This is a closed stitched duvet (box stitches) and the filling is fixed into different small boxes. They are box stitched to keep the luxury fillings evenly spread throughout the duvet. Every box is stitched all over the cover. The filling can not move and so the Box-Step Duvets will always maintain a uniform distribution of the filling. This stitching pattern gives the down very little room to puff up or "loft". This means there is less trapped air which allows not to be as warm as the following models. Mussner duvets are individually handcrafted and filled with premium quality of Goose Down on the inside and the finest 100% down-proof cotton ticking on the exterior covering to prevent escape of the feather and down.
