What comes after a high chair?

DS hates the high chair these days 3/4ths of the time. He likes sitting in a regular chair better...but is obviously not tall enough or steady enough to not have some sort of restraint. What comes next?

We have this booster & love it!

A booster seat with a belt.  You put it on the regular chair (it should have belts to strap the booster securely to the chair and to strap your LO into it).

I just bought Casey a cheap booster from BRU for about $13. I forget the brand but it's working well so far.

Our high chair (Fisher Price Space Saver) converts into a booster.
