These Ziggy Baby changing pad covers are so soft! I just ordered the matching crib sheets as well! They fit perfect on my large contoured change pad. There is no slot for the safety straps but that is not a problem the straps just go around. These covers also make a perfect bassinet sheet! I put one on my Bugaboo Cameleons bassinet and it works pretty much perfect. My son is a toddler so diaper changes are not messy so I haven't needed to wash them yet, but I think they will just keep getting softer! Check them out on Amazon! They would be a great baby shower gift.
