    Abstract: A rectangular shelf has a large circular hole therein. A round shelf insert being of about the same thickness as the shelf. The insert has a flange thereon and the insert is placed within the hole with the flange resting on the rectangular shelf. The bottom of the round shelf has a plurality of finger catches mounted equally spaced around the circumference. A large fixed catch is mounted on the rectangular shelf approximate to the hole. In order to turn the round shelf, several fingers are placed on one of the finger catches and the thumb is placed on the fixed catch on the shelf. By squeezing the hand together, the round shelf will rotate within the hole therein or one could reach under the shelf and grab two of the finger catches on opposite sides and then turn the shelf. This will allow the round shelf to rotate and bring to the front items of interest. Small items can still be located on the nonmoving part of the shelf.
