What is a tree house without a swing? That's the question the expert designers at The 4 Kids asked themselves when they created the classic cedar tree house swing, much loved by children everywhere. Tree house swings from The 4 Kids, however, are not just for tree houses. They can be hung from the trees themselves, on playground frames, even under decks to provide hours of fun for two year olds all the way up to 12 year olds. Tree house swings are created using stringent safety standards and revolutionary materials that increase durability and decrease maintenance time.
