An activity toy or stacker having two or more stackable components that can be assembled into multiple configurations. Surface engagement features retain the stackable components in a self-supporting assembly without an internal frame or support pole, and self-align the stackable components as they are assembled. The surface engagement features of the components are universally interengagable to allow the components to nest with one another in various assembly configurations and orientations.
