These are our window benches made from Ikea Expedit shelves. See my tutorial here: Ikea No-Sew Window Bench Tutorial.
Almost as important as the fabric you choose for the cushion are the storage containers you choose to go inside the openings. These openings are about 13'x13'x15' so pretty large. It's hard to find that size of storage bin/container for cheaper than $15. And we had 10 spaces to fill! So we were definitely looking for something much more affordable.
These storage containers are actually made to fit this exact shelf from Ikea. I didn't initially see them in the store when I was there, but found them online and had them shipped to my house. They are Ikea's Drona Box. They fit perfectly. And the best part? They are only $4.99 each! It was impossible to find another storage container close to that price. They come in several colors, but we went with white. I've even seen other people get these containers then spray paint numbers/letters/etc. onto them. The possibilities are endless.
For our 2nd window bench that is in our living room, I wanted storage containers that looked a little nicer. Don't get me wrong, the Ikea boxes look great and will hold up for a long time, but I saw another container that I instantly wanted. It's Target's Theshold Storage Bin. They also come in 3 colors, we went with the Natural color. Only down side is that they cost $12.99 each. I have a Target Red Card so I got an additional 5% off. You can wait until they go on sale if you'd like to chance getting the color/amount you want.
Did I mention that they hold A TON of stuff? It's an easy and convenient place to store toys, blankets, books, etc.
