My son is 23 months old (well nearly) and he's resisting getting in the high chair but he's too short for a normal chair. All the boosters I have seen look pretty small and he's actually ok balanced on a chair without a strap nowadays but I'm not sure he'd be ok without a strap with a booster (but I'm not convinced he'd sanction being strapped in either.)
What do / did you all do? Use a cushion? Any recommended larger booster seats?
