The zCush Baby Nap Mats are soft, flexible, and lightweight. They're a little wider, a little longer, and a little firmer. But the biggest difference is the removable pocket cover with just the right amount of inner lining to maximize baby's comfort. And the cover, along with the mat itself, can be easily washed because let's face it, newborns can get things pretty dirty pretty fast! And the variety of pocket covers lets you choose the right cover for the right occasion.
