We bought this seat because our almost 2-year long happy with book sitting on the toilet and the otherwise super jammed paper by NUK unfortunately in these long sessions nasty imprints leaves on the legs. Our son was very enthusiastic on the subject and wanted to try the seat directly. Our toilet a little shaky (made me more disturbed than him), the seat is quite small and the fit no comparison with NUK.
But what has absolutely annoyed me is that the red color has left our white toilet seat several streaks that I got off again only with persistent scratching and detergent. Went again good but in the long run I would therefore certainly scratch our own toilet seat and broken scrub. Therefore, the seat went back directly.
