Bicast leather (also known as bycast leather or PU leather) is
a synthetic upholstery product consisting of a thick polyurethane
layer applied to a leather or reconstituted leather substrate.
It is commonly found in inexpensive furniture.
Some manufacturers use the bycast treatment to process their
leather, which provides a smooth, shiny finish as well as protection
to the leather.
Because bicast leather is fundamentally a man-made product, some
jurisdictions (such as New Zealand and the United Kingdom) have
ruled that it cannot be marketed as leather.
