Rectangular folding tables are more common for banquets and business meetings, with a "seminar" version measuring only 18 inches wide. Square designs suffice for home card tables or extra dining space when entertaining guests.
Round folding tables are more elegant for special events such as weddings, allowing an easier flow of communication between guests.
Legs and frames of folding tables are traditionally made of steel, while tops are melamine, seamless plywood, wood laminate, buffed vinyl or molded plastic. Higher-end tables have extra-thick 14-gauge steel leg construction, spring-loaded leg braces and high-impact plastic leg guides to protect flooring.
