I find interior swings especially charming when incorporated into children's spaces. Since this room isn't in a full-time residence I was able to push boundaries and do something truly fun that I wouldn't typically design for a day to day space. Weekend whimsical.
Rug: Pottery Barn
The key with swings in spaces for kids is to not hang them where they can become a "swing," but rather closer to a wall where they become a fun place for a kid to hang out and read a book or play with a small toy. I had this one professionally hung into the ceiling beams about ten inches from the wall.
Have you used swings in interior spaces?
