Anatomically conformable foam support pad

A convoluted foam pad for supporting a human body on a bed, comprising:

• a general support area;
• a shoulder support area;
• and
• a tail support area, each of said areas comprising adjacent rows of peaks having flat tops and generally rectangular cross sections, said peaks in each row being separated by valleys and said peaks in adjacent rows being staggered, said valleys in said general support area having a greater average valley thickness than the average valley thickness in said shoulder support area and a greater average valley thickness than the average valley thickness in said tail support area, said peaks and said valleys forming a checkerboard pattern wherein the corners of said peaks in adjacent rows, are connected by webbing.

An elongate convoluted foam mattress having a pair of opposing ends and a pair of longitudinally extending sides, comprising:

• a shoulder support area for supporting the shoulder portion of a body formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley;
• a tail support area for supporting the tail portion of said body formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley;
• a general support area surrounding said shoulder support area and said tail support area formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley, and wherein each of said peaks has a substantially uniform peak thickness and the average valley thickness of said valleys in said shoulder support area and the average valley thickness of said valleys in said tail support area are less than the average valley thickness of said valleys in said general support area;
• and
• a pair of rails extending longitudinally along said sides of said mattress.

A critical care convoluted foam mattress overlay, comprising:

• a shoulder support area for supporting the shoulder portion of a body formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley;
• a tail support area for supporting the tail portion of said body formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley;
• and
• a general support area surrounding said shoulder support area and said tail support area formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley, and wherein each of said peaks has a substantially uniform peak thickness and the average valley thickness of said valleys in said shoulder support area and the average valley thickness of said valleys in said tail support area are less than the average valley thickness of said valleys in said general support area, and said peaks have a peak thickness of between three and five inches.
