Support liners and arrangements including the same

A support liner comprising:

• a compressible base having a base surface;
• a plurality substantially parallel rows of adjacent alternating first compressible protrusions and second compressible protrusions protruding in a direction away from the compressible base;
• said first compressible protrusions each having a first longitudinal dimension and a first transverse dimension substantially perpendicular with respect to the first longitudinal dimension, the first longitudinal dimension being greater than the first transverse dimension;
• said second compressible protrusions each having a second longitudinal dimension and a second transverse dimension substantially perpendicular with respect to the second longitudinal dimension, wherein the second longitudinal dimension is substantially parallel to the first transverse dimension;
• wherein bases of adjacent first compressible protrusions and second compressible protrusions in a row are interconnected with the compressible base such that the compressible base forms a common base portion for the first compressible protrusions and the second compressible protrusions;
• and
• wherein the plurality of substantially parallel adjacent rows are staggered such that the second longitudinal dimension in one row is not coincident with another second longitudinal dimension in an adjacent row.
