At what age and size did you switch your kid to booster seat?

My 6 year old is 50 lbs and probably somewhere around 3’9-3’11 and I’m wondering if it’s time to switch him to a booster seat. I’m really worried about if just the seat belt instead of the harness will be good enough if we were god forbid going to get in a bad crash. What age and size did you switch your kids to a booster seat?
