How to fix a leak on an inflatable mattress seam. Applying a large patch
We're patching an air mattress; there's a hole in the seam. To fix this, we need to increase the patch area. http://palatka.net.ua/naduvnye-matras...
A larger patch will transfer the load from the torn part of the mattress to the intact and strong elements of the inflatable shell. The patch will last a long time and be reliable.
