The features of the Clek Foonf are impressive, but the price can be a turnoff. Why is it called the “mother of all car seats?” Let’s find out.

Rear-Facing Weight:14 to 50 pounds, able to sit upright on their own*
Rear-Facing Height Limit:25 to 43 inches

*It could accommodate a newborn infant weighing 5 pounds and is 19 inches long with the separately sold infant-thingy.*

Clek Foonf can be used in two modes: rear-facing and forward-facing 5-point harnessed.

This rear-facing mode should be used until the child’s weight is 50 pounds; the child’s height is 43 inches and can already sit upright without help.

The forward-facing mode of Clek Foonf accommodates a child at least one year of age (although the recommended age is 2 years old), 22 to 65 pounds in weight, and 30-49 inches in height.

To place your children appropriately inside the vehicle you already own is a plus. Thus, the dimensions of the Clek Foonf is among the things that matter apart from its safety features.

Its widest point is 16.9 inches. This 3-across car seat may look bulky, but it can be slim enough to sit three kids across the back seat safely and comfortably in most car models.

Here’s An Overview of the Clek Foonf



Do I need to use a pool noodle/rolled towel?Yes, allowed as stated in the manual
Easy To Install Rear-Facing?Yes
Easy To Install Forward-Facing?Yes
Easy To Uninstall?Yes

When installing the Clek Foonf car seat, you must do the following as a preparation.

  1. Add the headrest
  2. Install the required (in the rear-facing mode) Anti-Rebound Bar (ARB)
  3. Attach the separate rear-facing base

The rear-facing base will allow you to control the recline. Just slide this wedge in the holes on the base of the car seat and lock it in place.

See the video on how you can easily do the above three steps.

Prepare the Clek Foonf for Installation

Once you are done with the above steps, you need to recline the seat all the way back.

The LATCH connector “straps” are under the seat bum area. You’ll need that for the rear-facing LATCH installation. Remember, the Anti-Rebound Bar is required in the rear-facing mode at all times.

Should your vehicle be the older model (cannot be used with LATCH), you can easily do a seat belt install. The visible belt path, and the belt tensioning lock-offs, are both made to ensure that it secure the seat in the rear-facing mode.

Clek Foonf’s seat belt install is great not only for older vehicles but especially if the seat will be transferred frequently from one car to another.

Here’s a video that can help.

How To Install The Clek Foonf Rear-Facing By Seat Belt And By LATCH

Clek Foonf is one of the few convertible car seats with a “rigid LATCH.” Remember the LATCH “straps” used in the rear-facing mode? That’s how the “usual” LATCH connectors look like for most car seats.

The “rigid LATCH” to be used in the Clek Foonf’s forward-facing mode looks different. It is already attached to the car seat. It needs to be connected to the vehicle’s anchor simultaneously. To do the process comfortably, you will need to push the seat across it, all the way to the front to give you some working space.

The rigid latch will make the seat securely installed with no need for you to do tightening efforts, as you would normally do with LATCH “straps.”

One way to see that you have safely installed the car seat in the forward-facing mode is when the rigid LATCH indicator is green.

For safety, you still must push and pull the car seat side-to-side and front to back to make sure it doesn’t move more than an inch. If it doesn’t, you have a safe install.

You can use a combination of rigid LATCH AND seat belt in the forward-facing mode.

The added tether installation varies from vehicle to a vehicle. Check the location of your vehicle’s tether anchor so you’ll know where to attach the tether strap.

The Clek Foonf car seat can be installed and uninstalled quickly.

See this video on how to perform a forward-facing install.

How To Install The Clek Foonf Forward-Facing With Seat Belt And LATCH



Country Of Origin:Canada
Steel Frame:Yes
Five-Point Harness?Yes
Side Impact Tested:Yes
Approved For Airplane Use:Yes
Easy To Buckle And Unbuckle?Relatively

The Clek Foonf car seat is tank-like in construction. They engineered its substructure with magnesium and steel.

The anti-rebound bar (ARB) offers additional security. The ARB is what can prevent frontal and rotational rebound during a side-impact collision. This feature allows the seat to be firmly nested and flat on the vehicle seat.

Foonf also has “crumple zones” for a revolutionary safety feature. This is said to absorb the energy occurring during a crash and protect the young passenger. Further absorbing the energy is the dual layer of “foam” in this car seat.

Most car seats have the “EPS” foam, which, according to them, has a tendency to break in a car crash.

The Clek Foonf has an “EPP" foam, which according to them, is sturdier.

Foonf is, NCAP tested, FAA certified and can be used in an airplane. It also complies with appropriate Federal Motor Vehicle Safety Standards.

On the downside, there are parents who say that the buckles can be stiff sometimes. Better pay attention to how you clean it as it can affect how easy or difficult you can use it.

Is The Material Breathable?Yes
Seat Weight:38 pounds with rear-facing base, 33 pounds without
Machine Washable Cover?No

The package of Foonf contains the Clek Foonf car seat, the ARB, the rear-facing base, and the owner’s manual.

You must do product registration online (within 3 months after purchase) and with this, it will extend the warranty of your purchased product for two years. Registration will help inform you about product updates.

The Foonf is like other car seats from Clek that can be recycled through the company’s recycling program.

Clek is known for its "Crypton (Super fabric)" seat. It has permanent protection against bacteria, moisture, and stains. These fabrics are free from chlorine, and bromine flame retardants.

They say the seat cover is stain-proof, but anything (dirty) can happen with children and toddlers.

Parents thought it is not washable, since Clek offers a fabric cleaning kit which can add up to the cost in the long run. But if you watch this video, you'll see that you can remove and hand-wash the seat cover.

Foonf has been updated in 2017 and the new version now has more padding and added protection for the crotch strap. If you bought Foonf prior to this 2017 update, you may buy the new padding from Clek instead.


How can the Clek Foonf be the “mother of all car seats?” Well honestly, it’s just their marketing slogan. But here’s my take for that:

If you look at all the car seats I have reviewed, most of them do not have the “rigid LATCH,” even the Clek Fllo which is from the same brand.

At least as of updating this review, their forward-facing modes use the “strap” LATCH which, depending on your experience with car seats, can be easy or “difficult” to tighten.

Clek Foonf Rigid Latch

With the Rigid LATCH of Clek Foonf, it is trying to say, “Hey, this is how it should be done!” Lol.

I’m just trying to make sense of their slogan. Because honestly, I don’t know what’s the reason behind it. Or maybe because of its “EPP” foam, which is better than the “EPS” foam (cheaper car seats have EPS foams).

Being a “mother of all car seats” also probably entails the Clek Foonf’s high points: the highly advanced safety features, sturdy construction, and streamlined appearance.

Car seats are not just meant as a device that will keep babies and children in their place while riding a car.

More than being a seat, they are also supposed to be the bubble wrap that will keep these young passengers safe - and Clek Foonf is certainly a “mother” in that aspect.

Honestly, I have been avoiding to review the Clek brand for long since I thought it was too overpriced. I thought my readers will not need it anymore since I already found "good convertible car seats" to recommend.

But I was wrong. I would really buy the Clek Foonf and pay little attention to its hefty price tag. For what it can deliver, you’ll have a second “mother” inside your car.

I highly suggest that you check out the feedbacks of parents who got this seat to help you decide further.

  1. I have been trying to decide what car seat to buy for my new grandchild and was so confused.  Your review of Clek Foonf car seat has convinced me that it is probably one of the best in the market.  I particularly like the padding around the straps as the car seat I use at the moment for my other grandchild is a problem without this.  My granddaughter gets chaffed between her legs because of a lack of padding and I have to use a small towel or something similar to make it comfortable for her.  I also like the stronger foam and added safety.  Thank you for making my choice easier.

    1. Hi Liz,

      Glad to have helped with your decision. Just make sure to use recommended/compatible strap pads* as replacements when you need new ones for this Clek seat. It is never advisable to just use any third party cushion on the straps, as these seats are only tested for safety using the default accessories it comes with.

      Kind Regards,

  2. Thank you for the in-depth review of the Clek Foonf.  I have to admit, there are so many options out there, it’s hard to really know what’s good and what isn’t.  Even more so, what features you don’t even know about that might be available on various models.

    I really appreciate the time you spent in putting this together.  Between what you’ve written here and the videos, I feel a lot better about making a decision. I have a newer model car so I should be good for the LATCH connection and it’s nice to know it’s good for flying too.

    In your opinion, is this one of the best seats out there (i.e. is this your top recommendation or is there another you think might edge this one out)?  After all, you do make reference to this being a second mother in the car.

    Thanks again,

    1. Hi Scott,

      I have reviewed and compared a lot of car seats, and yes, the Clek Foonf is one of the best out there. However, it is on the more expensive side. Here is a link of all the GOOD car seats based on my thorough research. There are links to comparisons of all the good car seats inside that article, too.

      I hope this helps.

      Kind Regards,
