About this item

Product details

The Mainstays 5-Cube Storage Organizer gives you five open storage cubbies arranged in a slim 5x1 layout, making it a flexible way to keep books, office supplies, craft items, photos, and everyday essentials within reach. Because it can be used vertically or horizontally, you can set it up to suit the wall or floor space you have, whether you want a tall, narrow column or a low, lengthwise row. The cubbies combine two open-back and three closed-back shelves for different storage needs: the open-back cubbies leave room to route cords for electronics, while the closed-back cubbies help keep stored items in place. If you'd like a more finished, tucked-away look, the organizer works with Mainstays 10.5 in x 10.5 in collapsible storage bins, sold separately, so you can plan a setup that mixes open display with concealed storage.

Great Storage!

This is maybe the 6th or 7th item from this line I have ordered and I cannot rave enough about how much I love cube storage! I put these in my closet and use instead of drawers. I have several of the cubbies that fit in the cubes and they work so well to organize more easily than large drawers. Bonus - these units stack! Super fast shipping and easy to assemble.
