The present invention using inexpensive, available feather and a foamed synthetic resin piece, insulation and or breathability feather has, it is possible to take advantage of the characteristics of low resilience with a foamed synthetic resin, while rustling feather and sound generated, providing a cushioning material capable of suppressing sag rapid foam plastic pieces. The bag-shaped cloth 1, and a cushion material and a feather 2 and the foamed resin piece 3 is sealed in a mixed state. These weight percentages, expandable resin strip: Feather = 55 :45- 70:30 range, and foam pieces each of the longest sides when it is from the base of each feather and 1 the average length to the tip or diameter or average length of the major axis, it is preferably 0.3 to 0.7. |
