PROBLEM TO BE SOLVED: To prevent down from being held around partition chambers even when down is moved in the partition chambers to make the down fit to a body by forming circular partition chambers of the same size and aligning them along lengthwise in a down quilt. SOLUTION: A rectangular down quilt 1 is formed by aligning circular partition chambers 3 of the same size filled with down lengthwise and breadthwise. The longitudinally adjacent partition chambers 3 are brought into contact with each other, and an interval 4 is provided between the breadthwise adjacent partition chambers 3 to separate the partition chambers 3 from each other. In addition, partition walls 9a-9d are formed along a line connecting the middle point 6 of one long side 5 to the corresponding middle point 8 of the other long side 7 except the inside of the partition chambers 3. Furthermore, the partition chambers 3 aligned along one short side 10 are connected to both ends 10a of the short side 10 via partition walls 12a-12d, and the partition chambers 3 aligned along the other short side 11 are similarly connected to both ends 11 of the short side 11 via partition walls 13a-13d.
