This luxurious 4-season duvet combines 2 different filled parts, which can be joined together by push buttons. The lighter part for summer, the denser filled one for autumn and spring, and both together for a warm winter duvet. It has a wonderfully soft touch thanks to its unique composition with Tencel Lyocell. Also, excess moisture is absorbed and released very quickly. This dry sleeping environment prevents the development of bacteria and dust mites. - 4 seasons duvet - Moisture regulating - Super soft touch - Anti-allergic - Cover: Tencel Lyocell Satin - Filling 60% Tencel Lyocell - 40% Climate fibre - Washable 60° degrees
