Abstract
A support cushion including a first underlying layer made from a flexible foam, at least one side of the first underlying layer being configured with a non-plane surface. The support cushion also includes a second underlying layer made from a flexible foam, at least one side of the second underlying layer being configured with a non-plane surface. The second underlying layer is placed in abutment with the first underlying layer. The support cushion further includes an overlying layer placed in abutment with the second underlying layer, the overlying layer being made from a visco-elastic foam.
Claims36
A support cushion comprising:
- a first underlying layer made from a flexible foam, at least one side of the first underlying layer being configured with a non-plane surface;
- a second underlying layer made from a flexible foam, at least one side of the second underlying layer being configured with a non-plane surface, the second underlying layer being placed in abutment with the first underlying layer;
- and
- an overlying layer placed in abutment with the second underlying layer, the overlying layer being made from a visco-elastic foam;
- wherein the side of the first underlying layer configured with the non-plane surface is placed in abutment with a side of the second underlying layer configured with a plane surface.
A support cushion comprising:
- a first underlying layer made from a flexible foam, at least one side of the first underlying layer being configured with a non-plane surface;
- a second underlying layer made from a flexible foam, at least one side of the second underlying layer being configured with a non-plane surface, the second underlying layer being placed in abutment with the first underlying layer;
- and
- an overlying layer placed in abutment with the second underlying layer, the overlying layer being made from a visco-elastic foam;
- wherein the non-plane surface of at least one of the first and second underlying layers includes truncated cones.
A support cushion comprising:
- a first underlying layer made from a flexible foam, at least one side of the first underlying layer being configured with a non-plane surface;
- a second underlying layer made from a flexible foam, at least one side of the second underlying layer being configured with a non-plane surface, the second underlying layer being placed in abutment with the first underlying layer;
- an overlying layer placed in abutment with the second underlying layer, the overlying layer being made from a visco-elastic foam;
- and
- a top layer placed in abutment with the overlying layer, wherein the top layer is made from a visco-elastic foam.
