Similarities

You can use the Diono Radian 3RXT and Clek Foonf rear-facing and forward-facing. The common feature they share is their maximum forward-facing weight limit of 65 pounds.


Differences


Rear-Facing.

Minimum Weight. The obvious winner between the two for this condition is the Radian 3RXT. Out of the box, you already have infant body support to use for the baby while we can only use Clek Foonf for the same child only if you spend additional money on separately sold infant thingy.*

Without the Clek infant thingy, Foonf could originally be used starting from when the child is about 3 months old.


Maximum Weight. Both seats are great for extended rear-facing use, but the country where they will be used will determine which product is better.

If you will use these products in the US, Foonf will be the champ because it has higher rear-facing weight limit of 50 pounds while 3RXT has 45 pounds. If you will use them in Canada, 3RXT will outshine the Foonf.


Maximum Height. There is only an inch of difference between these two’s rear-facing height capacity: 3RXT at 44 inches vs Foonf at 43 inches.


Forward Facing.

Maximum Height. Radian 3RXT can provide more room for the growing child as it can accommodate up to 57 inches while you can only use the Foonf up to 49 inches.


Booster. Between the two, only the Radian 3RXT can be used in booster mode, so you may think this will provide you with better value for the money.

However, many parent reviewers of this product expressed their disappointment with this product’s failure as a booster seat.

There seems to be no issue for children with a smaller stature, but not for taller and lankier kids.

Parents claim that getting a convertible car seat that promises usage until booster mode could be a gamble because there is no way to tell how much the child would grow in a few years.

Differences

The difference in these two seats’ dimensions might only become clear if you are installing them in a tight and compact vehicle where every inch of space matters.

If you are to place them in mid-sized vehicles, both can be good options for 3-across installation since they are narrow car seats.

**If the Foonf will be installed with the seat belt + Rigid LATCH, you can disregard the Rigid LATCH weight limit.


Similarities

Both may be installed with LATCH or with a vehicle seatbelt. They also both involve a base attachment for rear-facing installation.


Differences

Pool Noodle/Rolled Towel. Diono does not allow the use of aftermarket products when installing the Radian 3RXT.

Meanwhile, in the manual of Foonf and in Clek site's support article, it is written that you may place a pool noodle or rolled towel under the foot end if the acceptable recline level is not attainable.


Recline/Rear-Facing Base Attachment. The base accessory for each of these child restraints aid in achieving desired recline. You could see below more about the base attachments.

Ultimately, the Clek Foonf is a much better option when it comes to recline since it offers three different recline positions compared to the single internal fixed recline angle of Radian 3RXT.

This fixed recline is not an appealing choice for parents who were more familiar with the adjustable recline mechanisms that the Foonf and other convertible car seats have.

With this setup, the type of seat that your vehicle has will be the determining factor on how upright or how reclined 3RXT can be installed. For sloped vehicle seats, the 3RXT would end up more upright.

In vehicle seat with a raised bight, it will be more reclined.

Radian 3RXT has a color-coded detachable base attachment that must be placed under the car seat before installing it in the rear-facing.

When attaching this to the base of the Radian 3RXT, you need to make sure that the color-coded dots are aligned.

The Foonf’s detachable rear-facing base, although not equipped with color-coded dots, can provide 3 mechanical recline positions.

You can use positions 2 and 3 for rear-facing when in the US but only position 3 is to be used for rear-facing in Canada.


LATCH. 

Diono Radian 3RXT and other car seats (including the smaller and less expensive version of Foonf, the Fllo) are generally designed with the flexible strap/connector type of LATCH.

These car seats can be installed either with the LATCH or with the vehicle seat belts and not with both.

The Foonf offers the unique Rigid Latch that can make it a better choice than 3RXT. It should be noted that Rigid LATCH is only for forward-facing. Rigid LATCH is a steel component that is built into the base of Foonf.

The presence of Rigid LATCH in Foonf makes it a more beneficial option in different ways.

First, Rigid LATCH offers a much easier installation because it only requires the sliding of the connectors into the vehicle’s lower anchor connectors.

Second, it provides an extra measure of safety compared to the flexible LATCH. Connecting a metal component to the metal part of the car is like making the child seat an extension of the vehicle.

This may prevent the car seat from rotating if a side-impact collision occurs. The crash forces would be effectively channeled down to the Rigid-latch Energy Absorbing Crumple Technology aluminum center at the Foonf’s base.

Therefore, the probability of injuries to happen to the child will lessen.

Third, you could forget about the lower anchor or LATCH weight limit if you install this child restraint using the Rigid LATCH and the vehicle seatbelt. The keyword here is the “and.”

As mentioned earlier, the flexible LATCH of car seats only allows one method of installation. You can use the Rigid LATCH along with the vehicle seatbelt if you wish to forget about the forward-facing weight limits for lower anchors.

The problem with Rigid LATCH is that its advantages will be null if the seat location you want to install the Foonf on, such as the middle back seat, has no lower anchor connectors.


Lower Anchor Weight Limit. Parents often prefer installation using the LATCH because it is supposedly easier compared to installation using the vehicle seatbelt.

However, lower anchors have weight limits you need to pay attention to so that your child would remain safely seated on his/her car seat.

3RXT has lower anchor weight limits of 35 pounds rear-facing and 40 pounds forward-facing while Foonf has 25 pounds rear-facing and 35 pounds forward-facing.

This means that if installed with lower anchors, you can use 3RXT longer than the Foonf. The exemption is if you install the Foonf with Rigid LATCH and vehicle seatbelt in the forward-facing.

Similarities

Both have steel frames and 5-point harness, are side-impact tested and approved for airplane use.


Differences

Real Life Accidents. If you want a car seat that has more testimonials about how they were effective during car crash incidents, then 3RXT is your child restraint product to choose.

You can find many reviews on Amazon where the parents recounted how their children survived with no or at least minor injuries after an accident.

Looking for similar stories about Foonf, you will find this single recount on Facebook (at least as of writing this review), about an injured father and the miraculously uninjured 3-year-old son.  


Published Crash Test Results. Clek Foonf is the right choice if you want a product whose crash test results have long (and always) been available on the manufacturer’s website.

In fact, Clek has been approved by many parents who favor such transparency from car seat manufacturers. Foonf’s crash test results can be found on their site.


Rebound Reduction in Rear-Facing. A rear-facing car seat would move backward after the first impact. This area of concern could lead you in choosing Foonf over 3RXT because of the visibly present Anti-Rebound Bar or ARB.

3RXT also has a solution to reduce this rebound motion, but only if you could set up the rear-tethering in your vehicle.

You can reduce rebound motion in a rear-facing installed 3RXT if it is top-tethered.

This feature of 3RXT is often disregarded since many parents and caregivers tend to just skim through the user manual and skip the part where they could learn that top tethering can be done if the vehicle allows it.

If uncertain if your vehicle has the feature for rear-facing top-tethering, consult your vehicle manual (airbag section) or call your car manufacturer.

Vehicle manufacturers that do not allow rear-tethering in any of their car models include Dodge, Jeep, and Chrysler.

Prior to the installation of the Foonf, you need to add ARB. This ARB is to be placed at the foot of the car seat so it can add stability to the child restraint in rear-end/front-end collision.

What makes ARB more preferable than top-tethering is that it eliminates the need to check if the vehicle would allow rear-tethering.

And, you would already be given an idea that there is an ARB you should read about from the manual, since you can immediately see it when you unbox the package.


Unique Safety Feature. For their unique safety features, Clek could be the prime choice because it is already present and built-in as compared to the safety feature of 3RXT that would not work unless you install it.

3RXT has a "Safe Stop" component that would seem like a piece of an additional strap. Its yellow label should tell you it is not an ordinary strap.

To make use of this safety feature, you must attach it to the harness if we will use the child restraint forward-facing with kids below 40 pounds.

This load limiting device, if installed, can help reduce the impact and injuries to the chest, neck, and head of a smaller child in an accident.

Foonf’s REACT (Rigid-latch Energy Absorbing Crumple Technology) system is already integrated at the base of the car seat. If installed with Rigid LATCH, it will automatically perform as designed in a crash.

In the event of an accident, they design the green pin to break to allow the car seat to ride down the track. It will push the car seat down its aluminum crumple zone so that the zone will absorb the crash impact.


Traveling. If you want to take the car seat when traveling, 3RXT is a better choice since it can be folded for more convenient storage and carrying.


Post-Accident. After the car seats have been involved or damaged in a car accident, they ought to be replaced. Diono offers a more favorable post-accident option than Clek.

Diono has this "Voluntary Car Seat Warranty Exchange Program" wherein a set of criteria must be met in order for the car seat in question to be deemed eligible for a free replacement from Diono.

Clek, on the other hand, only offers a recycling program for damaged car seats.

Similarities

Both have breathable covers, ample space for the sitting child, shoulder harness pads and crotch strap pads.

Considering their price, it would be disappointing that these seats have no no-rethread harness system. Many parents today prefer a no-rethread harness because it is convenient and time-saving.


Differences

Seat Weight. 3RXT is lighter than the Foonf, but it is still considerably heavy. Foonf’s substantial weight is due to its Rigid Latch system.


Cover. Both car seats have removable covers. Yet, each of these covers entails specific removal and cleaning.

The 3RXT will not eat up your time and will not stress you further when it comes to cleaning and maintenance because the procedure is much simpler than that of Foonf.

You might come to appreciate the Foonf cover’s ability to resist stains and dirt because it has Clek’s Crypton’s C-Zero+ performance fabrics. However, Foonf’s cover, in worst-case scenarios, can only be hand-washed.

conclusion


The Clek Foonf and the Diono Radian 3RXT are approximately USD 170 away from each other. The Diono Radian 3RXT is cheaper.

These two car seats are among the more expensive car seats that promise to give more advanced features. You may consider each of these seats’ features to pick one that is most suitable for your needs.

Enumerating the best features of each product, you will see that Diono Radian 3RXT is what you may purchase if you like a car seat that

  • has a 1-inch additional rear-facing height limit
  • has an 8-inches additional forward-facing height limit
  • can be used until the booster mode (up to 120 pounds)
  • does not allow the use of pool noodles/rolled towels (helpful if you do not feel comfortable relying on such aftermarket products to prop up a reclined child restraint)
  • has higher lower anchor weight limits (strap LATCH connectors)
  • has a harness system that is easier to buckle and unbuckle
  • can be folded for more convenient storage and transport
  • is relatively “lighter”
  • if damaged in an accident, could be eligible for a free replacement if it passes the criteria implemented in Diono’s Crash Exchange Program
  • is more convenient to remove and wash the seat cover
  • already comes with infant support inserts and cup holder
  • has a longer expiration date
  • more crotch strap positions

  • is easier to install in all modes
  • has an adjustable recline
  • has a Rigid LATCH for easier installation and better safety
  • has a more obvious rear-facing rebound reduction mechanism, its anti-rebound bar (ARB)
  • has crash test results published on the manufacturer’s website
  • more harness heights
