I concur with what Chin said. It also prevents tiny pebbles or specs of anything hard from putting stress on a single point of the bottom of your tank.

Imagine the weight of your tank , and a tiny piece of gravel under it somewhere :S

Better safe than sorry with like a 1/2" sheet of foam buffering it.
