A novel shelf configuration comprises a plurality of juxtaposed shelf units. Each shelf unit has a straight or arc configuration. The shelf unit has a guiding track thereof facilitating a easy extension of the shelf unit to constitute a shelf. Besides, a T slot is disposed at the front end of shelf unit and a positioning tab is disposed at the rear end of the shelf unit. By engaging of a T slot and a positioning tab of an adjacent shelf unit, two adjacent shelf units can be firmly engaged. While the shelf is not in use, the positioning tab can be released from the T slot by a retaining tab which release the positioning tab. By this arrangement, a combined shelf unit can be released one by one providing a convenient utilization and storage.
