An overhead storage platform supported by vertical members that includes slotted support beams supporting the platform deck. The vertical support members are affixed to a ceiling or other overhead structure on one end and to the slotted support beams on the other end with a cradle clamp, where they are adapted to be adjustably moved and affixed within a slot channel in the slotted support beams. The vertical support members can be adjustable in length as well. These two adjustment dimensions allow more adaptability to affixing the platform to overhead supports of varying configurations. Multiple platforms may be abutted to provide a larger and substantially continuous platform deck.
