Consider the material of your car seat. All seats are not created equal, and the quality of the fabric can make or break a good seat. If you're looking for something that will last for years and be easy to clean, canvas or leather are two great options. However, if your child tends to spill things, there is nothing wrong with opting for a fabric that can take some punishment.
When considering durability, think about how often you'll use the seat, how many children you plan to use it for, and how much weight it can carry. If you're planning on using this car seat multiple times per day or transporting two kids in one go, then be sure to get one that's built with high-quality materials that can withstand years of wear and tear.
Once you have chosen the right car seat for your child, it's time to ensure that it will be comfortable for them. There are a few things you can do to check this. First, sit in the car seat yourself and get a feel for how much room there is. If you can't fit comfortably in the seat, neither can your child.
