I have read that it is difficult to find sheets and mattress pads for Mika Mickey's bedside table. These mattress pads fit mine perfectly without straying. The width of the sag is less than the length (see photo of the back of the mattress). I could see some kind of elastic to pull it up my back to make sure it really stays in place. But I think that in both cases everything will be fine. Can't comment on absorbency or waterproofing as it hasn't arrived yet so haven't used it. But I washed and dried both skirts and they fit my Mika Mickey perfectly.
