A foldable rocking chair frame includes a left side stand and a right side stand. Each stand includes a rocking structure and a plurality of supports interconnected and foldable into each other. The rocking structure includes an arched member, a slider, and one or more links. When the frame is unfolded, the arched member has an end portion disposed at the rear side of the frame and extends from the rear side of the frame toward the front side of the frame. The slider is disposed at the arched member and slidable along the arched member. Each of the one or more links is pivotally connected to the arched member and a support in the plurality of supports. The left and right side stands are connected by a connecting assembly that allows the left and right side stands to fold into each other.

A modular furniture assembly includes: a base member having a frame assembly, a transverse member having a frame assembly, a foot configured to contact a support surface, and a mounting platform having a plurality of apertures therethrough. The mounting platform is configured to be mounted on the base member frame assembly and the transverse member frame assembly, thereby connecting the frame assemblies. The foot is selectively mounted on the mounting platform, such that the foot is configured to contact the support surface when the modular furniture assembly is in an upright configuration. The mounting platform connects the base and transverse member frame assemblies together and also acts as a platform for receiving a variety of different types of feet.

A rebounding device includes a front member, a rear member, and a spring mechanism positioned between the front member and the rear member for allowing the front member and rear member to move toward and away from one another.
