A novel, safer crib structure is provided herein. This invention provides a crib in which the mattress can be selectively supported at two different heights with respect to the sides of the crib.

To change the height of the mattress, the drop side front wall is slidably removed, the sheet of plywood is slid out of one groove and slid into another groove, and the dropside front wall is again slidably secured to the end gables. In a preferred embodiment, a single groove is used to retain the mattress support, but the end gables are affixed to the back wall in such way that one gable is higher than the other gable. Wheels or castors are provided under the shorter gable to provide a level orientation.
