Coghlan’s Airstop Sealant, 0.27-Ounce/ 8 ml, 2 Pack

I was skeptical that my expensive SoundAsleep brand air coil mattress could be rescued. It had developed a few large cracks that leaked around the top of a few coils. I applied several coats of the sealant as directed and let it dry for 24 hours. I reinflated and it has held 100% for 4 weeks of sleeping on it every night. This is a miracle cure. The solvent in the sealant actually bonds to the PVC plastic in your mattress and forms a strong seal. I added a foam topper to my mattress to eliminate abrasion on the surface in order to prevent new leaks from developing. Works great and provides a welcome increase in comfort.
