The Marshmallow Bio-based Quilt breaks with the traditional 100% polyester filling and is made from biodegradable raw materials - mugwort, soya, and corn - to reach a 51% bio-based filling. It features a scientific golden proportion to secure intelligent temperature control at 31.6 degrees Celsius, ensuring breathability and comfort. The quilting design conforms to the sleeping positions of the human body, which does not let air in when you roll over. The snap buckle allows for free combination, satisfying users' individual needs for thickness and size to achieve an ideal sleeping experience.
