Easy to use and effective against bedwetting, the moisture sensing Dry-Me Bed-Mat Treatment System is specifically designed for children who refuse to wear an alarm. Placed under the bed sheet or inside a pillow case underneath the sleeping child, the alarm sounds when the pad’s sensor strips detect moisture. The 21" x 15.5” bed pad connects to the alarm unit with a convenient 7' cord. Clip the red alarm unit to bed sheet or pillow so child can easily hear it. Choose between 8 loud sounds and vibration, sounds only, or vibration only. To turn off the alarm, simply disconnect and press the reset button.
