Slumberdown Wonderful Wool Duvet in Single, Double, King and Super King sizes - 200 GSM Light Enjoy a deep, restful snooze with the Wonderful Wool Duvet by sleep specialists Slumberdown. Packed into the pure cotton cover is a 200 gsm 100% British Lowland Wool filling. A natural fibre renowned for comfort and durability, it’s perfect for helping you to achieve the sleep you deserve. These incredibly complex fibres act like a spring, resisting pressure and providing plenty of bounce back without flattening, while also helping to trap air, which is then circulated throughout. Not only does this enhance the insulation and warmth within, but it also prevents overheating. Natural moisture absorption ensures your sleep isn’t disrupted by sweating through the night. This moisture is then released through the day, when the atmosphere around is dry, so the quilt will help to keep your skin drier and more comfortable. Because it reacts to lots of different things, including the ambient temperature and even your natural body heat, the filling of the Wonderful Wool collection is a little too clever to be given a simple tog rating. The 200 gsm filling of this medium duvet is the equivalent to 3.0-4.5 tog blankets, though, so it’s ideal for summer slumbers, as well as naturally warm sleepers.
