These shelves are excellent quality, packed very well, and arrived in a timely manner. We have several outbuildings with concrete floors and we are using them for moveable storage. We just received two more for use with grow lights to start plants indoors, for spring planting outdoors. We can roll them outdoors on good days and back in on snowy days. We would gladly recommend them to friends.

I have bought 8 sets of these shelves for business, personal and school use. Every time I assemble them I think that the engineer that designed them is a genius because they go together so easy with no tools and are extremely sturdy yet move easily on the wheels. I bought them for our schools robotics team and they literally wheel supplies all over the school easily on these shelves. I use them at home in my pantry and in my basement storage. I use them at my office for file storage. They are great. The only caution that I have is that when they come the box is VERY heavy. I tried moving the box by myself and threw out my back. Definitely recommend to open the box and move the shelves to your desired location in pieces.

Need two people to put it together and double check alignment of the shelves as it is frustrating doing it by oneself. A rubber mallet is a must to hit the corners to slide down on the shelves' supports. However, being able to place the shelves the distance apart to hold various height containers is a big plus. When put together, the design gives good support to the shelves. It is very sturdy, easy to move, providing easy access to stored items. The finished product is great and worth 5 stars! I deducted a star for the difficulty in putting it together by oneself.

We are using this sturdy, well made shelf system as two 39 inch high, four foot long shelves. We ordered an extra set of casters from the customer service number printed on the instruction sheet. Like the shelves, the casters couldn't have been at a more reasonable cost and were very promptly shipped. Both my husband and I are well past eighty years of age and found the shelves were easy to assemble and move to our garage where we are using them to organize and store tools plus a few boxes of other treasures. Thank you, Sam's!

We've ordered these before and wanted more for garage organization. They are easy to put together and hold a lot of items.

The sturdy and easy to built shelf is not shaky or feels like the shelf’s might collapse. So far stands weight put on it.

These are really good shelving units. But, the shipping is a -100. FedEx delivered 4 shelving units in the last two weeks. I've opened three boxes and two of them had bent shelves. I was able to use one of them but the other is not usable. Like I said, they are excellent units but the shipping is crap. I'm hoping the last box is in good shape. It's very irritating.

The size and sturdiness of the unit is great, however, I only have 1 star bc of all the sharp edges on the rack that caused me to cut my hand. There were alot of random pieces of metal that weren't grinded off. I was also sent a returned unit which clearly wasn't gone through bc parts were rolling around scratching other parts and there was an empty wrapper inside. I returned it and am probably going to try 1 more time in hopes of it being a fluke. The box is extremely heavy so I hope not to have to keep moving it.

These are awesome! I love them! Super sturdy, easy to assemble, easy to dissemble, too, to move or change, ( use a rubber mallet, with gentle hit). I have some in garage, pole barn, basement. You can build them as shown, or, make two 3-shelf each, with wheels on one and rubber feet on other! I have all mine on wheels, they roll so easy and can be parked close together, you pull out the one you need if space is minimum. No more items stacked on floor getting accidentally wet/damp! I love how you can choose how far apart to place each shelf acc to what you’re using it for. Do they last? YES! Do they rust? NO! Is there a con? Well, since I always buy mine on sale, I haven’t found one yet! And the shelf liners are a plus, too! And there’s always 2 extra plastic pieces for pole, too. If you want them covered, there are plastic zip covers you can buy to fit, or, use a queen bed skirt - put it on the back, with the skirt on top and sides. Attach with clothespins. Then add a shower curtain to front, more clothespins! The latter is in my basement for cleaning supplies, towels, bulk t paper, p towel, etc. (I modeled it after an old line cart from my hospital days!) Just get some and enjoy! ( senior gal who can store/move anything, all by myself!)

Check the boxes before you leave the store. I order 3 and had to lug then all the way back to the store for an exchange because a shelf in 2 of the boxes were damaged at the corner piece you slide onto the poles. They were crushed shut. They are great shelves very sturdy. I recommend 2 people to build them as they are heavy and can get precarious with them being so tall.
