Single bed will no longer pump up What do you do now?

If your single bed no longer inflates, first check the power supply to ensure it's plugged in and functioning. Inspect the air mattress for any visible punctures or leaks, and use soapy water to identify small holes by looking for bubbles. If you find a leak, use an appropriate patch kit to repair it. If the issue persists after these steps, consider contacting the manufacturer for assistance or replacement options.
