Gallery trays have a raised outer edge that helps hold items on the tray in place. Generally the edge is between an inch to three inches tall. They are ideal for waiting rooms, lobbies or as a coffee-table or side-table tray. Among the styles available are leather-like, silver, stainless steel and nickel-lated trays. Before you decide on a gallery tray, make sure it is appropriate for your needs. If your tray will be placed in a lobby or waiting area, you may want to go with a more economical tray that is easily replaceable in case of theft. Faux leather trays have a natural look and are a great alternative to metal. If you will use your tray in a catering event or in an up-scale lobby, restaurant or home, consider an ornamental metal tray. Gallery trays with gadroon borders - decorative, elaborate border designs, are ideal for weddings, lavish lobbies and casinos. Silver- and nickel-plated decorative trays are more expensive than the stainless steel models but provide a beautiful shine. Keep them regularly polished to maintain the shine.
