For a long time, our bed was sans headboard: We had a simple West Elm lowriding bed frame pushed up against the wall. It wasn't until we made the leap and got a "proper" bed frame when we realized how very nice it was not to have the throw pillows constantly sinking in between the cracks of the mattress and the wall. But despite our affection for our new bed, we still have a soft spot for Japanese-style low beds with no headboards, like this one photographed here...
This bedroom looks so calm and inviting, though probably not so practical for our habits, i.e. reading before bed. Still, it's pretty to look at and the light flooding through the windows is enviable. Sigh.
