Query: This really works well.

I really like this. Both sides are waterproof and wipeable. It packs up really nice. It's pretty big. I feel like this would work well on a picnic. I bought it for couch with puppies. Works well for that too although they love digging at it to make the vinyl noise (they're weird). It's held up well. Only complaint is if you use it on couch, the flaps for the packet it folds into are awfully rigid.
