Repair kits come with some mattresses and can also be purchased wherever air mattresses are sold. Bike tire patch kits also work well for repairing air mattresses. Find them at bike and general stores.

Other strong glues, such as super glue, contact cement, or epoxy, may also work. You can also find glue that is specifically designed for surfaces such as air mattresses, pool floats, or whitewater rafts. This glue can be found where these items are sold.
