<p>WOOD DESK TOP The specification discloses a desk top in which a prestressing bar having a convex upper surface is located within a groove in the bottom of the desk top. The ends of the bar are biased towards engagement with the upper surface of the groove whereby the desk top itself is biased towards a convex configuration, thereby compensating for forces tending to cause the top to bow downwardly.</p> |
