What is the maximum recommended load that can be safely placed on the Stokke® Tripp Trapp® chair?
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.
For GS Mark (Tested Safety) certification, the Tripp Trapp® chair was tested according to various standards. One of these is a standard called DIN 68 878, which is a quality norm for adult chairs. This standard involves a dynamic test where 85 kg is placed on the seat, which is then tilted backwards 6000 times. The Tripp Trapp® chair passes all the tests in that standard, which means a load of up to 85 kg can be safely placed on the chair.
