Abstract: A shelf unit includes a back wall having first and second end sections. First and second side walls extend outwardly from and in general perpendicular relation to the end sections of the back wall. Each side wall includes at least one first slot. The back wall and first and second side walls are formed from a first board made of a corrugated material. At least one first shelf formed from a second board made of a corrugated material extends between the first and second side walls. The first shelf has opposing end sections which project through the first slot of each side wall for securing the first shelf to the first and second side walls without the need of associated fasteners. The first slot has the same shape as a cross-sectional shape of the first shelf.
