ABSTRACT:
A vibrating matress containing a plurality of independently controlled vibrating units positioned within the mattress in a manner, so as to impart a vibrating resonanace along the length of the mattress for the comfort of a person reclining upon the mattress. Each vibrating unit is comprised of a motor and a shaft to which is attached an adjustable eccentric weight that imparts vibrations when in operation. The location of the vibrating units can be changed within the resilient mattress layers, so as to conform to the physical requirements of the individual reclining on the mattress. Battery operated, individual switches with variable resistors control the frequency of each vibrating unit. Operation of the vibrating units may thus impart the desired level of resonance to slowly and quietly lull an individual to sleep.
