A vibration isolation platform utilizes a plurality of viscoelastic polymer blocks sandwiched between rigid plinths or boards and stacked on top of one another to provide vibration damping additively per layer of the sandwich. Smaller viscoelastic blocks are positioned between the edges of the plinths and the sidewalls of a framework in which the sandwich is mounted to compensate for lack of shear stress in the larger blocks. The platform is pre-loaded to optimum isolation and locked down at the required compression. Optimum isolation is achieved for any electronic component positioned on the platform up to the design weight limit.
