I bought these shelves for use in my business. Love them! Easy to assemble and very sturdy! I have a heavy piece of equipment on one of the shelves and this unit holds it stable no problem. I plan to purchase more very soon. The casters are great - I can move the shelves easily to get behind them if necessary. I recommend the 48". It's not as big as you think and it gives you lots of shelf space.

I decided to buy this for additional long term food storage. It took some time to put together by myself but I finally got it done. If I had measured where to put the first set of clips instead of eyeballing them it would have been quicker. I would definitely buy another one if needed.

My husband and I purchased this and put it together a few days ago. Both of us are somewhat handy but for some reason we always take forever to put stuff together. This takes no handiness whatsoever and we had it together in 15 minutes! Now all of our bottled water, toilet paper, diapers, etc. are stored in our basement out of site. Great purchase. I will definitely buy another one if we need similar storage in the future.

I bought this shelving unit to organize a 5x5 storage locker. Assembly took about 20-25 minutes. The only tool you need is a rubber mallet to get the shelves nice and tight. Read the fine print: the max weight capacity does not apply if you use the wheels. I opted for the leveling feet and the unit feels strong.

These are EXCELLENT storage - don't waste your time with plastic shelving, spend the extra $20ish bucks for this. Easy to move around when needed, holds a lot and we use "S" hooks to increase storage of other misc items. We recently purchased 4 more to add to the 2 we aleady had - 2 in the garage and 4 in the basement additional storage.

I have several of these units in my garage and I love how sturdy they are. My first units were similar, but of lower quality. Seville makes excellent quality units that go together easily. You can set them up yourself or very quickly as a two person job. One thing to keep in mind, for maximum weight capacity, you do not use the wheels which make the units less stable and you do not want to tip one over with 600 lbs per shelf loaded. The only question I had was if it was worth $13 to have the unit delivered versus picking it up at Sams. Since Dad had the truck, I got it shipped right to the front door. I expect these units will last 20+ years. I would have given the unit a 5 star value rating, except they used to only cost $69.99 at Sams.

Glad I had it shipped to my house because this thing is big and heavy and I would never have been able to buy it from the store. The shipping was also inexpensive for the weight and I got 2 to set up one in garage and in my computer room. 6 shelves allowed a lot of stuff to be stored.

Be warned, there are round, black plastic discs, some broken, loose in the box. No indication of what they are. Not listed in the parts list. Called Sevillle and had to leave phone number. Never received a return call. The shelf went together fine and still have these parts left over. The only thing I can figure is that they are used in the manufacturing and the factory workers just dumped them in the box. The first box was delivered by FedEX with the bottom flap opened and some of these fell out and a few were broken. I had Sam's send it back and they shipped another one in less than a week. This one also had the discs in it, some broken. Again I thought I had broken parts. I checked the parts list and there was no listing for these and the shelf went together perfectly. All the fustration could have been avoided if they were not in the box, something was mentioned on the instructions or Seville had answered or even returned my call.

I had purchased the same brand rack online and I had seen this one the last time that I went to Sam's. This is actually a heavy duty rack, and even though it looks like the one I purchased online it is much heavier. It did cost a few dollars more but was well worth it.

I purchased 2 of these to replace 2 that I had bought the day before and returned. These shelving units are excellent. They are very heavy duty and easy to assemble. I put them together myself in less than an hour for both units. I wouldn't hesitate to purchase more, if and when I need them!!
