Coil spring containing mattress and method

A mattress comprising:

• a coil spring comprising first and second major opposed surfaces;
• at least one first foam pad at least partially overlaying the first major surface;
• the first foam pad comprising open celled foam material capable of compression in response to the application pressure and expansion upon the relief of pressure;
• a container comprised of a flexible material which contains and seals the coil spring and first foam pad within the container, the container comprising plural sheets of flexible material that are RF welded to form a seal to seal the coil spring and first foam pad within the container;
• a valve coupled to the container and selectively operable to permit the ingress of air into the container to expand the mattress from a compressed condition;
• and
• wherein the coil spring comprises opposed sides extending between the first and second major surfaces and opposed ends extending between the first and second major surfaces, the mattress comprising a first support comprised of open celled foam and extending at least partially along the sides and ends of the coil spring and separating the seal from the coil spring.

A mattress comprising:

• a coil spring comprising first and second major opposed surfaces, first and second side edges, and first and second end edges;
• a first support comprising open celled foam material that at least partially surrounds the first and second side edges and first and second end edges;
• at least one first pad at least partially overlaying the first major surface, the first pad comprising open celled foam material capable of compression in response to pressure and expansion upon the relief of pressure;
• a container comprised of polymer material which contains and seals the coil spring, the first support and first pad within the container, the polymer material being RF welded to provide a seam that is spaced from the coil sprint by the first support, the seam being positioned at an elevation that is above one of the first and second major opposed surfaces and below the other of the first and second opposed major surfaces when the mattress is horizontal;
• a valve coupled to the container and selectively operable to permit the ingress and egress of air into and out of the container to expand the mattress from a compressed condition;
• the first pad having a cross-sectional area which is greater than the cross-sectional area of the first major surface, the first pad ranging in thickness from three-fourth inch to one and one-fourth inch, wherein the first pad is comprised of a material which compresses to twenty-five percent of its uncompressed thickness when subjected to a force in the range of from thirty-three to forty-three pounds per square inch;
• and
• the mattress further comprising at least one first intermediate layer disposed at least partially between the first foam pad and the first major surface and at least one second intermediate layer disposed at least partially overlying second major surface.

A mattress comprising:

• a coil spring having first and second opposed major surfaces, opposed sides and opposed ends;
• a first compressible support comprised of open celled foam material at least partially surrounding the sides and ends of the coil spring;
• a compressible pad overlaying the first major surface of the coil spring;
• a sealed casing containing the coil spring, first compressible support and compressible pad, the sealed casing being RF welded to provide a seam in the casing that is spaced from the coil spring by the first support, the seam extending about the entire perimeter of the mattress at an elevation that is between the elevation of the first and second major surfaces when the mattress is horizontal;
• and
• a valve operable to selectively allow air to flow into the casing to expand the mattress from a compressed condition.
