Tripp Trapp® is approved by various testing and certification organizations around the world - including, but not limited to, GS-Mark and JPMA certificate.

In order to back the "chair for life" claim, Tripp Trapp® has been also tested beyond the typical 110 kg/242.5 lbs limit of adult chairs by modifying conditions of various strength tests to become even more stringent. Passing results prove Tripp Trapp® can withstand loads even up to 136 kg/300 lbs.
