PROBLEM TO BE SOLVED: To provide a cushion structure having no bottom touching feeling and reducing settling in the cushion structure having thin-walled and long partitions disposed in parallel into a grid. SOLUTION: This cushion structure is formed by disposing the thin-wall and long partitions buckled by being pushed in parallel into the grid. The partition comprises, at least, one type or more rubber cross-linked substances (cross- linked rubber) selected from natural rubber and synthetic rubber, and the partition is the cushion structure having a hardness of shore A 20-40. The rubber is preferably rubber mixture including polybutadiene rubber of 10-20 mass%. Especially, it is preferable that the rubber comprises natural rubber of 40-80 mass%, polyisoprene rubber of 10-40 mass%, and polybutadiene rubber 10-20 mass% (the total of the three are 100 mass%). Reactive plasticizer, a reinforcing material, and blooming preventing agent may be mixed in the cross-linked rubber. This cushion structure is suited to a bed cushion. COPYRIGHT: (C)2003,JPO
