Booster seat for 3 month old?

Is there anything out there like a booster seat that attaches to a kitchen chair that would support a 3 month old? He’s not close to solids but he loses his little mind when the whole family is eating dinner at the table and he’s excluded. We put him in a bouncer on the floor next to us but he cries until one of us holds him during dinner. He has very good head control but obviously isn’t sitting. I’m 100% not interested in a traditional high chair, our kitchen doesn’t have room for that and I suspect he wouldn’t like it anyway.
