摘要： A cushioning element includes a hollow elastic body, a plurality of first columns, and a plurality of second columns. The hollow elastic body includes a first side wall and a second side wall, where the first side wall includes a first inner surface, the second side wall includes a second inner surface. The first columns are disposed on the first inner surface, where each first column includes a first extending end and a first side surface, and there is a first distance between the first extending end and the second inner surface. The second columns are disposed on the second inner surface, where each second column includes a second extending end and a second side surface, there is a second distance between the second extending end and the first inner surface, and the second side surface and the first side surface are at least partially in contact with each other.
