My son and 10 year old granddaughter planned a week tent camping trip in northern Idaho.  Needless to say, I at 60+ was not looking forward to sleeping on the ground.  I looked around in various stores for an inflatable mattress - the cheap pool mats were non-existent or too small.  REI offerred several great mattresses, but required a dollar investment I wasn't willing to make for what could be a one-time need.  I was thrilled to find these mattresses on Amazon.  The price was within my budget and the reviews were pretty good.  I bought 3 of them and they were delivered as expected.  On first seeing them, I was surprised at the quality giving the cost - not flimsy plastic; they looked sturdy.  I slept comfortably every night of our camping trip. Mine lost a little air after a day or two, but nothing I wouldn't have expected from any air mattress.  I was very pleased with my purchase and recommend them to others.
