This quilt adopts loose leaf design, and users can use it directly without quilt cover. It is very convenient to clean the quilt without taking off the quilt cover. The production process adopts fixed-point quilting design. The exquisite quilting process maximizes the fluffy degree of silk, in which the needle spacing is close and symmetrical to ensure the fit between the internal silk and the fabric, so as to realize washability and durability. Considering the climate and temperature changes in different regions, the designer chose the thickness of silk suitable for the four seasons.
