This six-shelf unit was described as heavy duty. That description is very accurate. The box containing the product was very heavy, which was the first clue. The assembly was very easy, but if you want it to be even easier, have a second person help you line up and slide the shelves over the vertical posts. This is a great product and well worth the price!

These shelves are great! Sturdy, easy to put together and customize - and change as needs change. This is my 5th set of these shelves. They are now lining a full wall of my garage and I have not had any problems with any of them. Was able to put this set together solo, but it is infinitely easier with a second person. I have them all set up with the wheels, but haven't yet used the wheels to move the shelves (haven't had a need to move them) so I can't say how easily they move. I think if I do ever move them, I will take the wheels off all but one of the shelves (leave them on the one covering my circuit breaker panel) because the weight the can handle increases greatly without the wheels. My only issue with the shelves is the shelf liner that comes with it. It tends to move a lot when loading things on the shelves. Once they are "anchored" by items being on the shelves, they stay put, but it can be a pain when initially loading up the shelves.

Overall these were great and worth the money I paid. I ordered 3 and now want more my craft room space in finally getting organized. Each box was extremely heavy and the person who delivered them put them on my porch in the way of my door however, my husband and i struggled to get them in the house and then assembled-def a two person project. The boxes had been handled rough and ultimately resulted in on shelf being bent quite out of shape. Box said they would withstand several hundred pounds so i can't imagine how this got bent even with rough handling. I have pictures but have yet to contact Sam's about this.So overall great deal and glad we didn't have to tote them home from a store-bought these particular ones because the casters came with them.

Very strong and durable. I like the fact that you can either have rollers or stable feet to install these shelves. Very easy to assemble, all you need is a rubber mallet. Having liners for the shelves is an added bonus preventing small items from falling through. Would buy again.

I got these for my company, where we have purchased many different manufactures shelving units, and this one is by far the best unit for the price. It's quality is as good or better than the ones for hundreds of dollars. Love all the standard supply options, like casters, adjustable feet, two short units or one tall unit. Going to get more soon.

Bought this for my garage. Fairly easy to assemble, a girlfriend and I (also female) were able to put it together in an hour or so. It has a nice sturdy feel to it, and it's easy to move when necessary because of the wheels. I'm buying another for the storage shed!

We have had several of these shelves for many years. So when our son moved, he needed something to put in the garage. We like these shelves so much, these were the first shelves we thought of. Very sturdy, holds many pounds and is the perfect length. Will buy again!

We added two more of these shelves. We bought 8 previously. They are great and we've had the other 8 for years. Very sturdy, easy to assemble, and they hold a lot of weight. They are super easy to move around even when fully loaded. And we found they are great when moving too, as we loaded them up, wrapped them in plastic wrap and wheeled them into the moving truck. They went right up the ramp. We recommend them.

I bought this product for my wife's sewing room and she could not be more pleased with all of the shelf space. This is a good addition to her room. She likes the ability of changing the spacing of the shelves to suit her storage needs as needs change. Simply assembled and rolled into place and moved as needed with the furnished heavy duty casters. Excellent Long Term Purchase.

This versatile, truly heavy duty shelving can be configured in a number of ways to accommodate your stuff. I have these units serving in my office, shop and attic. Most of the units are assembled as six foot high, 6 shelf units with wheels. One set is assembled as 2 three foot units with 3 shelves each. Another set is assembled as a 3 foot high, 12 foot wide unit with 2 shelves at each 4 foot section. The center section shelves share uprights with the left and right outer sections. This works well in my attic, in fact 2 more sets have been purchased for that purpose.
