PROBLEM TO BE SOLVED: To provide play equipment which can be readily moved and safely used even in a room or the like. SOLUTION: The spring play equipment includes a seat portion 10 and a flat base 20 for supporting the seat portion 10 from below through springs. The seat portion 10 is supported by two springs 30 and 30 disposed in a horizontal direction of the seat portion 10 side by side to receive horizontal load on the spring equipment, and the movement of the seat portion 10 is limited into vertical and back and forth directions to restrict rolling and tilting in hopping.
