The high quality hollowfibre filled duvet is lighter & more luxurious than standard hollowfibre duvets. The 100% cotton cover means you will experience a warm & comfortable nights sleep. ' Cotton Touch' is designed to keep you snug & cosy & add that 'tucked-in' feeling whilst offering outstanding value without any compromise on quality. The All Seasons Duvet features two duvets in one (9 Tog + 4.5 Tog). Which can be separated during the warmer months to create your perfect duvet.
