Hi piyo,
Ikea high chair + tray should be not more than $30, something like $16 + $13. I only remember it at less than $30. I need to get 2, so got to go for something more economical. And, Ikea ones are easy to clean and more of the restuarants outside use it as well. So, in case of dinning out, chances of baby getting use to it is higher.
If you are only getting 1, maybe you would like to indulge in something better or with leg rest. Ikea highchair has disadvantage as it has no leg rest and cannot be 'folded' when keeping.
My girl is Rae, that's why I can't put her in bumbo as her legs are too fat. Have email you.
