Query: Ordered 3... all failed to hold air!

I ordered 3 of these mattresses to use on vacation. I had them shipped directly to our vacation rental. On the first night, two of the three did not hold air through the night. The other failed on the second night. We tested the failed mattresses on the second day as we were out and about and they completely lost air from their own weight by the time we returned. This was not a case of "stretching" as described by one reviewer. If you need a mattress you can depend on, then I would avoid this product. Having been an Amazon customer for many years, this is the first time I've purchased something from the site that did not perform as expected. I am very disappointed.
