These are the best shelves that anyone could ever hope for. They were very easy to put together, they are sturdy, high quality, and well made. They also hold a lot of weight, are adjustable to fit items of any height, they come in various widths so that we can arrange our storage area with a mix of sizes that match, and the black anthracite performs very well in our non-temperature controlled space. We will be looking to get more of these once we finish our next storage space. These are true winners!
