Very sturdy. Don't like the shelf inserts. They don't support heavy things on the shelves. I had to place cardboard underneath to keep my racks from pushing in the shelving layer. I gave it 5 because it is very sturdy. But you will need to people to build. Very confusing instructions.

Lots to like about this shelving unit. It is sturdy and very easy to assemble. The wheel option was the reason we bought this model. We bought 2 of these, and 1 of the boxes came with some damaged shelves which were replaced with an email and picture to customer support. It would have been very inconvenient to return the item after the box was opened. We are buying more of these and highly recommend them.

Great shelving unit! It was easy to assemble, feels very sturdy, and the adjustable shelves make it versatile for different storage needs. The shelf liners are a nice bonus, and the overall quality is excellent for the price. Highly recommend!

One of the shelve's/tier's post holes is bent in an oval shape, so the shelving unit cannot be assembled. The poles are circular, and all the other post holes are curricular, so the oval shaped hole will not slide on to the post.

Great rolling shelves. Using them in my basement. Just make sure you check them out for damage to the box. I've gotten some that were bent. Hand pick them at the store and you'll be fine. If they look like they've been dropped, get another box.

This is the sixth one we have purchased over the past several years from Sam’s. These shelves are very well made, durable and easy to assemble. We would highly recommend this shelving unit!

Really excellent storage product. Have 3 of these now and they are easy to put together and solid.The wheels make them perfect so I can move them to clean under or whatever. Storage makes life better!

I have these racks all over my house, both inside where people can see them, and in my garage. They are insanely strong and I love that they are on wheels because they can be easily moved around. You don't have to go crazy trying to find a spot where they need to live permanently. If you do happen to overload the shelves and need new wheels you can contact Seville and order exactly the right wheels for your shelves. (I won't tell you how I know that.) I have assembled so many sets of these that I no longer have to look at the directions. 14/10 would recommend.

Very sturdy and spacious, super easy to put together, and holds more stuff than you think it would! We moved our entire bulk pantry to this thing to organize before the holidays and there’s still space to put more stuff. From what I saw when I made my brother build it for me, the shelf heights may be adjustable? Tip: bring someone to help you load it into the cart/your car, this thing is HEAVY!

This is a GREAT BUY for a GREAT Shelving unit! This is our third one. Our pantry keeps growing so we keep adding more shelves! So easy to assemble too! Only took about 20 minutes and it was up and ready to stock. Buy one, or a couple! You won’t be sorry!
