Cariboo Wool Bassinet Mattress Topper

This topper does what it says it's supposed to do, at least according to the Cariboo website."Wool naturally draws moisture away from baby and can hold up to a third of its weight in moisture"That's fine, if you want to wash or air it out every morning. And since it's wool, it needs to be air dried after each washing. I purchased the Cariboo Folding Bassinet, and the mattress that comes with it is good enough for the amount of time the baby is going to spend in it.
