Disclosed is a cushion structure, which includes a box, a holding
structure and a first cushion therein. The first cushion includes a
bearing part, two buffer parts and two supporting parts. The buffer parts
are joined with two sides of the bearing part to form a first angle and a
second angle. The supporting parts are joined with opposite sides to the
sides of the buffer parts joined with the buffer parts to form a third
angle and a fourth angle. The cushion structure further includes a second
cushion disposed parallel to the first cushion between the box and the
holding structure. Alternatively, the second cushion can be disposed
opposite to or superimposed over the first cushion between the first
cushion and the holding structure. Both the first and second cushions can
be formed as one-piece.
