The Vibrapod Cones work very well with the points facing up. The addition of Vibrapods below the cones can help, but the results are variable. I use CD "coasters" between the base of the cones (or the Vibrapods) and the surface to provide the ability to adjust for level.
Make sure to use paper between any of the Vibrapod products and the surface against which they rest since the black material can interact with surface finishes.
