The Padding is FOAM not air.
I was thrown by the "Pad" portion in the title. This really should be called a Mat or Mattress since the "pad's" I'm familiar with are light. Also, the air nozzles cause you to think it's inflatable. This is NOT inflatable. If you blow air into it, it does not become rigid, it balloons like a trash bag.
The padding is internal foam. NOT air.
In all fairness, the ad doesn't claim otherwise. But I really can't find a good use for this thing. If only you could inflate it, then the additional air cushion I believe would make it worth it. But the foam itself feels little more than you are lying on a thick knitted sweater.
