A sorbent cushion includes a body, and the body includes an osmosis top piece, and an osmosis bottom piece. The top piece and the bottom piece are symmetrical relative to a transverse line or a lengthwise line of the sorbent cushion, such that any one lengthwise portion of the sorbent cushion faces forward or backward can be connected with a user's body. The sorbent cushion further comprises a sorbent piece located between the top piece and the bottom piece.
