From B Nott comes a luxury range of intelligent seasonal duvets and pillows. For the perfect sleeping environment all year round, this set includes a 4.5 tog summer duvet and a 9 tog autumn and spring duvet which can be used together as the equivalent of a 13.5 tog winter duvet. Made in conjunction with the world leader in man-made cellulose fibre technology, the Lenzing Group, and ADVANSA, one of the leading producers of polyester-based polymers in the Middle East and Africa, B Nott have searched far and wide for optimum fabrics. TENCEL is a special fabric made from wood that absorbs humidity while the unique monopolymer Suprelle Fresh promotes good air circulation. Specific tests carried out at Germanyfts Hohenstein Institute revealed that a duvet made with Suprelle Fresh and TENCEL improves moisture vapour uptake by 57% compared to a standard duvet.
