Naturepedic Organic Cotton 2-Sided Contoured Changing Pad Cover
We got two of these for our baby's two changing stations. One is on a changing table, the other on the floor. It needs a covering so don't forget to buy that too. Very lightweight, there's absolutely no nasty smell as you get it out of the box, you can use it right away.
Babies spend a lot of time on these changing pads so going organic is a good idea ;-) stay away from toxic outgassing!
