This swing seat is great. Start with all the components in place (as supplied), and then remove first the T-bar, and then the back support. This seat will give approximately 5 years of usage until your child is ready to move up to a flat wooden swing seat. Safety harness included. Ropes are made from 12 mm polyhemp, they look and feel just like really rope but will not rot. Rope length is adjustable. Fixes to your swing beam with 40mm steel rings.
