"Designed for dependable, everyday comfort, the Nexus Mattress Comfort Chelsea open coil sprung mattress offers a well-balanced medium feel to suit a wide range of sleeping styles. Its construction is carefully engineered to promote correct spinal alignment, providing consistent cushioning while helping to relieve pressure across key areas of the body for a comfortable night’s sleep. At its core, a durable open coil spring system is formed from a continuous wire to create a supportive and resilient foundation that remains lightweight and easy to handle. A traditional tufted finish helps secure the internal layers in place, supporting long-term comfort and shape retention. The sleeping surface is covered in a high-quality knitted fabric chosen for its softness, breathability and gentle stretch, while the single-sided design provides a dedicated sleep surface. Underneath, a non-slip base fabric helps keep the mattress securely positioned on the bed frame.
