Q: This bed was purchased as a spare bed for short time visitors as we are limited in space in our Park Model RV. We needed someting that didn't take up much room to store and yet was comfortable enough so that as person could get a decent nights sleep on it. After reading all the reviews I could find, I deduced that some of these beds were faulty (like all things) and that they tended to deflate overnight, but, that most were fine. Our bed has met all of our expectations and is fine, comfortable and holds the air. I would highly recommend this product!!
