The 15 Best Convertible Car Seats UK Reviews 2021

Unlike an infant car seat, which is only used for the first few months, convertible car seats can be used from infancy through toddlers.

They can accommodate both infants from 5 years and toddlers over 20 pounds. As your little one gets older, the seat can be converted from the rear-facing position to the forward-facing position.

Also, convertible seats have extended usage, and they can meet the growing needs of your child.

However, just like choosing any other car seat, figuring out the best for your child’s needs can be overwhelming. This is especially true due to the numerous brands of convertible car seats in the UK market.

This article will provide you with a review of some of the best models in the market. Also included is a buying guide discussing the key features to consider when making your buying decision.

What to Look for When Choosing the Best Convertible Car Seat UK

Buying a convertible car seat for your kid can seem overwhelming, especially if it’s your first one. When looking for the best convertible car seats, there are several factors you need to take into account.

Comfort Features

When choosing a car seat, you want to ensure that you keep your child’s comfort in mind. Comfort is one of the most important aspects especially if you are planning a long trip.

Comfort is also essential since your child could spend up to three or four years on this seat.

You want a seat that has plusher fabric and well-padded straps. The fabric should also be anti-bacterial and breathable for adequate air circulation.

If you want a seat for new-borns or infants, make sure that it includes infants inserts. Generally, inserts are designed for comfort and to provide adequate support for your baby.

Safety Features

Most convertible car seats adhere to the safety standards set by the government. Nonetheless, you should look for extra safety measures like additional shock absorption and a built-in levelling system to ensure your child is kept safe through the ride.

Side-Impact Protection

This is another key feature that you should keep in mind when scouting for the best convertible car seat for your child.

However, it is important to note that the side impact protection may vary from one model to another.

While some seats are designed with single-layer protection, others have double-layer protection while other models have side impact absorbers.

Also, note that this feature could add to the cost of the seat.

Ease of Use

A good convertible car seat should include features that make it easy to get your kid in and out of it such as harness holders. Also, it should be effortless to get the seat in and out of your vehicle.

Convertible car seats with hard-to-use features will not only ruin your experience with the car seat but also comprise your child’s safety.


The convertible car seat you choose should be designed for long term use to grow with your child.

It is highly recommended to keep your child in the rear-facing position for a long time. This is because it is the safest way for them to travel.

Therefore, it is vital to look at the weight or height requirement of the car seat before you make your purchase.

Make sure that it has an extended rear-facing weight range so they can use the seat for a long time, saving you money in the long-run.

Recline Adjustment Location

Every convertible car seat has been designed to recline, allowing your baby to seat in a more relaxing position.

However, more expensive brands have conveniently placed the seat recline adjustment for ease of use. For these models, this feature is located at the front of the seat. Moreover, you should consider seats that offer several recline positions.


While this a paramount factor, it is unfortunate that most parents assume it. Before you head out to purchase a new car seat, make certain that you know the size of your back seat, including the length and width. This way, you can pick a model that will comfortably fit in your vehicle.


Price may also be a factor to consider especially if you are working with a tight budget. However, it should be your last consideration since cheap models lack useful features that will provide more safety and comfort for your child.
