Query: Ruined by Changing Table

This product ruined by new son's changing table, which would have been converted to his bureau when older. Following the caution I placed it on a mat and was horrified to find that even with the recommended protection layer it still ruined the finish and cracked the wood.The warmer is a great idea and I have enjoyed the comfort it provides. If you purchase this product be sure to by the plastic station caddy that sets it high off the surface. As ugly as it is, it will save your changing table. Frankly, I do not think this product should be sold without it.
