The seat uses a built-in microphone to hear baby’s cries, then automatically responds, adjusting its various settings until baby is soothed and quiet again. It has eight soothing motions, three speeds and two vibration settings. Parents can save their favorite settings for baby, or they can turn off the cry detection feature altogether, and use it as a traditional swing instead. It also has 15 songs and sounds, and a three-position recline for maximum comfort.
