A cushion for assisting the spine to relieve pressure in the positive position, comprising a cushion body, the cushion body comprising a seat surface, a bottom surface, a flange, and three pressure relief holes, and the flange is projected on the edge of the seat surface, A groove is formed between the flange and the seat surface, and the seat groove forms an open mouth on one side of the cushion body. The seat surface gradually slopes upward from the open mouth side and away from the bottom surface. The relief holes are arranged in a triangular shape and penetrate 2/3 of the thickness of the cushion body to help disperse the pressure in the pelvic cavity and provide better support. Three relief holes are provided at the bottom center of the three relief holes. The ventilation holes smaller than the opening area of the pressure relief holes penetrate the cushion body to provide better ventilation and comfort.一種輔助脊椎正位舒壓之坐墊，其包含一墊體，該墊體包含一座面、一底面、一凸緣、與三個減壓孔，該凸緣凸設於該座面的邊緣處，而於該凸緣與該座面之間形成一座槽，且該座槽於該墊體的一側向形成開放口，該座面自該開放口側逐漸向上傾斜而遠離該底面，該三個減壓孔排列呈三角形並深入該墊體2/3墊體厚度的位置，藉此輔助分散骨盆腔的壓力，並提供較佳的支撐力，且於三個減壓孔底部中心位置開設三個小於減壓孔開口面積的透氣孔，貫穿該墊體，以提供較佳的透氣性以及舒適度。
