We designed and implemented the kneeling stool to perform CPR with the kneeling posture for a patient on a bed. The frame is constructed of an aluminum alloy. The size is 570 mm (width) x 598 mm (depth) x 600 mm (height). The weight is 9.3 kg, which is easily moved as needed. For easy rotation between rescuers, a step plate was inserted. To prevent pain to the knees of the kneeling CC performer, a 40mmthick sponge cushion was placed on the top plate and fixed to the frame.
