Layer Details
Comfort Layer
Soft white synthetic fibres sit at the top, which means a cosy initial feel rather than a firm, flat surface. They're durable and resilient, designed to hold their shape over time.
Support System
Traditional open coil springs are interlaced and joined in a lattice design, which means your weight is distributed evenly across the bed. That helps relieve built-up pressure and supports spinal alignment, the core job of an orthopaedic mattress.
Cover
A knitted cover gives a soft, warm finish. It also enhances airflow and is breathable, which helps if you run a little hot at night.
