A support cushion for fast inflation and deflation comprises an air pouch and an air valve located on the air pouch. The air valve includes a valve base, a valve cover, a valve pillar and a locking member. The valve base has at least one air vent leading to the air pouch. The valve cover is coupled on the valve base to form an accommodating trough to accommodate the valve pillar. The valve pillar has a first opening and a second opening communicated with each other. The valve pillar also has a first position relative to the valve base to allow air to pass and a second position to block the airflow. The locking member can receive a turning force to drive the valve pillar to switch between the first and second positions. Operation is simpler and faster switch can be achieved, and leakage of air can be avoided.
