Waterproof Mattress Protector works fantastically well.It's made from terry towelling and has a waterproof backing. It's super soft to the touch and is much better than the traditional plastic waterproof sheets as it doesn't make the rustling/crackling sound with movement, not to mention it's much more comfortable to sleep on than plastic.When wet, the liquid tends to spread, but it doesn't go through to the mattress, which is the aim of this product.This is working really well in my granddaughter's Moses basket, keeping the mattress clean and fresh. It's machine washable and dries really quickly. We're very happy with it.
