The chair that grows with your child into adulthood. The intelligent, ergonomically mature design encourages the child to move, play and discover independence without compromising on safety and protection. Tripp Trapp is adjustable to the size of your child. You can be sure that your child always eats, plays and is active at the right height and that the feet find the right support at any age. The unique adjustability of Tripp Trapp means that you can always ensure that the child's elbows are at table height, that the feet are supported and that there is space between the seat and the child's calves. The thighs should sit up so that the knees form an angle of about 90 degrees. For babies, a two-finger wide space between the back of the knee and the seat should be free for air circulation. For slightly older children, approximately ¾ of the thigh should rest on the seat plate.
