I originally got the Swaddlebees mattress pad to use on our bed to catch nursing leaks, but I ended up using it on the floor as a move-anywhere changing pad. It's super-easy to wash and dry, which is hugely useful if you have a little one who squirms during diaper changes! The size is generous and works great for changes. It would also work as a small picnic blanket, as the waterproof PUL backing will keep any grass moisture from seeping through.
