The Best Convertible Car Seats
GearLab spends tens of thousands of dollars crash testing car seats at the same certified testing lab the US Government uses for its safety certification testing. We bought and crash-tested the top 22 convertible seats in this update to find the best. We conduct side-by-side tests of each convertible car seat over several months to determine the best in metrics like crash test performance, installation, ease of use, quality, and more.
Our favorite seat that is best for most families is the Graco 4Ever DLX. This reasonably priced car seat has one of the best crash test analysis scores, is easy to install, and super easy to use.
If your budget is a little tighter, but you worry about crash test results, the Graco Extend2Fit 3 in 1 costs less than the 4Ever but provides a similar crash test result. While somewhat harder to install, it offers a comfy seating area and quality materials.
We've tested more than 200 car seats, including 52 convertible seats. If you are not sure which kind of car seat is right for you, check out our Best Car Seat Review for more details. If your kid is graduating from a convertible seat, our booster seat review is perfect for the next stage in safety car seats. Not ready for a convertible? Infant car seats is where you should look for the best options designed with little bodies in mind.
