The present invention relates to a cushion body structure capable of vacuum shaping and having buffering capacity, comprising a shaping bag body, a plurality of particles and a buffering bag body. The shaping bag body is integrated with one corresponding side of the buffering bag body, wherein an inner surface of the shaping bag body is fixed with positioning elements at corresponding positions spaced from each other, so as to partition the receiving space of the shaping bag body into a plurality of positioning spaces. The particles can be filled in the positioning spaces and movable in the positioning spaces. The buffering bag body is also made of a gas-impermeable material. The shaping bag body and the buffering bag body are respectively provided with an air channel to allow a gas suction device to evacuate gas from the shaping bag body through the air channel, and to allow a gas injection device to inject gas into the buffering bag body via another air channel.本發明係一種能真空塑形且具緩衝能力之墊體結構，包括一塑形袋體、複數個顆粒及一緩衝袋體，且該塑形袋體與緩衝袋體相對應之一側面係連接成一體，其中，該塑形袋體之內表面在彼此間隔且相對應之位置，分別固設有一定位元件，以將該塑形袋體之容納空間區隔成複數個定位空間，該等顆粒能被填裝在該等定位空間中，且能在該等定位空間中移動，該緩衝袋體亦由不透氣材料製成，又，該塑形袋體與緩衝袋體分別設有一氣道，以供一抽氣裝置經由該氣道對塑形袋體進行抽氣，且供一注氣裝置經由另一氣道對緩衝袋體內注氣。
