A bearing assembly is disclosed, which comprises at least two slidable fasteners interengaged with at least two bearing pieces such that the slidable fasteners have substantially unrestricted biaxial motion relative to one another. The bearing pieces are comprised of self-closable fastener film comprising a base sheet and a multiplicity of ribs projecting from the base sheet, wherein the flat side of the first bearing piece is attached to the flat side of the second bearing piece such that the ribs of the first bearing piece are not parallel relative to the ribs of the second bearing piece.
