An sorbent article comprises a single waist belt and a sorbent cushion detachably connected with the waist belt. The waist belt winds around a user's waist, and the sorbent cushion includes a osmosis top piece, a osmosis bottom piece, and a sorbent piece located between the top piece and the bottom piece. The sorbent cushion includes a front portion, a back portion, and a crotch portion along a lengthwise direction. The corners of the front portion and the back portion have connecting devices respectively, and the connecting devices can be connected with the waist belt. One of the front portion and the back portion has a waist elastic element which is arranged symmetrically relative to a lengthwise center axis, and the waist elastic element is transversely extended between the two connecting devices. The waist elastic element has a retracted state and a extended state. In the retracted state, the top piece or/and bottom piece is folded. In a fully extended state, the folded top piece or/and bottom piece is pulled to be horizontal. In the fully extended state, the elastic force of the waist elastic element is between two newton and seven newton一種吸收性物品，包括單獨腰帶和與腰帶可拆卸地相連的吸收墊，腰帶環繞穿用者之腰部，吸收墊包括液體可滲透頂片和液體不滲透底片及位於頂片和底片之間的吸收芯，吸收墊沿著一縱向方向劃分為前部、後部和其間的襠部，吸收墊在前部和後部的每個拐角處分別透過連接元件與腰帶相連，吸收墊的前部和後部中的至少一個包括有沿著一縱向中心線對稱設置的腰部彈性件，且腰部彈性件橫向延伸於連接元件之間，該腰部彈性件能在收縮狀態和完全拉伸狀態之間移動。在收縮狀態，底片和/或頂片呈現折褶形狀，在完全拉伸狀態，底片和/或頂片的褶折被拉平，在腰部彈性件完全拉伸時，來自腰部彈性件的彈力位於2N-7N之間。
