Best Group 2/3 Car Seats in the UK – 2021 Reviews

Best Group 2/3 Car Seats: The importance of a car seat cannot be denied. There is a reason why car seats are a mandate in many countries. The functionality of car seats in saving the lives of children is phenomenal. The ever-increasing number of cars on the roads and increased power in the engine has lately contributed to several road mishaps. It is also a fact that lives are getting more dynamic each day and that requires babies and children to be on the road.

This requires better security measures to keep the children safe. While market shelves overflow with numerous options, it is often difficult to decide which one to buy. The confusion comes in especially when the baby is 2-3 years of age and has outgrown the newborn car seat. This article focuses on helping you find the best Group 2/3 car seat.

Top 3  – Best Group 2/3 Car Seats

Why is the best group 2/3 car seat required?

We often wonder that a 2-3-year-old has the good body control and can seat, then why not a normal seat belt and why a car seat. This is because a well-fitted car seat takes the risk of an injury down by nearly 67% in case of an accident. Also, a 2-3-year-old doesn’t have adequate strength to sustain sudden jerks. Their body isn’t as strong as the adult body and thus, adult seat belts are not ideal.

Here are some reasons why the best group 2/3 car seat is an absolute must for your toddler:

  • A high-speed crash can be life-threatening because the body and brain of toddlers are still developing
  • Kids car seats prevent their light and delicate bodies from flying across and banging when there are bumps or brakes are suddenly applied
  • A child is not firm on a seat. Nor does it concentrate on holding well. This puts them at risk of falling off in case of jerks

A child car seat is a perfect way to keep the little body well secured and prevent injury by banging against car doors or windshields. They also offer cushioning in case of bumps and hence prevent fatigue. We as parents always strive to do the best for our children and thus a car seat is quintessential.

What to look for on your hunt for the best group 2/3 car seat?

5-point harness: A 5-point harness is a very important component that ensures the safety of your toddler in a kids’ car seat. It is a safety belt that secures the baby by clipping across the chest, over the thighs and between the legs. It helps keep the child secure and restrains in the case of an accident. Although not a must, but a padded tray in front of the belly is also a good idea as it offers added security in case of an accident and can help keep toys during the travel.

Tether attachment: A tether attachment is an extra strap for safety as it clips from the top of the car seat to a clip anchor in the car. All new cars and vehicles come with a tether anchor. If you already have a car seat without a tether attachment, you can also buy a tether kit.

Sufficient padding in the car seat: Most children resist car seats at first. Soft cushioning around their head, neck, and back will ensure a smooth riding experience and also minimize movement within the seat.

Machine-washable seat cover: It is a no-brainer that toddlers are messy and will eat and likely puke more than once on the car seat. It can be an expensive affair to frequently get your car seat professionally cleaned. It can also deteriorate the cushions. A machine-washable seat cover is the best way to keep muck at bay and maintain the hygiene of the child car seat.

Compatibility with your car: It is always wise to check well in advance if the car seat you are ordering is compatible with your car. Some old cars do not support newer car seat models.

Final Words:

The ultimate choice of car seat depends on several factors including your car, how frequently you go out and how do you plan to use it. There isn’t a one size fits all approach. However, if you are looking for the best group 2-3 car seat that is sturdy, can be easily installed and will keep your child safe and comfortable we vote for Britax Römer KIDFIX SL Group 2-3 (15-36kg) Car Seat – Cosmos Black. While the others are equally efficient, this one is highly rated and recommended by users.

While doing research into how I could handle becoming a first time mum and juggle my studies, I found there wasn’t a lot of help out there for ‘student mums’. So I thought I’d create a blog to help those who might be struggling to get the support and help they need, while writing about life as an expecting mum, a student mum and life after!
