Abstract: An apparatus (1) for the vibration of a cot (2), a cradle, or the like includes a vibration unit (3), which can be applied to the cot (2) by a removable coupling (16); a pair of elastic supports (5), which can be applied to the ends of a pair of respective legs (2?) of the cot (2); and a vibrators (6) located in the vibration unit (3), which are designed to cause the vibration unit (6) to vibrate. The movement caused by the vibrator (6) being transmitted by the vibration unit (3) to the cot (2) and to the pair of elastic supports (5), generating a composite oscillatory movement deriving from the sum of the oscillations of the cot (2) and of the ones transmitted to the elastic supports (5); the apparatus (1) also includes an activator and controller (7, 10) capable of interacting with the vibration unit (6), enabling activation thereof.
