New input case for you: We had guests that used it last weekend. They said it felt like a real bed. I was so suprised on how quickly it inflated and deflated. The cord hides away in a handy compartment. It keeps its air pressure. No need to carry around a separate pump. Our dog wanted to adopt it as her own bed. The dog jumped on it and tested it toughness. It passed with flying colors.
Output:
Positive
