Abstract
A high chair has a tray that has a steel (ferromagnetic) core or insert layer sandwiched between durable plastic layers, to be used with children's dishware that has permanent magnets in their bases or bottoms. The insert can be a sheet of seven-gauge steel, with perforations to relieve some of the weight of the metal. The bottoms may incorporate two or more coin-shaped permanent magnets.
