I'm thinking of buying a Britax First Class Plus, which goes from newborn to 4 years old. This is my first baby so I've never used a car seat before. They are around £79.99 to buy online and £99.99 to buy from a store where they fit them for you. Every penny counts at this stage, but safety is obviously the most important thing.
Can anyone advise how easy they are to fit? Is it better to get them fitted by a store? Or can it be done easily yourself? Thanks.
