Body support member with lattice structure

A body support structure comprising:

• a field array comprising a plurality of spaced apart support members arranged in a plurality of rows and a plurality of columns, wherein each of the rows has (n1) support members, and wherein each of the columns has (n2) support members, wherein the outermost periphery of the field array comprises (n3) support members, wherein n3=2*n1+(2*(n2−2)), wherein at least one of the rows has a first width and at least another one of the rows has a second width, wherein the first and second widths are different, wherein at least one of the columns has a first length and at least another one of the columns has a second length, wherein the first and second lengths are different;
• a perimeter array defining a closed ring surrounding and connected to the field array, wherein the perimeter array comprises first and second rows of spaced apart support members connected to opposite outermost end rows of the field array, and first and second columns connected to opposite outermost end columns of the field array, wherein the first and second rows and first and second columns of the perimeter array have (n4) support members, wherein n4=(2*n2)+(2*n1);
• and
• wherein the support members in the field array and perimeter array are connected.

A body support structure comprising:

• a plurality of spaced apart support members defining opposite first and second surfaces, wherein adjacent support members define openings between sides of the adjacent support members;
• a plurality of spaced apart base members defining opposite first and second surfaces, wherein the first surfaces of the base members face toward and are spaced apart from the second surfaces of the support members such that the plurality of support members and the plurality of base members define a space therebetween, wherein each of the base members underlies at least portions of the openings defined by at least two adjacent support members, and wherein adjacent base members define openings between sides of the adjacent base members;
• and
• a plurality of connector legs extending across the space, connecting each base member with the at least four adjacent support members, and connecting each support member with at least four adjacent base members, at least some of the connector legs have a different length than other connectors legs, wherein the spaces between at least some of the connected support members and base members are different than the spaces between other connected support members and base members.
