PROBLEM TO BE SOLVED: To provide a down-filled quilting easily fitted to the body of a person in sleep by increasing the density ratio of the filling amount of filler (down) in cubes in an all-side circumferential edge part more than the filler (down) of cubes in a central part, reducing a pressure applied to the body, preventing drafts and increasing the stability in sleep by reducing the density of the filling amount of the down in the cubes in the central part. SOLUTION: This down-filled quilting is divided into lattice of the all-side circumferential edge part 2 and the central part 3 by quilting the font/rear clothes, and the divided cubes in the central part 3 are lighten and increase the bulk by reducing the density ratio of the filling amount of the down, while the divided cubes in the all-side circumferential edge part 2 become heavy by increasing the density ratio of the filling amount of the down.
