Great little shelf unit
Color: White, Size: 9.3 D x 19.5 W x 41.8 H in
Easy to put together by myself. No issues. Took less than an hour to completely assemble. It’s perfect for purpose intended. A top shelf closet organizer for knick knacks and other smaller items.

Great for classroom organization

These shelves are perfect for organizing my classroom library. The cubes are a little smaller than I expected, so they don’t fit larger picture books well. I was able to make it work by using bins inside the cubes and slanting the bigger books, but just know it’s best for regular-sized books. Since they’re a bit shorter, I stacked two together and it gave me the height I needed.
Overall, they look great, were easy to set up, and hold a lot of books in an organized way. My students can easily find what they need, and I really like the clean, simple style.

Great for the Price
Color: White, Size: 9.25"D x 19.49"W x 31.5"H, Color: White, Size: 9.25"D x 19.49"W x 31.5"H
I needed a cheap little bookshelf for this small play area. The shelf was relatively easy to assemble by myself, and it's sturdy enough to stand on carpeted flooring. I didn't bother installing the safety wall mount because I live in a rental and I can't screw things into the walls. The bookshelf is too small for standard storage cubes, so I purchased a couple of 9-inch cubes from the Dollar Tree and they fit just fine. I might rearrange the contents later.
