Best Convertible Car Seats of 2018 – Buyer’s Guide

A car seat is one of the most important aspects in keeping your child safe in moving car. Convertible car seats are unique in that they grow alongside your child. Meaning, they can transition to different positions, designed to take your child from infancy through elementary school.

A convertible car seat starts as a rear-facing for the beginning of a baby’s life, and then converted to front-facing when your kids are old enough. Some convertible car seats are all-in-one to include a booster mode for kids that are at least four years old.

Convertible car seats are the best option for parents as they will last more than just a few months, saving them the trouble of researching and buying a new seat each time their child outgrows the current one. They can seem expensive upfront, but when you consider the longevity of these seats, they are definitely quite a bang for your buck.

The car seat is super easy to install with just a click. You can use it as both a rear-facing (5-40 lb) and as a forward-facing (20-65 lb) car seat. It’s made of a steel frame with energy-absorbing base and a deep foam-lined headrest that would reduce forward movement during a crash.

As the name implies, this 3-in-1 car seat is built to grow with your child. It transitions easily from a rear-facing car seat (5-40 lb) to forward-facing seat (22-65 lb) to a belt-positioning booster (40-100 lb), making it the perfect option for first time parents.

This Grow and Go car seat comes with built-in Harness Holders that make it easier for you to get your child in and out of it. In addition, the Quick Fit Harness allows you to adjust the height of the seat, providing additional convenience when it comes to giving your growing child the best fit.

4. Graco Extend2Fit

Graco Extend2Fit Convertible Car Seat

The Graco Extend2Fit shares many basic features and specifications with the 4Ever convertible car seat. It features the same steel reinforced frame, 6-position recline, InRight LATCH system, FussFree Harness, and more. The difference between the two, however, is that the Extend2Fit supports up to 50 pounds rear-facing using a 4-position extention panel that pulls out on the front and provides 5″ additional leg room.

That being said, the Extend2Fit has also got to lose some features in comparison to the 4Ever. Specifically, it’s not an “all-in-one” convertible car seat as the unit lacks booster mode. It’s unable to transition to a belt-positioning booster, or a backless booster. This is probably why it’s $100 cheaper than its sibling, the 4Ever.

So for parents who are not interested in booster mode, the Graco Extend2Fit is definitely worth the money. The seat is designed for super versatility, comfort, reliability and ease of use. It’s also rigorously crash tested to meet or exceed US Standard FMVSS 213.

Product Specs:

  • Brand: Graco
  • Model number: 1993220
  • Weight: 23.8 pounds
  • Dimensions: 19.2 x 25.2 x 22.1 inches
  • Color: Davis

Pros

  • Rear-facing up to 50 pounds
  • Side impact protection
  • EPS energy-absorbing foam

Cons

  • No booster mode
  • Large seat may not fit in smaller SUVs

Best Convertible Car Seats - Buyer's Guide

    In the US, there are three main types of child car seats available on the market. They include:

    Infant Car Seats: These are for newborn babies up to 15 months old and are always rear-facing. Typically, these seats have a weight limit of 35 pounds, or until the crown of your child’s head is level with the top of the car seat.

    Convertible Car Seats: These work for children in both rear-facing (up to 40 pounds) and forward-facing (up to 70 pounds) positions. Remember that it is always safe to keep your child in a rear-facing car seat up to at least they are a year old. Some convertible car seats are actually 3-in-1 since they can transition to a booster seat.

    Booster Car Seats: These are for children who are at least four years old, or weigh at least 40 pounds. These seats come in high back and backless varieties, and as the name suggests, they boost lift your child high enough for your vehicle’s lap and shoulder belts to fit properly.

    Not all convertible car seats fit in a car, so it’s vital you take a look on the car you’re going to be using, so to make sure it fits properly. You should also make sure it fits in any other cars you plan to use it in.

    Some manufacturer’s website will list what cars their seats are expected to fit in, so it’s worth checking before you make a purchase.

    LATCH (Lower Anchors and Tethers for Сhildren) is a standard system of fitting which is installed in the most new family cars. It basically means that you can fit the child car seat without using a seat belt. LATCH is called ISOFIX in Europe.

    These seats have two or three points that can be fixed. There are two at the base and a third either as a strap to go over the back of the car seat or a drop-down foot. We recommend looking for one with three points as it’s generally more secure if fitted correctly.

    According to experts, the middle seat of the back row is safest because it keeps your child away from outer doors in case of a side impact. Stats show that the center position can reduce injury by more than 40% compared to installing the seat on one of the sides.

    There’s usually a gap between the two front seats allowing for easy installation. But, not all cars offer LATCH connectors which means you’ll need a seat belt for installation. Either way, the seat belt often becomes your only installation option after your child reaches a certain weight.

    How long is it before a convertible car seat expires?
    Most convertible car seats are good for at least six years from the date of manufacture. Most manufacturers put an expiration date statement into the bottom or back of a car seat, but if you can’t find it anywhere on the seat, check the owner’s manual or simply call to ask them.

    Can I use a Convertible Car Seat for my Newborn?
    Yes, you can but make sure the seat is rear facing. Babies’ heads are about a third of their body weight and their neck muscles are weak, so if they’re forward facing, there is a risk of the head being pulled by the force of the crash causing severe neck and spine injuries.

    When is my child ready for a Booster Seat?
    A child who has outgrown the weight or height limit of their forward-facing harnesses is ready for a booster seat. Typically, these are four to eight years old children ranging from 40-80 pounds or at least 35” tall.

    What if I am transporting more than one child?
    If you already have child car seats, make sure you take them along to the fitting so that you can check the new one will fit alongside them. Or, if you can’t take them with you, at least mention it to the retailer.

    Is it safe to buy a Second-hand car seat?
    We’d never recommend buying a child car seat second-hand or buying unofficial replacement parts. It may have been weakened by an accident or have wear and tear that could make it less safe for your child. Even if you’re using one from a friend or family member, it may have damage that you can’t see.
