Edit to add: Posh Baby has reached out to work with me on the car seat safetly issue. They did not have to, since I agreed to their policy when I purchased the seat. It just shows they truly do care about their customers! I've updated to 5 stars because they really did put in extra effort for me.
This place does have amazing people and a great selection. I just wish they had a better return/exchange policy on car seats. But I tried the fit of the booster in my car, had a worker look, and it seemed fine. I bring it home, after a couple times of my kid trying, the seatbelt easily gets caught and just won't retract. Nothing wrong with the seat, it's just not compatible with my car. But now I have an expensive car seat that's not safe to use in my car and won't fit in my husband's car. :( I wish I had gotten it elsewhere with a return/exchange policy.
