I purchased these same shelves a few years ago, and they are solid and well built. However, I purchased these "same" shelves recently, and noticed that the quality of construction has gone down (plastic support connectors versus metal in older version, and the brackets feel more flimsily fabricated). I even bent a part by lightly tapping it with a rubber mallet. I don't think I can depend on these. Why not just increase the price a little rather than cutting corners with fabrication? Member's Mark products are normally pretty decent, but I am not happy with these shelves.

Metal is not sturdy. Pieces were bent and a couple were unusable. If you are stacking them it becomes unstable. The link pieces for stacking are not long enough for stability like on other muscle racks. I recommend buying another product. I have had muscle racks from Walmart, lowes, and menards and by far this is the worst one.

I started purchasing these shelves almost 10 years ago when they were made by the original manufacturer for Sam's Club. They have changed the way these shelves are made nearly 5 times since then. Originally any shelf could be placed in any location from top to bottom, with strong metal brackets holding the top and bottom sections together. Also, the frame was steel and could hold a combined total of 6,500 pounds of weight or 650 pounds per shelf. The new ones are FAR from this design. Now, to prevent falling, you must place one shelf in the middle, because you are no longer provided with the strong metal brackets, but instead plastic stubs that simply prevent the top and bottom sections from slipping out of place during assembly. Also, with the new lighter fiberglass design, the frame no longer holds 6,500 pounds, but 4,000 pounds. While this is still impressive if you are not planning on holding more than that, the frame now bends easily as you put it together. This was once my go to shelf, as I own about 15 of them in my garage. Sadly, I returned my most recent one and I will not be purchasing any more until the quality is improved. The original shelves were only $70 each and an average adult could stand on a shelf. Now, the shelf can barely hold itself together and is a whopping $90. THIS SHELF IS NOT WORTH THE MONEY ANYMORE.

I can't believe this thing is as highly reviewed as it is; fake reviews? I echo many of the same 1 star reviews on here. The beams are ridiculously thin; every single front, back and cross beam has to be beat in; only 1 in 6 fit the first time, so beams are bent. The rivets are thick and interfere with the shelf laying flat, so half of those have to be wedged in with a screwdriver. Wife is using for clothes, yarn. That is about all I would trust it for. More useful for firewood and scrap metal than storing anything in the garage. Told my wife if she tired of using it, or we moved; I'm selling them or throwing them out. Not putting these things together again. I have at least three other metal shelf designs for reference, that I've moved multiple times, with no issues.

These shelves are extremely wobbly, and flimsy. it took forever to put them together. I've never had shelves so hard to put together before. I was missing one of the plastic inserts for between the section so hopefully I don't have an issue with that. I still haven't gotten the top shelf on yet because every time I try to do it it just slips out of the holes that you put the brace into. I tried to move it and the whole thing just rocks side to side. if this wasn't so heavy for me to take back to the store I would have taken it back to the store. it definitely was not worth the money. I did so much research on shelving, and these got good reviews, but then I see that some people now are saying that the quality has changed on them. very, very disappointed.

I have purchased more than 15 sets of 4' shelving from Sam's Club over the years, and this is the weakest of the bunch! I had ordered 2 sets of Muscle Rack 5 tier shelves that were on sale for $59.99, but somehow someone else's address was used as a "shipping Address" and therefore they were delivered to that address. I have a set of those, but now they are "Out Of Stock", and they are extremely well built. These Members Mark shelves are made similar, but the gauge of the metal in the uprights, as well as the shelf supports are approximately one-half the thickness of the Muscle Rack shelves. Flimsy is the best word that I can use. I picked up 2 sets of the Members Mark shelves, hauled one down 2 flights of stairs to the basement, and ended up keeping it rather than trying to carry it back out. I will be returning the 2nd set. Sam's Club has always provided a decent quality at a fair price, but this set is way too cheaply built for the money. They do go together in an easy manner due to the metal being so thin and is easily deformed, but they do not provide the strength of the others. In defense of Sam's, the same Muscle Rack that I originally ordered are available at other outlets but at a higher price, and that may be why Sam's has discontinued the item. I would recommend them ONLY if you did not need heavy duty shelves.

BUYER BEWARE! SAVE YOUR MONEY AND BUY A BETTER SHELF! Very cheaply made! The metal beams and metal braces that hold each wood shelf in place are made of very thin and flimsy metal and instantly bend or become warped when trying to put together. The side post are more durable and did not bend but without the metal beams and braces are completely useless.

I bought two of these today and trying to put them together. If you hit the short beams using a rubber mallet, with enough force to seat the rivet, it comes out of the metal beam Making that beam useless. So far I have 2 beams that the rivets came out of. I can see why they took the "Members Mark" logo off of these. I seriously doubt this shelf would hold 4000 pounds. They aren't worth the time it took me to drive 60 miles to pick them up. And they surely aren't worth another 60 miles to return them so I will take my lumps and properly dispose of them in the Dumpster.

I purchased one for my garage while it was on sale. Assembly is easy but the unit is very flimsy and the shelves were already bowed straight from the box. Shelves are made of thin plywood coated by plastic, ergo I would be absolutely amazed if it could hold the weight it is claims to be able to handle. Once assembled, it was not sturdy as the metal is thin and the brackets do not stay connected due to a cheap, "tool-free" design. I'm returning it today and will spend more for a product of higher quality, as this won't last.

This is my second one. Got the first one a few years ago. It’s a great unit. Holds a lot. So when I was looking for another unit, was happy this was still available. This May look the same, but it’s a pain to assemble. The rivets will not seat themselves into the slots. I push on them until they click, I pound them with a mallet, but everyone fell out when I went to the next beam or brace. I was very close to returning it to Sam’s Club. Still don’t know why I need 18 plastic protectors, I only used 16. The instructions were almost useless. I’m concerned about moving it to it’s permanent location. I just don’t feel it’s sturdy. I know Sam’s has a liberal return policy, so I’ll save the box. I will return it if it falls apart when I move it ten feet. DO NOT BUY!
