The unit is very sturdy and fairly easy to assemble, take two people to install shelves. The only disappointing thing is one of the shelves was bent and won't fit correctly. I just put it together today and haven't contacted anyone yet about bent shelf.

I bought several of these to finish out my kitchen pantry. Relatively easy to assemble, definitely requires two people. My husband and I had three of them assembled and put into place in about 45 minutes. Very stable, easy to level, love the adjustable shelf aspects. Strong too. I have 3 more for in my garage, not assembled yet.

Arrived damaged, appears that someone dropped it on the edge and some of the holes were no longer circular. I contacted customer service and was told i did not have to return it, and another one would be shipped. Next I received an email indicating I had to return it. Assuming my customer service rep was correct, I ignored the email. Now, I'm being told that he was wrong. I do have to return it. It's half put together (3 shelves were okay), and the box has been thrown away. It is too heavy to pick up, but thankfully Sam's Club will have a shipper to pick it up as it is (no box, half put together) for return. I guess it could have been worse.

These shelves are actually 47 inches wide, 45 inches between the poles if you plan to use storage containers and slightly less than 18 inches deep, with only 15.5 inches between the poles. I have to either return the shelves or get smaller storage totes

I love these shelves. I would say very simple to install...but not something I would want to rearrange the shelves often as they are heavy and easier to adjust with 2 people and a rubber mallet. I own at least 8 of them for my small business and have a few in my garage at home. I've yet to have one break and we put some heavy stuff on it with constant use. built to last!

On average, 1-2 shelves in each box has a won't fit well on all 4 corners. It's because the welding connecting the shelves to the cylindrical sleeves that go around the pole is of spotty quality. The welded material sometimes jets out into where the pole should be - either preventing the shelf from going on the pole, or making one of the corners not fit evenly. In a couple cases, there was a corner with the cylinder not fully closed, making it too loose to hug the connectors. Also, please read the description / packaging carefully​: the allowed load is GREATLY reduced if wheels are used instead of the stationary feet.

I have 5 of these shelves and they're amazing! Adjustable height is a great feature and I often use S hooks and magnets to hang things off the side. I'm using two in my office, one in the kitchen, and two in my storage shed. They hold up great. Being able to roll it makes it much easier to move to clean it or rearrange. It's just a great product and I rec'd it to a lot of friends and family.

This recent purchase of three units is a continuation of a project that now has my total number of units at 14. They each hold a lot of weight and when time comes to sweep the floor I can simply move them, clean up and put them back in their place with ease. I am sure more of these will be acquired as I continue to bring order to all of my things which can easily be seen when placed on these units.

Make sure you check each shelf carefully before attempting to put this together. Three of the 6 shelves had defects- instead of 4 ROUND openings to slide the shelf onto the poles, at least one opening was OVAL vs. ROUND shaped, which made it very difficult to get the shelf to sit level on the poles. I struggled with two of the lesser deformed of the 3 shelves and with the help of a rubber mallet, got them to stay put and level. However, the last shelf had such a deformed oval-shaped opening that it wouldn't sit properly on the poles at all. I contacted Sam's and they worked with me to give me a partial refund so I wouldn't have to return the 100 lb thing!
