A trampoline swingset suspension includes a trampoline frame having at least three legs. A trampoline bed is suspended from the trampoline frame. Springs connect between the trampoline bed and the trampoline frame to provide resilient restoring force for a user. The trampoline enclosure frame includes a plurality of vertical trampoline enclosure frame members. An enclosure net is mounted to the trampoline enclosure frame. A swingset frame is mounted to at least two of the at least three legs of the trampoline frame. A swing seat is suspended from the swingset frame. A spring suspension connects the swingset frame to the trampoline frame. The spring is a coil spring having an upper end bounded by an upper pin and the coil spring has a lower end bounded by a lower pin.

A swing set assistance kit includes a flexible cantilever member such as a helical spring, with its first end attachable to a base which is a plate or a bracket with a first stud. A transverse bar has a second stud at its mid-section and its ends affixed at intermediate points of the lines attaching the swing seat to an overhead beam of the swing set. An alternative embodiment directed to swing seats such as a tire or other arbitrary seat shapes has seat lines attaching the seat to a seat plate that has the second stud for attachment to the flexible member. The flexible cantilever member and its attachment points to the other swinging components alters the effective length of the pendulum of the system, which may be used to alter the natural period of the system, allowing a user to achieve large amplitude, enjoyable swinging more quickly.
