Replaced Dresser

Easy to assemble. Liked it so much I bought a second one. Both are used in a walk-in closet to replace a dresser. Purchased fabric bins for the bottom shelf. Overall, a great replacement for big, bulky dresser. Suits the purpose, and the white color gives it a very clean, minimal look to match the white walls.

Cute, Sturdy Shelf!

Bought to go in my home office and immediately loved it. It was very easy to assemble and took me only about twenty minutes to assemble. I added some super glue to make the corks extra stable, and it looks great in the room. Will definitely be purchasing another for the office.

Simple assembly - great little bookshelf

I have used these little bookshelves for many things throughout my home. I put three of them together and mounted them atop a box I built to make a low library partition wall (I joined all the backs together by mounting luan-board across the whole span). One is used in our bathroom with multiple cube (fabric) containers to corral miscellaneous items. Two more flank our TV console.
