Buyer’s Guide

I love to over-deliver in my articles. I’ve thought about what I could give that will help you the most. Since I’m already reviewing a ton of car seats, why not share with you my system? So I will give you my buyer’s guide.

This will save you a lot of time in the future. By using it, you will be able to eliminate car seats that are not the right fit and only spend time on those that work for you.

Before we can get to that, though. Here are a few important points to remember. First of all, the place where you put the car seat is important. Since you have twins, the typical rule doesn’t apply. I usually recommend using the middle of the behind the driver as a backup. With your kids, you might need to use both of them.

The second point is also very important. There are so many car seats that are poorly installed in the US. This means that all those little ones are not getting the best protection possible.

Remember the good rule of thumb that the wiggle room should be less than an inch. If you want to be absolutely sure, then you can reach out to a licensed professional. Also, I’ve recently noticed that many sellers like Amazon are offering car seat install as a service for a fee.

Let’s start the buyer’s guide.


This is the most important item on my list. All parents are interested in the safety features. Now let’s see what these car seats have for us. All car seats are indeed safe in the marketplace. There’s a big difference between the protections they offer.

Some have bare bone options, while others have a huge array of options. My best recommendation is to get the best protection you can afford.

Size Limits

This is my secret place where I can save money. Best of all, there’s no compromising on safety. As these car seats are expensive and you have to upgrade frequently, there’s one secret on how to save money.

It’s quite simple actually, all you have to do is plan ahead. Buy a multiple-function car seat. Or get an all-in-one car seat.


The installation has been a problem ever since car seats have been invented. Lately, brands have tried their best to get the simplest mounting as possible.

Typically the latch install is the fastest and most effective. Now that usually tapes out around the 65-pound mark.


Since we’re talking about kids, we all know that they will make a mess. Not only that, but we have to clean up after them. This is why I’ve only picked a car seat which is easy to clean.

This would be my buyer’s guide. If you like, it put it to good use.
