This really is true. The EXPEDIT shelving unit from Ikea is so versatile, sturdy, and nice on the eyes. Right now, I own a total of four shelves simply because they are so awesome... and because I have a truckload of books! Sadly, Ikea no longer sells the "Expedit"; they have replaced it with the KALLAX. It is just as nice, comes in a wonderful slew of colours, and costs only $79.99 for a unit of eight cubes (it literally is identical to the former!) I should also mention that they are super easy to put together! I have two of the double shelves on either side of the fireplace, which provides great storage and mimics built-ins at a fraction of the cost! In the corner of the room and beside one of the double shelves, I opted for a single to maximize storage usage.
On these shelves I display my many books, cameras, and pieces I've collected from family members that are vintage. They're clean, and sturdy. I also use wicker baskets, which are made for both the Expedit and Kallax shelves and retail for $12.99 each. I use them to store office supplies, odds and ends, and dog toys for Mr. Bingley.
If I needed a room divider, I could have used the shelves as well. What I did need was immediate storage in a slender kitchen, and the Expedit fulfilled that need perfectly. I placed the double shelf horizontally, and opted for not adding feet because it was the perfect height. Ikea sells different finishes of feet as well. The shelf stores things like bread and nuts in the baskets, and holds some appliances on the top and inside. Its fully functional for kitchen use, especially when your kitchen is on the smaller side.
I definitely recommend the new Kallax and old Expedit shelves to anyone who needs storage and purdy functionality at a great price.
