Question: What is the pole diameter? I can't find it anywhere.
Document: Very sturdy shelves! I like the wheels too!The sleeves for setting shelf height are a bit &#34;cheap&#34;, but once everything is assembled, there were no issues. If you want to move the shelves up/down on a regular basis you made find it difficult since the shelves fit tightly.
I love these shelfs.
Strong, sturdy shelves that are exactly what I needed. Easily put together by two people. Very satisfied with my purchase.
I love to have everything organized, these shelves can hold anything and everything. It is great to have everything put away on such great shelves.
Easy to put together - sturdy - fits my needs. Yes, I would recommend this product -  Everyone can use extra shelves to store things.
Shelf is very sturdy and attractive. It was a breeze to put together and should last &#34;:forever&#34;. I didn't want to pay this much money but it's generally true that you get what you pay for.
I think I have 4 or 5 of these now. They're just great. Sturdy, roll well, priced well, and I've got them all over the house: basement, garage, art cave. Love them.
Solid well built product. I have 4 of these and they are all heavily loaded and work great. Assembly went pretty easy. Getting the parts to line up exactly correct is an issue. But it works after a little pushing and shoving. Beginners can assemble these.
The packaging was wonderful. It is packaged so nothing gets damaged. My other family members love it, and they said this was the best idea anyone could have come up with to make space and save belongings! I definitely recommend this to anyone who wants to make space, who do not have much time to put anything together, who wants something sturdy, and who wants to protect their belongings from the sweat in the winter!
Nice shelves, sturdy but those plastic sleeves are difficult to deal with and makes placing the shelves a real pain. I also think these are over priced. However, the heavy casters are great and the shelf looks great but I could get the sleeves totally covered on some of the shelves. I put it together by myself and took me about an hour which was mostly fidgeting with those stupid sleeves.
