If you require a quick answer, the best group 2/3 car seat is the CYBEX Solution X-Fix. It can be installed with or without the ISOFIX system and it provides superior comfort and protection for your child. However, if you are on a tight budget and require a cheaper alternative that’s still developed by a reputable brand, the Graco Junior Maxi is the best option.

To rate the group 2/3 car seats within our roundup, we based our recommendations on testing, our experience of using multiple car seats, the latest research and several factors. Some of the factors that we took into consideration included the ease of installation, recline and headrest positions, build quality, additional features, weight, warranty and value.

Best Group 2 3 Car Seat Overview

Within the group 2/3 category, you may notice that there are many backless booster seats available and they offer great portability and are often cheaper too. However, it’s important to note that for your child to use these types of seats, they must be taller than 125 cm and weigh more than 22KG. This new law came into force in the UK in February 2017.

Below is a list of the best group 2/3 car seats that are all forward facing and provide plenty of comfort.

  • Available in 4 different colours
  • Built-in side impact protection
  • Patented reclining headrest
  • 11 position height adjustable headrest
  • Removable and machine washable cover

It’s easy to install with or without the ISOFIX system, provides plenty of comfort and is built to the highest of standards.

It’s also one of the lightest, which is a great bonus if you intend to install and remove it regularly. The only potential drawback for some parents is the fact that it doesn’t feature the desirable ISOFIX installation.

4. Best i-Size: Maxi-Cosi Kore ISOFIX Seat

The Maxi-Cosi brand offer a number of highly rated i-Size car seats but the Kore is the brand’s new and improved group 2/3 car seat. The main improvement made to this particular seat when compared to its predecessor is that it’s i-Size complaint.

5. Best All-Rounder: Britax Römer KIDFIX Groupe 2/3 Car Seat

By far the most expensive group 2/3 car seat within this article is the Britax Römer KIDFIX and although it may be out of budget for some, there are plenty of features that makes it a worthwhile investment. This is because it’s a high-back booster seat that’s designed to provide maximum comfort and superior protection in the event of a collision.

Although the brand offers a similar group 123 car seat, this particular model is ideal for children from the age of 3.5 to 12 years old.

  • Choice of 7 different colours
  • Enhanced side impact protection
  • Added fourth contact point to the seat belt
  • Easily removable backrest (ideal for when your child reaches 135 cm)

Overall, the Britax Römer KIDFIX is a well-made, comfortable and ultra-safe car seat. The addition of the extra contact point for the harness is also another great bonus because it prevents your child from slipping down if they go for a nap. Apart from the expensive price tag, there isn’t much to dislike about this particular seat.

6. Best Booster: Peg Perego Group 2/3 Booster Seat

The Peg Perego Booster is a unique group 2/3 car seat because it simply consists of a base, which is suitable for older children who are the right build for the car’s seat belts. In terms of the design, the backless construction provides plenty of comfort and it safely secures your child without restricting them with side bolsters.

  • Dual layered padding for comfort
  • Installation via ISOFIX or the car’s 3-point seat belt
  • Double padded armrests
  • Lightweight at just 4.0 KG
  • Integrated handle to easily carry it around
  • Relatively expensive
  • Not very aesthetically pleasing

Unlike many of the alternative booster seats available, the Peg Perego offers far more comfort and also features the ISOFIX system. It isn’t the cheapest but the superior build quality, design and comfort are worth paying the extra for.
