5. The shelving system of claim 4 wherein:

the second sidewall is adhered to the rear wall glue flap.

6. The shelving system of claim 1 wherein:

the outer structure and the inner structure are made of corrugated board.

7. A two component shelving system comprising an outer structure made from a first blank and an inner structure made from a second blank; wherein

the first blank comprises a plurality of front panels, a first sidewall, a second sidewall, a rear wall, a plurality of shelf front flaps, the front panels are connected to the first sidewall and to the second sidewall along first fold lines; the first sidewall is connected to the rear wall along a second fold line; each shelf front flap is connected to a front panel along a third fold line, each shelf front flap has a rear edge and comprises a die cut tab located between the third fold line and the rear edge, the rear wall defines a plurality of vertically spaced apart rear wall slots; and

the second blank comprises a pair of vertically elongated connecting flaps, a plurality of inner horizontal support panels hingedly connected to the vertically elongated connecting flaps along sixth fold lines, and a plurality of shelf rear flaps, each shelf rear flap comprising a main panel and a shelf tab hingedly connected to the main panel along a seventh fold line, each main panel hingedly connected to a corresponding inner horizontal support panel along a fourth fold line, each main panel defining a slot for receiving the die cut tab from a corresponding shelf front flap, each shelf tab configured to cooperate with a corresponding rear wall slot to lock each rear flap in a horizontal, load bearing position.

8. The shelving system of claim 7 wherein:

the first blank further comprises a vertical glue flap affixed to the rear wall along a fifth fold line.

9. The shelving system of claim 8 wherein:

the first sidewall is adhered to one of the connecting flaps of the inner structure; and

the second sidewall is adhered to the other connecting flap of the inner structure and to the rear wall glue flap.

10. The shelving system of claim 7 wherein:

the first blank and the second blank are each made of corrugated board.

11. A method of assembling a shelving system comprising the steps of:

providing a first blank comprising a plurality of front panels, a first sidewall, a second sidewall, a rear wall, a plurality of shelf front flaps and a vertical glue flap; the plurality of front panels being connected to the first sidewall along a first set of co-linear first fold lines and to the second sidewall along a second set of co-linear fold first lines, the first sidewall being connected to the rear wall along a second fold line; each shelf front flap being connected to a front panel along a third fold line, each shelf front flap comprising a tab; the vertical glue flap being hingedly connected to the rear wall along a fifth fold line; the rear wall defining a plurality of rear wall slots;

providing a second blank comprising a pair of vertically elongated connecting flaps, a plurality of inner horizontal support panels hingedly connected to the vertically elongated connecting flaps along sixth fold lines, and a plurality of shelf rear flaps hingedly connected to the inner horizontal support panels along a fourth fold line; each shelf rear flap comprises a main panel defining a slot for receiving the tab from a corresponding shelf front flap and a rear flap tab hingedly connected to the main panel along a seventh fold line;

adhering one of the vertically elongated connecting flaps of second blank to the first sidewall of the first blank;

folding the first blank along the first fold lines and the second fold line;

adhering the second sidewall to the glue flap;

rotating each shelf rear flap along a fourth fold line until each rear flap tab is inserted into a corresponding rear wall slot; and

rotating each shelf front flap along a third fold line until each front flap tab is inserted into a rear flap slot.
