Car seats for 19 month olds?

I’m shopping around for a new car seat for my lil guy. He’s 19 months old and quite the ham. Pushing 35 lbs and a lil over 35 inches. We’ve had his current one since last summer and I’m honestly just not a fan of it in general anymore. I think it worked better when he was smaller. What kind of seat are using for your 18/19 month old?
