The zome will always be able to twist a little bit depending on anchorage and usage. We refer to “spinning” as repeated full rotations of the zome. Generally speaking, most adults prefer no spinning. It is usually most comfortable to swing to and fro while always facing the same direction, and this accounts for the majority of the installations. Therefore, we usually recommend to not install a swivel.
However, if young children will be using the zome or it will be in an unsupervised area with children, it will most likely receive of A LOT of spinning. If this is the case, we recommend you do install a swivel between the zome and the anchor point. Without a swivel, excessing spinning can weaken the hanging components and create an unsafe condition.
Adults relaxing = no swivel Children playing = swivel
