Abstract
The present invention discloses a permeable mattress, or permeable pillow, which includes a base (1). Cushioning support (3) are attached to the top of the base in a distributed manner, to support a mesh (4) which supports a person, or person's head. Adjacent to the mesh there may be one or more layers of each, or any, of the following; permeable fabric, permeable foam, permeable fibres or perforated rubber. The mattress may be covered in a layer of permeable fabric (6). Any of the layers may be removably attached to the mattress assembly. In a further embodiment of the invention, beneath the base of the mattress, or integral with the base, there may be provided a spill tray that has a contoured structure, to guide fluids such that they flow under gravity into a collecting bowl.
Claims46
A permeable mattress that is permeable to air and liquids, the permeable mattress including:
- a substantially rigid base, the base incorporating substantially rigid cross members, the base including holes in the areas between the cross members to permit the flow of air and liquids through the base;
- cushioning supports attached to various cross members of the base, the cushioning supports being attached to and supported by the base in a distributed manner;
- a flexible mesh which overlays all of the cushioning supports, the mesh being permeable to air and liquids, the mesh being held in association with each of the cushioning supports by being attached to numerous cushioning supports, the top surface of the mesh also being held away from and above the base such that any point on the top surface of the mesh can move vertically independently of the base, and the mesh being composed of a material that does not absorb water;
- and
- whereby, the permeable mattress provides adequate support to at least one person and the load of a person lying on the mattress is distributed over numerous cushioning supports, and, the mesh and cushioning support interfaces are structured such that air or liquids are riot trapped at the interfaces.
A permeable mattress that is permeable to air and liquids, the permeable mattress including:
- a flexible base, the flexible base being a substantially flexible frame or sheet and incorporating cross members, the flexible base including holes in the areas between the cross members to permit the flow of air and liquids through the base;
- rigid supports attached to various cross members of the flexible base, the rigid supports being attached to and supported by the flexible base in a distributed manner;
- a flexible mesh which overlays all of the rigid supports, the mesh being permeable to air and liquids, and the mesh being held in association with numerous rigid supports, the top surface of the mesh also being held away from and above the flexible base such that any point on the top surface of the mesh can move vertically independently of the general extent of the top surface of the mesh, and the mesh being composed of a material that does not absorb water;
- and
- whereby, the permeable mattress provides adequate support to at least one person and the load of a person lying on the mattress is distributed over numerous rigid supports, and, the mesh and rigid support interfaces are structured such that air or liquids are not trapped at the interfaces.
