This is a flat 100% Organic Cotton Mattress Pad for your Baby Bunk Cosleeper. This is very important for soaking up any moisture before it leaks onto the wool pad or mattress. The wool pad is highly recommended as well in order to keep the moisture from getting to the mattress itself. The moisture puddles on top of the wool and the combination of that with the cotton pad keeps the baby dry as well.
