About this item

Product details

The Mainstays 8 Cube Storage Organizer is a black cube bookcase with eight open cubbies for organizing books, clothes, office supplies, craft materials, photos, collectibles, and more. You can set it up vertically or horizontally, so it can adapt to the space and layout you have in mind, whether that's standing tall against a wall or lying low along a bench or window. Its mixed back-panel design pairs four open-back shelves, which leave room to route cords through, with four closed-back shelves that give certain spaces a more contained look. For a tidier, filled-in look, it's compatible with Mainstays 10.5 in x 10.5 in collapsible storage bins, which are sold separately. At assembled dimensions of 23.7 in W x 11.73 in D x 47.01 in H, it's sized to work in a home office, bedroom, living room, playroom, closet, dorm room, or entryway.

Wonderful storage

I got this to hold books! It works great! It only took about 20 minutes to assemble! I put it in a closet and turned it horizontal and placed it on top of some 12” deep white upper cabinets!

Sturdy storage

This is a solid piece of furniture and easy to put together. I bought a set of the basket containers and it makes it very versatile for how you want to use it. You can buy more baskets and keep everything hidden or not have any baskets for full displaying if that's what you want. I bought a couple of them and am using them in my closet. I'm very happy with how well they fit in my space and how sturdy they are. Much better price than IKEA.

Great for the price!

This is a great cubbie storage organizer! it wasn't difficult to put together either instructions come in a booklet or there is also a video you can watch on YouTube. I was a little disappointed because one of the edges was chipped not terribly noticeable but I had already put it mostly together so I wasn't going to let that stop me. It holds all the stuff i was looking to store in it. very nice for the price!
