A pull-down shelf for storage of articles has a lower shelf portion that contains a wind-up mechanism, which can be spring powered or motorized, an overhead mounting plate that attaches to ceiling joists or the like, and at least a pair of cables that are wound onto arbors of the wind-up mechanism for suspending the shelf portion from the overhead mounting plate. Scissors-action stabilizers hold the shelf from tipping or swinging. The user pulls the shelf down, and this unwinds the cables and charges the springs. A releasable ratchet wheel keeps the mechanism from turning in the rewind direction. The user can pull or actuate a release handle or button to release the shelf and let the spring rewind the cables to pull the shelf back to its overhead position.
