A lazy Susan is an addition to a table, which is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable(转盘), which usually moves the food in a circle when pushed by those at table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place as the lazy Susan is turned about.

A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.

Whether the lazy Susan is on a tabletop or within a cabinet, it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan, though it was referred to as a dumb waiter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留声机), which later developed into the lazy Susan.

Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rather than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
