These rubber dampers are located between the swing and the tree. This ensures that the tree bark does not rub with the steel triangle and thus does not scratch it. Order a new set if the rubbers are lost or in poor condition.
The wooden seat with Weltevree logo is attached to the ropes of the Swing or the Serious Swing. When the seat needs replacement you can order a new one here. Attach it by detaching the ropes from the hooks, swap the seat and enjoy your surroundings from the swing.
