A method for fabricating a custom anatomical cushion and a device to capture pressure controlled shape is provided. The device comprises, generally, a flexible membrane enclosing floating beads adapted to be completely immersed and freely moving inside a fluid. The device further comprises a mesh adapted to stop the floating beads from going outside of the flexible membrane as a result of a pressure increase or decrease inside the flexible membrane. The device is being fluidly connected to a pressure control system adapted to increase and/or decrease the internal pressure of the flexible membrane and comprises a vibration/leveling system adapted to adjust the fluid level inside the flexible membrane.
