A bed assembly for preventing from bedsore generation is provided and includes a bedplate, a plurality of elastic balls, a plurality of supporting members and a biasing force mechanism. The bedplate includes a plurality of holes corresponding to the elastic balls so that the elastic balls are respectively placed at the holes. Each of the supporting members includes a connecting portion and a forced portion. The connecting portion connects with the elastic ball and the forced portion is passing through the hole. The biasing force mechanism disposed at the bottom of the support members, and respectively contacts with the forced portion to drive the connecting portions and the elastic balls to move. When a user lies on the elastic balls, the biasing force mechanism respectively supplies the force to the forced portion to drive the connecting portion and the elastic balls to move so as to massage the user’s body thereby achieving the purpose of the anti-bedsore.一種防褥瘡之床組結構,包含:床板、複數彈性球、複數支撐件以及施力機構。床板包含複數孔洞,複數彈性球可對應複數孔洞置放。各支撐件包含連接部以及受力部,連接部連接彈性球,而受力部則貫穿於孔洞。施力機構設置於各支撐件的下方,分別接觸各受力部以帶動各連接部以及各彈性球移動。老人或病患平躺於複數彈性球上,施力機構接觸受力部帶動連接部以及複數彈性球移動,讓老人或病患身體產生按摩的效果而達到防褥瘡的目的。1‧‧‧防褥瘡床組12‧‧‧彈性球14‧‧‧施力機構141‧‧‧凸輪軸141a‧‧‧凸輪142‧‧‧圓軸142a、142b‧‧‧凸出部
