So we have the chair now has four months in use, and are happy at and for themselves with the function. The chair is extremely robust and is super stable even when our little girl wriggles back and forth in his chair he does not wobble a bit. Also the belt system is great. But what unfortunately does not go is the cleaning of the chair, there are simply too many corners where accumulates eat and which are accessible only with difficulty. I clean the chair regularly but that always takes about an hour to complete because you have to disassemble the chair with upholstery completely. And even after the Reinigungsprodzedur I am not satisfied with the result afterwards. And since I do not mean by the most important for hygiene, I can speak for the chair not advise .. and assign only two stars due to the first-mentioned points
