. Better yet, it's naturally flame-retardant without any added chemicals—and thanks to its clever design, it helps keep your spine aligned and stops that annoying roll-together feeling. That means you and your partner can enjoy uninterrupted, comfortable sleep every night.
