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.

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.

This is the deal of the decade!

First, the packaging of this bookshelf is really impressive. They've added filler to ensure that there is no damage to the parts. Have you ever had to return a flat pack item because it was damaged? It's a total PAIN! So no chance of that here. The instructions are clear with plenty of words and diagrams to help you along if you need it. It goes together in no time at all and is very sturdy. All this for less than $30!?! How? I use these in the closet for shoe storage and they're beyond great.
