GREAT (ANYTHING) SHELF!!

I Love it!! Was easy to put together. Doesn't take up a lot of space. You can adjust the shelves. Has a strap attached to back, so it won't tip over. Easy to move around, once it's put together. Sturdy!

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 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.
