Mommo Design has a bunch of inspiration for girly reading nooks. These quiet corners contain fluffy pillows, rugs, cushions, usually a canopy, and of course lots of books. I think the idea is very cute and I'd love to do this for my daughter's room.
Yes! Adults need to have fun too! Any slide for adults in a house is a great idea, but this one contains a water slide. Excellent choice of transportation and you can even get a shower on the way out of bed going down to get breakfast!
I like the idea of having a simple shelf above the head of my bed. This would work with the idea of the box lights instead of a headboard - they could hang down from the shelf! And that shelf could hold all of my most treasured books!
