How to buy a cheap car seat

We’re all about saving money here at GoodtoKnow – especially when it comes to expensive products, so we’re sharing some of our top tips for buying a car seat on the cheap.

  • Online vs in store: Make sure you view the car seat and try it out – even in your car, before you buy in store or online. Some stores have exclusive discount deals that are only available online or the other way round, only in store, so its always worth doing your research before buying.
  • Sales: If you want to save a lot of money in one go, holding off until there are sales on is a great idea. Some of the most popular include Black Friday, Boxing Day sales, January sales and end of season sales are great for bagging yourself a bargain!
  • Vouchers and discount codes: It’s always worth having a look on Google to find out if there’s any recent discount codes for the store you’re buying from – even if its free delivery, it’ll make a difference to your overall budget.

Car seat safety

When buying a car seat, you need to look out for either the ECE R44/04 approval or the ECE R129 approval label, both of which are current approval standards for children’s car seats in the UK.

Our car seat safety guide has all the info you need to know about keeping your little one safe in the car, as well the key things to look out for when buying a new one.

Is a second hand car seat ok?

If you do use a second-hand car seat, you must be certain of its history and test it in your car as car seat sizes vary based on your baby’s age and weight. It must be properly installed, tightly secured with very little movement. Group 0 rear-facing infant carriers (for better head and neck support) are for newborns up to 9 months (up to 10kg/22lb) and Group 0+ for newborns to five to 18 months (up to 13kg/29lb).

Leading mum blogger at Liz Jarvis says, ‘There are some things you should avoid getting second-hand for safety reasons: Your baby’s mattress and their car seat, for example. It’s very important these items are bought brand new, particularly in the case of mattresses, and car seats should only be second-hand if you’re absolutely sure about their previous history.’

For safety reasons and regulations we’d recommend you opt for a brand new car seat.
