Hypnos Winslow Luxury Wool Mattress - EU King

• Sleep surface. A soft cotton sleep surface sits at the top. Cotton is naturally breathable, which means the layer closest to your skin stays comfortable rather than clammy.
• Wool fillings. Beneath the cotton sit eight fleeces of wool that regulate body temperature through the night, so you feel warm in winter and cooler in summer. The wool is sustainably sourced and traceable to its origins through Hypnos' partner Red Tractor.
• Support system. The base is 1,200 ReActivePro 6-turn pocket springs, which respond to your weight and position to relieve built-up pressure. Triple Edge Protection adds three rows of firmer springs and rod edging around the spring unit, which means a firmer, more usable edge.
