Since the installations and adjustments are easy to make you get a very safe chair. You won’t skip that necessary adjustment when you can easily make it. Expertmom gives thumbs up for this. In fact, the installation process is so easy that you won’t even sweat from it on a hot summer day.

Comfort and Design

This review of the Britax Marathon 70 car seat will also have to point out that this chair is comfortable both for you and your child. It fits well also in a smaller car. You don’t have to compromise on the space which is important when you need to transport several children, groceries and other things. The appreciation of the design is really up to your taste but most would say that this is a nice looking car seat that doesn’t easily look dirty or worn thanks to the colors and the fabric which handles wear and tear well.

This car seat is also easy to keep clean and you can either clean it off in the car every now and then or bring it into your house for more serious cleaning. The fabric dries fast so don’t be afraid of getting it wet! Perfect when you need a clean car seat fast.
