Buyer’s Guide for the Best 5 point Harness Seats

It was a long and interesting article to write. I hope you’ve got a lot of value out of it. I thought that I would over-deliver and include a buyer’s guide.

Maybe shortly you will have to research a new car seat so it will come handy. Before we could get to it, though, here are a few things to keep in mind.

Not all spots for the car seats are created equally. The safest place to put your child is in the middle. I know that’s not doable for everyone, so here’s the second-best option which is behind the driver.

Installation is crucial. Since poor mounting won’t provide the necessary protection, then the car seat loses its purpose.

There indeed are few notoriously hard to install a car seat. Either way, it’s super important to check out the manual, and if you’re stuck, there are a bunch of videos online. Also if you have second thoughts, reach out to a licensed professional for help.

Amazon started offering car seat installs for a fee. Maybe that will work better for you. No matter which choice you go with getting the tightest install possible.

Let’s get this buyer’s guide started.


Safety is top of my list. This is the reason why we’re getting car seats to have our little one safe no matter what. My best advice in this category is to get the most protection that you can afford. There’s no such thing as an overprotected child when it comes to seats.

All car seats have the front and rear impact protection as standard. You can go a step beyond this. Side impact protection is becoming popular nowadays. It ranges from one up to three layers of protection.

A handful of pioneer models have rollover protection. As you know, these accidents are only a dime a dozen, but they are the deadliest ones.

Size Limits

Do you want to know how to save money without compromising safety? It’s so simple anybody can do it. Best of all, you don’t have to stay up until the crack dawn refreshing the page, hoping for a discount.

The secret is to buy a seat for many years to come. It’s that simple, the more it’s being used, the more money you’re saving.


In the early days, the installation was quite difficult. Now there is much advancement, so it’s getting easier and easier.

Make sure that the wiggle room is less than an inch.

Keep in mind that harness seats usually tap out around the 65-pound mark after that the seat belt is the next best option.


We’re talking about kids so that messes will be all too common. This is why it’s good to know ahead of time what you’re getting into. Stick with brands which have an easy removal and machine washable covers. If not, you will be in a world of pain.
