As you can see from the photos I ordered these shelves for my kitchen as I don't have a suitable pantry at the moment. These shelves have plenty of space and far exceeded my expectations for durability and build quality. If you use wheels, they roll surprisingly well under load as the rolls they provide match the strength of the rest of the unit. How they make a device with such characteristics for $50 I don't understand. My only criticism of these shelves is that the wires are a little far apart for small items. If you plan to use them like I did, I'd recommend buying insoles like these: Comes with two-piece struts that assemble with a nipple in between. Once compiled, these messages become quite long and unwieldy. I suggest putting them together a little differently than the instructions say. Attempting to assemble shelving with posts together or with wheels is frustrating at first, especially if you are assembling them by yourself. Do not assemble the frames and do not mount the wheels beforehand! If you have a desk to work with, open the box fully and leave it on the desk as a desk protector. Starting with 4 bottom posts, place the plastic wedges where you want the bottom shelf and make sure the ribs in the wedges are in the same slot on all legs. Place the bottom shelf on the table you are working on with one long side of the shelf hanging over the edge so you can slide the posts through the shelf without trying to hold it down. Once those two legs are in place, flip the shelf over and install the other two posts. Then place the shelf fully on the table and place the next set of wedges on the racks in the center of the unit. Now lower the next shelf down over the posts. The presence of two locked shelves gives the unit the stability needed to facilitate assembly. When you put the wheels on the block, place it on its back while it's on the table, remove the leveling feet and install the casters. Remember that the set of cardboard casters has wheels that lock. Now lay the block on the ground and continue the building process by attaching the top of the posts and then adding the last 3 shelves. Assembling this way is very easy and takes less than 15 minutes per unit.
