Very well built, and attractive units for the price . Uses tapered plastic rings to support shelves , which the ring design could be improved. The rings can come loose and fall off until you get the shelves locked in . Once shelves are locked in it’s solid and won’t go anywhere. Use two people if possible to rectify the issue with the plastic rings and it will be easy to assemble. 5 stars for quality and value overall.

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.

We now have 5 (yes, 5!) of these. We use some in our garage along a long wall for organizing and they work great. I even have one loaded with a lot of fluid and it's holding without issues. We recently added some to outdoor sheds, but we left the rollers off because we read that they hold something like 5 times more weight without the rollers. They're super easy and fast to assemble with two people, but with enough time and ingenuity, one person could do it.

I bought 3 of these. One was missing the wheels, plastic liners and 1 set of poles. Another was missing plastic liners. Only one was complete. I didnt need the wheels anyway but the liners and pole would have been nice. I had to have my maintenance dept cut a piece of conduit to use as a pole.

Bought this shelving a few weeks ago. Easy to put together. Very sturdy. Love that you can roll them and love that the wheels lock when you have them where you want them. Shelving is adjustable - we wanted the bottom shelf to store coolers and just measured them to fit. We are using the shelves in the garage for storage and it looks very professional and organized. Would certainly buy this again.

I have used these shelves for years. They are very durable and roll easy even with HEAVY load on them. Shelves can be spaced as needed. I ordered 3 more units and the boxes were not secured when shipped. The "glued ends" came apart and parts were scattered in the UPS truck. However, all parts were found and was able to assemble with no problems.

Well made, sturdy and easy to assemble and the plus is that it comes with liners so small items can be placed on shelves without a problem. I made a comparison from many other websites and nothing came close to Sam's pricing. Highly recommended. It does take 2 people to assemble.

These shelves are perfect for our garage. Due to having the wheels, we can fully use a wall that we couldn’t before because we can just wheel the shelf out of the way when we need access to what’s behind it. They are very sturdy and the price is much less than others I have seen. Don’t hesitate to purchase these if you’re in need of shelving.

The MM 6 tier rolling shelves are Awesome!! I bought this unit for my son as a craft beer making accessory! Perfect!!! I have 6 of them for my home canned foods and pantry items. Best to have a helper when putting the shelves together. Well built, shelf liners make cleanups a breeze, I love the (sturdy wheels) mobility for & cleaning!! Make your life easier ♥️ Definitely recommend purchasing!!!

Shelving is extremely well constructed. This will definitely last a lifetime and can be handed down to another member of your family. Assembly works best with two people involved. I purchased two at once. Glad I did. check a few hours later and all were sold out!
