The Holtzman Suspensors are hovering devices which utilize the secondary (low-drain) phase of a Holtzman field generator to nullify gravity within certain limits prescribed by relative mass and energy consumption.
The original conceptor of the suspensors was Norma Cenva, while working for Tio Holtzman on Poritrin. She was based on Holtzman's original shield design, but was then heavily modified by herself. The first invention which employed this principle were the glowglobes.
Suspensors are used in chairs, tables, and structures that are too massive to be physically sound, among many other obvious uses.
The grotesquely obese Baron Vladimir Harkonnen utilised suspensor belts and harnesses to buoy his flesh and allow him to walk. Suspensors are also used to generate artificial gravity aboard spaceships.
