The growing high chair 'Sit Up Flex' made of wood offers your child ergonomic, safe, and tailored seating comfort from a young age all the way into adolescence, with a long usage and lifespan. Regardless of table height and age, your little one will find a place with this versatile chair and actively participate in family meals. For toddlers, it starts securely at the highest level with a safety bar and harness system. After the easy removal of the bar and harness system, it gradually grows into a youth chair—supported by the height-adjustable and removable seat and footrest. Compatible accessories, such as a dining tray or seat reducer, are available separately.
