1) Place highchair on chair with non slip mat facing down onto the chair and the rest onto the back of the chair. If using the extension strap attach to one side now.
2) Sit the child onto the chair. It is best to stand behind the chair so you can hold the child at the same time.
3) The small strip goes between the childs legs and the long strip wraps around the child as high as possible up under the arms. It then goes through the slats or around the chair if using an extension strap.
4) Do up the Velcro around the back of the chair. Fasten tight.
