When choosing a car seat for your child, safety is undoubtedly the top consideration. But what about some of the other additional features that may be trickier to compare? It can be hard to know how to sort what features you really need from those that you can live without, especially if it is the first time you have purchased a car seat. A key feature that many parents find extremely useful is opting for a convertible seat that can be adjusted as your child grows and can be used rear- or front-facing, or simply as a booster seat. That way, you don’t have to waste money on buying multiple different products or working out which is the best seat for your needs each time.

Here are some other features that are worth looking out for when it comes to purchasing a convertible car seat:

  • First and foremost, check that the seat has been extensively safety-tested and meets or exceeds all minimum US safety standards
  • Look for products that claim easy installation, as these will save you time and effort when taking the seat in and out of the car
  • Ensure the product has fully adjustable headrests and straps as well as adjustable seat height, so it can fit your child comfortably and safely as they grow
  • Check for extra features such as removable seat covers and pads for easy washing, or integrated cup holders that allow for drinks or snacks to be accessible for your child even when you are driving
  • Select a seat that has multiple recline positions to ensure the best level of comfort for your child and versatility of fit in different vehicles and at different positions (front- or rear-facing)

To make your search easier, we’ve selected our top five picks of the best convertible car seats on the market right now.
