I know these are bookshelves but….

I know these are bookshelves but I used them to redo my son's closet and it worked like a charm. We removed those awful wire racks and placed these instead. They are super sturdy and hold all of his stuff. They only took a few minutes to assemble by myself and then anchored them to the wall. So far they are holding up great and many of my friends have used them as closet storage as well.

Easy to put together and good for the price

I had purchased three, one white, one black and this one in walnut. It wasn't hard to put together but again like others have said the cardboard back panels are cheap/thin or the pins that are supposed to keep it on the back are not good enough. If you are not careful it can pop off (it happened to the white bookcase but not the walnut bookcase luckily). But for the price I will for sure by it again if I decide I need another shelf. I saw another review that used wallpaper to cover up the imperfections of the cardboard back and decided to buy some just in case but just used it to make it look better.

Easy to construct storage.

Very useful way to create more storage space for little money. I feel I got my money's worth with this purchase. I used one for a bookcase and art display. I used one shelf set to turn a small closet into a pantry storage area. Easy to put together. I'm very satisfied with this purchase.
