Embodiments of portable cones are disclosed herein. One disclosed embodiment, for example, comprises a resilient coil spring having successive coils of decreasing diameter. The resilient coil spring of this embodiment has a generally conical shape in its natural state and is compressible into a compressed state. This embodiment further includes a cone-body cover formed from at least one fabric. The cone-body cover is disposed about an exterior of the resilient coil spring and is pulled substantially taut against the exterior of the resilient coil spring when the coil spring extends towards its natural state. The cone-body cover further comprises a tip region and a lower edge. The portable cone further includes a base to which the lower edge of the cone-body cover is attachable, thereby defining between the base and the cone-body cover a first interior in which the resilient coil spring is housed. The base of this embodiment also defines a second interior in which one or more weights (e.g., disc-shaped weights) are located.
