I assembled this shelving unit in 2 3-Tier units. The Unit with the Casters is fine. However, there are a couple of issues with the one with the leveling feet. The threading on one of the TOP POLES (B) is longer than then threading on the other 3 TOP Poles (B). This makes one pole a little longer than the other 3. The 4 caps (I) included do not fit in the top of the Bottom Poles (B).The threaded inserts (J) were screwed into the base of the Top Pole (B). I contacted Seville and I was informed I need to assemble it following the instructions and they sent me a Video on how to assemble it. Unfortunately, the video showed how to install it as one piece using the Wheels. I wrote them back and indicated that I bought this item to be used as 2 separate units as indicated in the description. They ended up sending me 4 new poles with caps on them but they are not the same. They asked me if the product I have was made in Taiwan or Vietnam so they can send the correct parts. I told them Vietnam and sent pictures. When I received the replacement poles, they are made in Taiwan so they are not the same as the one I have. I cannot return the item since I no longer have the original box so now I am stuck with this and have the second unit with the leveling feet assembled with one pole longer than than others and no caps on top of the poles. All you can see is the threading.

These shelves are sturdy and easy to put together. Assembly goes very fast with two people. I use these in my storage unit. It keeps my stuff off the ground and makes it super easy to move things around and access my stuff. We also use them in our garage.

I assembled both these shelves my self. The plastic that holds the shelves up must have the correct direction and lined up with the lines on the poles! I put both the shelves together myself with no help and they are easy to move or two wheels have locks. They also came with a kit to tie to the wall for stability! The shelves bottom liner is prefect! The box they came in was extremely heavy though!

Hubby got the 1st shelf put together and I love it so much that I ordered 2 more (for curbside pickup) - picked them up yesterday. This is a nice looking shelf - with liners. Seems to be well built and very sturdy. It was an especially good value at @20.00 off. I can't wait to (try) get organized!!!!!

The clamps are a little tricky and you will need 2 people most likely to assemble. What I did was put my things in plastic tubs and label them and then put them in the right height before I assembled it because it will not be easy to adjust them later. So get your height first. I have had to move several times and this is the way to go. You can also roll them away from the wall for cleaning behind them. I own lots of these and just love them. One and only downside is that you cannot adjust the shelves very easy after assembly. I also wish they made a plastic cover for them. But...you won't be sorry. This by far is the best little organizer there is.

Great product. Greatly increased my shelving capacity in my garage. Gotta admit, though, I have an easier time assembling things with nuts and bolts, than with those plastic do-hickeys. Wish you could explain why the weight limitations go from a total of 6000 lbs without wheels, to 800 lbs with wheels. Seems a bit extreme.

The fit and finish on the last shelf I bought is not the same as the shelf unit I purchased 6 months ago. The item was poorly packaged and pieces were falling out of the packaging before I even started to unbox it. The main support posts were poorly threaded and when put together they had a bow in them, making it difficult to position the shelves. There are sharp edges everywhere the metal was cut and welded, and there was no sign that any deburring took place.

I was a bit skeptical when ordering because shelves of similar sizes and weight ratings seemed to pretty consistently be $130-$150 from other sellers. But these are really good quality and come with useful extras (e.g. anchoring materials, shelf liners) that weren't included with the ither ones we looked at. Arrived quickly and in good shape. Easy to assemble without help.

Very Durable, High Quality Shelving. Very simple to put together. Because of the weight of the box, it's best to open it outside and bring in each shelf instead of lifting the heavy box. Wasn't an issue for me. It took less than an hour to put together. Would definitely buy again!

This thing was so heavy. Hubby had to use a 2-wheel cart to take it downstairs. Once unboxed, we noticed a shelf was bent. I called my local Sam's club where we purchased it from and was told we would need to bring the entire unit back and get a new one. Difficult to get it bundled up to take 45 mins to my Sam's club . We ended up not taking it back and left the bent shelf out as it wouldn't fit over all the poles.
