The metal Table Nest, which provides air flow beneath the EGG, is now an optional component for all Big Green Egg tables. The Table Nest is also useful for custom tables and outdoor kitchens. CAUTION: The metal Table Nest must be used in conjunction with a table, custom island or built-in surround. Not for use as a free-standing support for your EGG. Do not place EGG directly on wood or combustible surface!
