Kaboost is portable chair booster and acts as an add-on that elevates the chair to a higher position. It is made from plastic and rubber and snaps on to each individual chair leg. The Kaboost has 2 height positions, similar to a standard booster seat: 4.5 inches and 3.75 inches. With Kaboost, your child can sit at the table like a grown up and easily reach his or her food, join in conversations and be present with the rest of the family. Kaboost fits on most four-legged chairs, either with round legs or square legs and can be stretched up to 30 inches across. It snaps on to each leg using a spring-loaded action and stays attached when the chair is moved.
