A method of manufacture may include providing a first platform having a substantially planar first surface and a second platform having a substantially planar second surface substantially parallel to the first surface. The method may further include mechanically coupling the second surface and first surface via a plurality of compression springs allowing movement of the second platform relative to the first platform. Additionally, the method may include mechanically coupling at least one weight sensor to the second platform configured to measure a portion of weight of a load upon the apparatus. Moreover, the method may include communicatively coupling a compression spring control module to at least one compression spring of the plurality of compression springs and the at least one weight sensor configured to tune the at least one compression spring based at least on the portion of weight of the load measured by the at least one weight sensor.
