Vehicle Shopping with Car Seat Goggles

Just like buying a new car seat, buying a new vehicle can be very overwhelming. It’s hard to sift through all the information out there and to decide what should be a priority for your family.  While shopping many people consider paint colour, fuel mileage, safety ratings, and built-in entertainment and navigation systems, but surprisingly few seem to consider functional seating capacity.  If your family does or will include children it’s important to think long term about how the vehicle will accommodate car and booster seats as your children grow. There are a startling number of factors to consider from this perspective.

We have included a photo gallery to illustrate some of the more challenging vehicle design features that may impede a successful car or booster seat install, but first some details.  But don’t be alarmed!  Chances are you will find something that works with a particular vehicle, but your options might be limited.  Consider each feature carefully and decide what matters overall to you.  Would you like help narrowing down the options?  The knowledgeable folks at (from whom we’ve learned, and continue to learn a great deal), particularly in the Car and Vehicle sub-forum, can probably save you time and aggravation if you post the particulars of your situation.

How many people do you regularly transport?

Do you often have family visit and/or transport friends?

How old are the people you transport most often?

How long do you expect to own this vehicle?

How old will your children be at that time and what type of seats would they be in (rear-facing, forward-facing, booster)?

Do you plan on having more children in the future?

Tether anchors

How many forward-facing children do you have or expect to have at one time? If the vehicle is older than 2002, has it been retrofitted with anchors if possible? If not, is the retrofit part still available or easy to find? If it’s a 3-row vehicle be aware that many have only one tether anchor in the 3rd row, and sometimes none at all.  With few exceptions vehicles that come factory-equipped with tether anchors can not have additional ones added.  Do not use a “universal” unregulated/untested tether anchor or get into “do it yourself” mode when it comes to this critical safety element.  Contact a tech for a list of vehicles with more than three factory-equipped tether anchors if you anticipate needing the flexibility that multiple tether anchors offers.

Seat Belts

The type of seat belt present (lap belt or lap/shoulder belt), their locations, the length of the buckle stalk, whether the buckle is fixed and forward-leaning, whether the buckle sits forward of the bight (seat crease), and how the belt itself locks can all influence how and whether a car seat or booster seat can be installed in that location.  Some types of belts are straight out incompatible with car and booster seats, and other new types, such as Ford’s inflatable belts, may not yet be fully tested or approved with some models of car or booster seats.


More accurately called ‘head restraints’ they serve an important function in protecting an adult’s head and neck against whiplash-type injuries.  They are sometimes required to support a high back booster seat, always required for use with a backless booster seat, and often interfere with the installation of a forward-facing car seat.  Whether head restraints are adjustable, removable, or fixed and forward-leaning can very much affect what car or booster seats can be used there.


When shopping for a new or used vehicle it’s worth the time to investigate any available information on safety ratings, such as those published by the Insurance Institute for Highway Safety.  If purchasing an older vehicle investigate whether the seat belts are in good working order, or have ever been replaced (recommended after a vehicle is around 20-25 years old), and that existing safety features are undamaged and accounted for, such as airbags and tether anchors.

Seating Capacity

Many vehicles advertise themselves — or consumers assume — that seven seat belts means the ability to simultaneously transport seven people.  While that is possible given the absolute right combination of people it’s not usually as easy as it looks.  The same goes for many five-seaters that can’t actually seat five at the same time.  The Car Seat Lady made a handy pictorial showing three types of seating configuration to watch for in a back seat.  Essentially you want to avoid having seating positions cross over one another, or the middle be too narrow to accept a car or booster seat.  Take careful note of any restrictions in three-row vehicles. Sometimes it’s not permitted to install any seat in the 3rd row if it’s especially small or what’s considered ‘stadium seating.’  Get that car dealer to dig out the manual for you to read carefully!

Try Before You Buy

Already own seats, and you’re convinced you want to continue using them? Take them with you and try them out.  Install with UAS and then re-install with seat belt as eventually you’re going to max out the weight limit of the anchors and need to install with the belt.  Not fond of your seats? Research before hand what would be suitable for the vehicle you’re considering, whether you’re willing to budget that into your purchase price, and whether they will properly fit your child.


Trucks that do not have full-size cabs pose particular challenges due to their shallow back seats, access to tether anchors, and (in)ability to switch off the air bag in the front seat.  Extended cab trucks with flip down back seats are especially challenging; due to their depth and non-compressible materials very little will install there, and some manufacturers may prohibit installing a seat there.  No car or booster seat may be installed on a sideways facing ‘jump’ seat, nor a rear-facing vehicle seat.

So go forth and car shop – but look at the vehicle’s features with real, functional seating capacity in mind, armed with all of these helpful hints!
