I need it to be more firm. And to move it to another place I need to deflate it. It is a full size and the left side works fine, I hear the pump and see/feel the results. The pump doesn't make any noise when trying to change the right side. Thanks for your help.

You have a power failure. Check the power adapter with a meter and see if you are getting voltage. If you are getting voltage then check the air hoses for kinks. Let me know what you find.

Thank You for the answer. There are no kinks... got to find out how to use the meter that's in my tool box... BUT, the other side works just fine.

The meter is easy to use. The volt meter just checks to see if there is voltage and how much; you have DC and AC voltage. The AC comes out of the wall at 120 volts; the DC comes out of the power adapter if you have one. Ohms checks continuity and is never used with the power on a circuit as it will burn up meter.
