Hypnos Alcester Ortho Extra Mattress - EU King

• Damask cover. A finely woven, durable fabric that feels soft to the touch. It doesn't retain heat, which means it stays cooler against you through the night.
• Cotton. Breathable cotton fibres that wick away moisture. In practice that keeps you dry and cool rather than clammy.
• Solotex™. A filling engineered from recycled plastic, so it's an eco-friendlier choice. It's extremely durable and cuddles body contours for a slightly softer feel over the firm springs.
• Pocket Springs. 1,200 ReActivePro 6-turn pocket springs with tighter spring resistance. That means a more supportive surface that still adapts to your unique shape, weight and movement.
