A shelf assembly includes a frame assembly having a side member, wherein the frame assembly is operable between stowed and extended positions. A rack assembly includes a first rack hingedly coupled to a second rack. The first rack and the second rack are pivotally coupled to the side member of the frame assembly, and the rack assembly is operable between first and second positions. The first rack and the second rack are angled towards a pivot axis defined between the first rack and the second rack when the rack assembly is in the second position. The rack assembly moves from the first position to the second position as the frame assembly moves from the stowed position to the extended position.
