Underside - blue foam padding. You can see in my photos that when I poke lightly with my fingernail it leaves an imprint. I'm not sure how it's supposed to hold up. Also, as seen in the photo, the seams are so messy and bunched up. You can see the glue seeping through, the seams are uneven, the threads are dangling
