Hook Rafter Yellow/Gray Bulk Pack - Heavy-Duty Construction Hooks for Roofing, Scaffolding, and DIY Projects - Perfect for Builders and Contractors

For anyone who has used a highchair that offers no place to hang the tray and prefers not to have to stop to take off the tray (which often times happens once you have already picked up the child who needs to be put in it), this hook works well on the back of most chairs. Check to see if there is somewhere to use it before purchase, and if you get it, use the silicone part to hold the tray.
