Hmmm....this shelf is not very difficult to put together as long as you have 2 people work together otherwise it might be very frustrating because the beams keeps popping loose. I also found out that if you put the sheet down after putting each level of beams together it won't fall apart so easily. Overall, with the price I paid it's not too bad. Plus we ended up having 2 individual shelves rather than a tall tall one.

I'm giving 3 stars because the shelves are sturdy, attractive and go together easily. I'm deducted 2 stars because of the corners cut to save a couple pennies in boxing these heavy shelves. The box is 48" long x 18" wide and had 3 heavy 1" plastic straps around the width. They worked great. The bottoms, however, are 2 pieces of med weight cardboard folded over and stapled closed. UPS did a wonderful job keeping the damage to a minimum but w/out reinforcements these boxes are doomed to fail. Great shelves but my advice is pick them up in person. 3 people make assembly a breeze. Put 48" section together and add a couple shelves for stability. Put 36" section together and add top shelf. Set top on bottom with one person on each end. 3rd person adds middle shelf supports and taps them in place with a rubber hammer.

This has been one of our most disappointing purchases ever at Sam's. To put this together you need 2 people. One to hold it down because these racks just don't snap in & stay together, they keep popping out. Getting the 2nd upper vertical rod on is very & very difficult, to keep it all together. We got it finished but it was sweat & tears.... we bought this one since Sam's was out of the black plastic ones which we have & those are great. The only reason we give it 2 stars is because at least it was NOT made in China and in the end it looked OK. Just have a hammer & piece of real wood ready as well for this assembly.

I bough 3 of the deeper 5 shelf version of this and love them, but needed some shallower shelves so I bought these. The other version has a "coupler" that attaches the top portion to the bottom portion and it works well. For some reason this design omits that feature. Instead, the top and bottom are "joined" using one of the brackets for a shelf. The instructions say to "build" to the top portion, sans shelves, and lift and place onto the bottom assembly using the shelf bracket to attach them. Unfortunately the brackets don't fit snugly enough into the rails so the whole thing falls apart. So you have to start again. This is definitely not something that you should try to put together by yourself. In fact, I'd have TWO extra people with you. With some sort of coupler I would give this 5 stars. As is, it only gets 3.

These shelves do what I need. The price is very good. They are a little bit of a bear to put together. THESE ARE NOT COMMERCIAL!!!! 600LB rating is optimistic. I would never put that much for an extended period of time. The wood planks are laminated pressed board about 1/4 inch thick. It might take a load if it was sitting on the supports around the edges. I would not trust that weight in the center. The other two factors making these not suitable for commercial applications is how the top connects to the bottom. It It sits on a 1/16 of an inch ledge and is held together by the center shelf. I feel like like heavy weight up top might cause uprights to slip. The third issue is that the lugs do not lock well. I am comparing these to actual commercial grade storage. These are good for homeowner use. The commercial grade storage like these I do use would cost about $600. I would rate this a 4; if it wasn't for the description of commercial grade. The price is what makes them good.

We have bought many of these over the last few years and been very pleased. This latest version is beyond worthless. As others have said, the rivets are so loose in the holes it's like setting up domino's and holding your breath but nothing you do will allow these to be usable unless you want to duct tape the heck out of it. Waste of time.

Industrial strength?! Maybe in China, but not in the U.S. I've been trying half the morning to assemble this awful thing. I have this exact model that I bought several years ago, and the difference in quality is obvious. The metal is now so thin that when you click one end into place, the other end pops back out. If I can ever get it together, and I'm very careful loading it, it might hold my boxes OK. I had planned on buying a dozen of these when we build our new house, but now I am going to have to rethink that decision.

Bought two of these shelf units along with two others of a smaller size for garage in new house. So far have only received these shelves and not the two smaller ones yet. Opened the boxes to find shelves broken in both boxes. Decided to try and make at least one shelf unit out of the pieces that I had, but as soon as I started trying to put them together, I found the uprights weren't square. So couldn't even assemble one shelf unit out of two boxes! Returned both shelving units to our local Sam's Club and bought Muscle Rack shelves from a well known DIY store.

So far so good, Yes, It is a challenge for one person to put together. But, when together, they seem to have potential. They won't hold an anvil, but fine for storing Christmas stuff. I think they are a bit too tall , I have one completed as one tall and out of reach top shelf, I think I will reconfigure it and the other two as a four and two on the side, and for safety, screw the whole thing to the wall. One final note, if you're alone, Talk to this thing, don't give up and you will think it is worth it when you are done.

They're a nightmare to put together because the connections keep coming loose whenever you move the thing. They come loose even after it's fully built! Just moving the shelves a little makes them come loose. The second set of shelves that goes on top just sits on top of the first set without any strong bracket to keep them there, which leads me to believe they can easily bend and injure me. The vertical supports bend easily. Nothing about it gives me the confidence that it can hold more than maybe 100 pounds each shelf max.
