A soft place to get down on the floor is essential for kids. But if loud colors and patterns clash with your decor, check out this Alphabet Rug.It's got all the ABCs but isn't childish looking. The pale grey background and playful letters is a great balance between whimsical and understated. It comes in a variety of sizes. You can find it here.
Also check out the walls in the photo. We love the idea of using maps as wallpaper.
