Hypnos Cawthorne Deluxe Mattress - EU King

• Soft White Fibres. Soft synthetic fillings sit at the top to create a cosy feel. They're durable and resilient, which means the surface should hold its shape rather than flattening quickly.
• Solotex™ fibres. A plush, highly breathable layer that increases airflow through the mattress. This helps dispel heat and moisture, so the sleep surface feels fresher through the night.
• eOlus™ fibre layer. Made from recycled material, this layer adds cushioning with a slightly firmer feel. It's there to keep you supported and comfortable all night.
• Dual density polyester fibre pad. One side adds an extra touch of comfort for you, the other supports the spring unit. Together they help distribute your weight evenly across the mattress.
• Pocket Springs (ReActive™). 1000 ReActive springs sit in individual fabric pockets and move independently. That means they respond to movement and target the areas of your body that need support.
