Booster seat for 3 year old

[Cuppasoupmonster]

Hi

DD is 3.5, average height and weight, still not quite big enough for dining chair even with a cushion but she seems too big for most booster seats like her current Chicco one.

Any ideas please?

Mine have always had a cheaper version of the Stokke Tripp Trapp chair which has grown with them.

My friend had a chair like these for hers when they weren't big enough for the usual chairs: www.ikea.com/gb/en/cat/junior-dining-chairs-45815/
