A mount for locating a motor assembly within a coil spring assembly. The spring assembly has at least one coil with a helical portion which defines an inner circumference between first and second ends of the helix and a generally planar, circular portion that is attached at an end of the helix. The mount comprises an upper plate dimensioned to overlie the circular portion. The upper plate has a central aperture which opens into a dependent tubular housing. The tubular housing has an exterior circumference less than the inner circumference defined by the helical portion of the spring and an inner circumference dimensioned to receive the motor assembly therein.
