Ergonomic arm support

An arm support connectable to an object, comprising:

• (a) a base connectable to said object;
• (b) an armrest for engaging at least a portion of an arm;
• and
• (c) an extension means comprising:
• i) an elongate shroud connected to said armrest;
• and,
• ii) pillow block between said base and said armrest for connection and extension of said armrest relative to said base,
• said elongate shroud being slidable relative to said pillow block, said elongate shroud substantially covering and surrounding said pillow block, said pillow block having a roller bearing means for engaging said elongate shroud for reducing friction between said elongate shroud and said pillow block,
• whereby a wide range of fluid motion is provided for the arm supported by the arm support,
• said pillow block being engaged to said base, said pillow block being vertically adjustable relative to said object,
• whereby said arm support and said shroud are provided with slidable motion relative to said object.
