If you find that the leg space of the current, plastic Stokke® Tripp Trapp® Baby Set™ is too tight for your child, please make sure the Tripp Trapp® chair itself is adjusted correctly (with the seat plate installed according to the instructions in the Tripp Trapp® user guide) and the Baby Set™ fitted according to instructions in the Baby Set™ user guide.

On a general note, the new Stokke® Tripp Trapp® Baby Set™ has undergone rigorous testing and had been in use in the US, to high customer satisfaction, for several years before its introduction in Europe in 2011.

It was designed to meet revised international safety standards for high chairs (used between 6 and 36 months of age) and to fit the average child.

Of course, it may well happen in some cases that a child grows faster than the norm and outgrows the Baby Set™ before it reaches the maximum age advertised.
