Swing safety is a very complex issue. There are three different types of swings, placement requirements, use zone requirements, requirements for the type of fasteners and suspending elements, and surfacing requirements that must all be taken into consideration.
The different types of swings include single axis or to-fro swings, multi axis swings, such as tire swings, and combination swings. Combination swings are a new style of swing for the U.S. They have been used in Europe for some time. The swings are designed for two people to use at a time.
