We only have counter-height (36") seating in our kitchen and didn't want a standalone high chair as it would take up too much space. We had a perch chair, but that wouldn't take her beyond 18-24 months and was awful to clean.Ultimately, we decided that the absurd cost of the Tripp Trapp made sense because it would take years before our little one could sit with us at the island on our backless stools for meals.... But the Tripp Trapp isn't counter height and the only commercial solution is from Europe at an absurd cost.So I found a Reddit post that suggested a Kaboost would work (and thanks to the others who reviewed the Kaboost and confirmed it would fit)!I can indeed confirm that it works, and while the Tripp Trapp extenders won't work with it, I find that the Kaboost makes it much harder to tip as well: honestly as well as the extenders!Absolutely would recommend the Kaboost if you want a Tripp Trapp at counter height.Our baby is particularly tiny and doesn't fit any chair on her own, so we used the infant insert from the Uppababy Mesa we already had to bring her up a touch higher, but it's not necessary if your baby is a normal size.
