I purchased an Intex queen air mattress from walmart, It began leaking air from a side seam. I tried all the repair instructions from the Intex customer support, nothing worked! Friends told me to try the Ozark airstop vinal repair kit. WORKED PERFECT !!! Applied it as instructed, no leaking at all. however the Intex airmattress kept springing leaks all along that same seam, 6 in all over 2 months, the Ozark airstoped fixed them all. Even though the Ozark airstop will fix leaks in an Intex air mattress , don't buy one!
