Collapsible partition

A collapsible partition comprising:

• a first body comprising a foldable material, the first body having an inward-facing side and an outward-facing side, the first body having a planar configuration when unfolded;
• a first substrate array comprising a plurality of primary substrates, each primary substrate having a flat geometric shape and being resistant to folding, and each primary substrate coupled to the inward-facing side of the first body;
• a second body comprising a foldable material, the second body having an inward-facing side and an outward-facing side, the second body having a planar configuration when unfolded;
• and
• a second substrate array coupled to the first substrate array and comprising a plurality of secondary substrates, each secondary substrate having a flat geometric shape and being resistant to folding, each secondary substrate coupled to the inward-facing side of the second body;
• wherein the first and second substrate arrays are coupled together in an initial arrangement such that:
• the first substrate array is compressed in a longitudinal dimension and/or in a lateral dimension, with the plurality of primary substrates defining an initially folded state for the first substrate array;
• and
• the second substrate array is uncompressed, with the plurality of secondary substrates defining an unfolded state for the second substrate array.
