What seat is it?

Usually it’s in your instruction manual or if you google your model or check manufacturer

Some are even adjustable in height

You should see your model name on car seat or the box you had or just google the company and call them yourself they even usually include warranties including notifications if it’s recalled or safety concerns

They are not all the same so you would have to check the specific seat. I have a nuna pipa and it goes to 35lbs but there are others that only go to 22 lbs
