The fine and dense fiber layer of the Feather绒 quilt core can effectively lock in air, forming a stable layer of stationary air, which can also block the cold for you even on cold nights, providing excellent warmth and cold protection, comparable to natural down quilts. Moreover, the Feather绒 has undergone sufficient silicone treatment and moderate crimping process, making the quilt core feel more outstanding. Even with long-term use, the fibers will not entangle with each other, always maintaining excellent fluffiness, without the occurrence of clumping or fiber loss, allowing you to enjoy a comfortable sleep for a long time. In terms of material characteristics, due to its chemical fiber nature, this Feather绒 quilt core has the advantages of being resistant to mildew and not breeding mites, greatly ensuring sleep hygiene. At the same time, the washable feature makes cleaning and maintenance easy, making daily management more worry-free, and the easy-to-store characteristics also save you space.

Among them, the 180×220cm size is suitable for a 1.5m bed, with a total weight of the quilt between 3.1 – 4 jin, and the filling weight between 2.1 – 3 jin. For a standard double bed, the size coverage is just right, lightweight and warm.
