A collapsible chafing dish stand includes a rim that holds the chafing dish pan; a first leg formed into a first geometric shape having two ends each pivotally coupled to the rim; a second leg similarly formed with two ends each pivotally coupled to the rim; a first cross bar and a second cross bar each formed into a select geometric shape, and pivotally coupled to the first leg and the second leg, respectively; and a hook to releasably couple the first cross bar to the second cross bar to secure the first and second legs in a support position. The improved configuration permits manufacture of a stand with fewer wire bends, simplified hinges and hook, simplified coupling of cross bars, and simplified geometric shapes, all of which combine to minimize material usage, and be more economically producible in a highly competitive marketplace, while retaining structural integrity.
