If you have a Tripp Trapp high chair, you may be wondering how to tighten it. There are actually two ways to do this, depending on which model of Tripp Trapp you have.
If you have an older model of the Tripp Trapp, there will be a knob on the underside of the seat. To tighten the chair, simply turn the knob clockwise until it is tight enough for your liking.
If you have a newer model of the Tripp Trapp, there will be a lever on the back of the seat. To tighten the chair, push down on the lever and then pull backwards towards yourself. This will tension the cords and secure the seat in place.
