A controlled pressure and floatation system includes support and flotation units, each comprised by two types of chambers: a main one that contains a liquid substance and a secondary empty chamber; interconnected by a free-flow supply pipe. The main chamber receives the body to be held displacing an amount of liquid substance, in proportion to the weight it receives, towards the secondary chamber, that has no contact with the supported body. The pressures and flotation are controlled by the relative height of the secondary chamber (initial and final pressures), its predetermined shape (sequence of pressures until reaching the resting stage); and the density of the liquid substance. Multi-systems to provide different pressures to different parts of the same body may be created with this basic unit or system.

1. A controlled pressure and flotation system, comprising:a main chamber formed of a flexible, elastic and impermeable material, adapted to be filled with a liquid and then to be hermetically sealed with respect to an ambient environment, in order to act as a support for any body resting on an external surface of said main chamber; at least one secondary chamber, arranged higher than said main chamber yet in communication with said main chamber; and a free flow conduit, made of an impermable, flexible and non-collapsible material, providing said communication between the main chamber and the at least one secondary chamber, permitting free flow of liquid from the flexible main chamber, in response to load placed on said main chamber by said body, and from said secondary chamber back to said main chamber, wherein said secondary chamber has a larger volume than does said main chamber. 2. The controlled pressure and flotation system of claim 1, wherein a respective free flow conduit is provided for each secondary chamber.3. The controlled pressure and flotation system of claim 1, wherein said secondary chamber is adapted to be free of liquid until load is placed on said main chamber and then to receive displaced liquid, said secondary chamber being formed with a shape and height profile corresponding to a desired sequential pattern of firmness or support intended to be provided to said resting body by said main chamber.4. The controlled pressure and flotation system of claim 3, wherein said secondary chamber has a horizontally elongated transversal section to provide a support pattern going from soft to soft.5. The controlled pressure and flotation system of claim 3, wherein said secondary chamber has a vertically elongated transversal section to provide a support pattern going from firm to firm.6. The controlled pressure and flotation system of claim 1, wherein said main chamber is shaped to provide support to the seat and back of a human being.7. The controlled pressure and flotation system of claim 1, wherein said main chamber is shaped to provide support to a human being resting in a prone orientation.8. The controlled pressure and flotation system of claim 1, wherein a lowermost portion of said secondary chamber is always higher than an uppermost portion of said main chamber, thereby assuring that any liquid present flows by gravity from said secondary chamber into said main chamber whenever said main chamber is free of loading.9. The controlled pressure and flotation system of claim 1, further comprising means for reaching and maintaining a predetermined temperature of a liquid inside said system.10. The controlled pressure and flotation system of claim 1, further comprising means for imparting vibration to liquid inside said system, to thereby massage a human body resting on said main chamber.11. The controlled pressure and flotation system of claim 1, wherein said main chamber, in an unloaded state, is completely filled with water.12. The controlled pressure and flotation system of claim 1, wherein said main chamber, in an unloaded state, is completely filled with oil.13. The controlled pressure and flotation system of claim 1, wherein said main chamber, in an unloaded state, is completely filled with a gel.14. A controlled pressure and flotation system comprising:a main chamber formed of a flexible, elastic and impermeable material, adapted to be filled with a liquid and then to be hermetically sealed with respect to an ambient environment, in order to act as a support for any body resting on an external surface of said main chamber; at least one secondary chamber, arranged higher than said main chamber yet in communication with said main chamber wherein said secondary chamber is adapted to be free of liquid until load is placed on said main chamber and then to receive displaced liquid, said secondary chamber being formed with a shape and height profile corresponding to a desired sequential pattern of firmness or support intended to be provided to said resting body by said main chamber; and a free flow conduit, made of an impermeable, flexible and non-collapsible material, providing said communication between the main chamber and the at least one secondary chamber, permitting free flow of liquid from the flexible main chamber, in response to load placed on said main chamber by said body, and from said secondary chamber back to said main chamber, wherein said secondary chamber has an L-shaped transversal section for a support pattern going quickly from soft to firm. 15. A controlled pressure and flotation system comprising:a main chamber formed of a flexible, elastic and impermeable material, adapted to be filled with a liquid and then to be hermetically sealed with respect to an ambient environment, in order to act as a support for any body resting on an external surface of said main chamber; at least one secondary chamber, arranged higher than said main chamber yet in communication with said main chamber wherein said secondary chamber is adapted to be free of liquid until load is placed on said main chamber and then to receive displaced liquid, said secondary chamber being formed with a shape and height profile corresponding to a desired sequential pattern of firmness or support intended to be provided to said resting body by said main chamber; and a free flow conduit, made of an impermeable, flexible and non-collapsible material, providing said communication between the main chamber and the at least one secondary chamber, permitting free flow of liquid from the flexible main chamber, in response to load placed on said main chamber by said body, and from said secondary chamber back to said main chamber, wherein said secondary chamber has a trapezoidal transversal section for a support pattern going gradually from soft to firm.
