A vibration-control platform that, in some embodiments, includes a bottom plate having three or more wells. The wells receive a plurality of vibration-control elements, which are used to isolate a supported object from vibrations. In some embodiments, the vibration-control elements are rubber balls. The presence of the wells facilitates placement of the vibration-control elements under a top platform or directly under an object, especially when the object is located in a tight space, such as in a component rack, or when the object has a non-uniform weight distribution.
