This set doesn't include couplers to secure the two separate shelving sections vertically. You either have a very unstable 6' unit or two stable 3' units.

The shelf did not ship with the couplers for the vertical supports like is shown in the item pictures. The rack cannot be safely assembled as a 72" tall rack without these

The metal frame was of very low quality , the copressed wood board were extra ordinary poor quality . The corners of each board was broken .They clIm it can bear 4000 pound weight but it seem it could not bear 2000 pound ! Bad experience

I have bought 3 sets of these shelves. Well made and so easy to assemble. Used a rubber mallet to assemble frame then slipped the wooden shelves right into the slots. Great product!

This shelving unit is very poorly made! The shelves are sagging when placing a box of dishes. I did not assemble immediately, or I would have returned. Do not buy!!!

This shelf cannot be stacked as pictured. The shelf coupler part is not included and should not be advertised as a stacked unit. I attempted to buy the coupler separately and Walmart doesn't seem to carry it.

This shelf unit was very easy to assemble and is very sturdy when assembled. Great value for the cost. Only complaint is box was in rough shape when I picked it up, taped together and a couple holes. But everything was there and no product damage.

I purchased 4 assuming they were like my previous racks but these do not come with the couplers like the others. I had to make my own which was terribly inconvenient.

Very sturdy. Easy to construct. Shelving is a little weak and has a tendency to bow, but easy fix with additional support. Would recommend for the price!

Very easy to put together if you have a rubber mallet. I love how customizable the shelf heights are and they are deep enough to actually fit large tubs and other large items.
