The utility model discloses an elastic seat, and relates to the technical field of elastic seats, and the elastic seat comprises an elastic base and a seat body. Wherein the elastic base comprises a base body and an elastic structure, the elastic structure is arranged between the base body and the chair body, and the elastic structure is used for deforming when the chair body bears pressure; the elastic base further comprises an elastic limiting piece, the elastic limiting piece is arranged on the base body and located below the elastic structure, a limiting point position is arranged at the end, away from the elastic limiting piece, of the bottom of the chair body, and the distance between the bottom of the chair body and the base body is gradually reduced in the direction close to the limiting point position. According to the elastic seat, on the basis of ensuring that the elastic base has supporting elasticity, corresponding safety limiting structures are respectively arranged aiming at the back leaning and forward leaning actions of the seat body, the seat body is prevented from excessively leaning back and leaning forward, and the back leaning and forward leaning safety of the seat body is ensured, so that the elastic seat not only can meet the comfortable shaking experience of a user, but also can ensure the comfort of the user. And the safety in the shaking process can be ensured.
