1. A cushion including comprising:
a first cushion portion; a second cushion portion; and a connecting portion interconnecting the first cushion portion and the second cushion portion such that the first cushion portion and the second cushion portion are brought to an open position to unfold the cushion, the first cushion portion and the second cushion being movable to a closed position to fold the cushion along the connecting portion into a generally rectangular parallelepiped, wherein the first cushion portion comprises: a first surface defining one side of the generally rectangular parallelepiped; an inclining surface extending obliquely from one end of the first surface; and a second surface extending at a generally right angle from an opposite end of the first surface, wherein the second cushion portion comprises: a first surface defining another side of the generally rectangular parallelepiped different from the one side; an inclining surface extending obliquely from one end of the first surface of the second cushion portion; and a second surface extending at a generally right angle from an opposite end of the first surface of the second cushion portion, wherein the connecting portion is provided along one corner of the generally rectangular parallelepiped and interconnects the one end of the first surface of the first cushion portion and the one end of the first surface of the second cushion portion, wherein the inclining surface of the first cushion portion and the inclining surface of the second cushion portion are both planar surfaces, and wherein the cushion has three modes, the three modes being a folded mode, a first unfolded mode, and a second unfolded mode, the folded mode being a mode in which the cushion is folded into the generally rectangular parallelepiped with the inclining surface of the first cushion portion and the inclining surface of the second cushion portion contacting each other, the first unfolded mode being a mode in which the first surface of the first cushion portion and the first surface of the second cushion portion are both in contact with the ground, and the inclining surface of the first cushion portion and the inclining surface of the second cushion portion are opposed to each other, and the second unfolded mode being a mode in which the inclining surface of the first cushion portion and the inclining surface of the second cushion portion are both in contact with the ground, and the first surface of the first cushion portion and the first surface of the second cushion portion are opposed to each other. |
