Query: very poor quality

We have guests almost every weekend, so we have need for both single and double inflatable beds. We have purchased at least six single and three double Aerobeds over the last few years. Every one of them (except the last, which is only 3 months old) has developed slow leaks which cannot be found, so cannot be repaired. A guest goes to sleep on a fully inflated mattress, and wakes up in the middle of the night on a hard, or carpeted, floor! The product clearly has a design flaw. They know about it, but can't or won't remedy the problem. STAY AWAY FROM THIS PRODUCT! (We are not sure how we will accommodate our guests in the future, but it's just too expensive to keep buying Aerobeds.)
