An adjustable shelf assembly includes an elongated tension-mounted rod, an elongated frame, and at least one shelf attached to the frame. The elongated tension-mounted rod has a first end and a second end and generally extends in a first plane. The elongated frame has a first end attached to the tension-mounted rod and an opposing second end. The frame generally extends in a second plane which is perpendicular to the first plane of the tension-mounted rod. The at least one shelf has a base wall configured to support objects placed thereon. The base wall generally extends in a third plane which is parallel to and spaced apart from the first plane of the tension mounted-rod.
