Top 5 Best Convertible Car Seats – Convertible Car Seat Buying Guide

When it comes to Convertible Car Seats, there are so many options available it can be overwhelming as to which one is going to be the best for your little one. To help you out with this tough decision we have conducted some research and found the top 5 best convertible car seats on the market for you to check out!

Factors to consider

One of the first things you need to do is figure out what you need and want in a convertible car seat.  We think some important factors to consider include:

  • Cost – Set a budget of how much you would like to spend. Car seats do tend to be more expensive, but they do provide Imperial safety while in a car!
  • Safety Features – There are so many car seats available that offer different safety features. Be sure to read all product descriptions and make sure they meet safety standards.
  • What age range does the seat suit? Many car seats fit only a particular age range. However, there are convertible car seats that will fit babies rear facing from birth right through until they are 5 (or older) forward facing. This option is way more budget friendly.
  • Easy to Install – You want a car seat that is safe and secure but also easy to install.  Read the installation instructions to ensure it fits your vehicle.
  • Lightweight or heavy? – Car seats can come in a range of weights. If you travel a lot or need to move the car seat around lots of times, it may be better to invest in a lightweight car seat.
  • Check the features of the seat – Convertible car seats always have extra features including more padding, a cup holder, or perhaps a better belt buckle system.
  • What is it made out of? Look to see if the fabric is soft, durable and breathable and that the material is easy to clean.

Buying Online vs In-Store

Buying online can often save you money and time especially if you cannot make it to the shop. However, it is a good idea to check out car seats at a store first!  This allows you to get a feel for the seat, to have a play with it, to see its features, and ensure it fits your car properly. Once you are happy with your decision then either buy in store or search online for the best and cheapest deal!
