Abstract: A stabilizing device having a first side having a concentric raised wall disposed adjacent to a perimeter. A second side has a concentric recess disposed adjacent to the perimeter. The stabilizing device has a cylindrical boundary wall at the perimeter connecting the first side to the second side. The stabilizing devices are stackable such that when a second stabilizing device is stacked on top of a first stabilizing device, the concentric raised wall disposed on the first side fits snugly into the concentric recess disposed on the second side of the second stabilizing device.
