With their steel construction, innovative safety features and extended rear-facing use, the  Clek Foonf and Nuna RAVA often go head-to-head with parents seeking the safest and most stylish convertible car seat for their child.

To start, both seats have longest rear-facing weight capacity on the market: 50 pounds. But do you really have to make your kid ride backward for until her 4th birthday? You should: A study in the journal  Injury Prevention found that the risk of death in a crash is five times lower when children are rear-facing.

Let's start the Clek Foonf vs. Nuna RAVA debate by looking at each car seat. 


Clek Foonf

Founded by a former automotive industry executive, Clek makes car seats that mimic the safety and design of the seats in our vehicles. Upon its 2012 debut, the Canadian-made Clek Foonf revolutionized the market with features like crumple zone technology and an anti-rebound bar that minimize the impact of crash forces on your child. Watch the video below for an introduction to the Clek Foonf.



Nuna, a Dutch manufacturer of baby gear, made a strong entry into the convertible car seat market in 2016 when it introduced the RAVA. The seat combines top-of-the-line safety with innovative convenience features, like a no-rethread harness, machine-washable fabric and easy installation. Watch the video for an overview of the RAVA.




While both seats are priced at the top of the market, keep in mind that you'll use the convertible car seat much longer than you used your infant car seat. Both the Foonf and RAVA have a weight limit of 65 pounds, which will take kids to approximately age 6.

The Clek Foonf comes in two fabrics: plush fabric and the smoother woven fabric, which costs $20 more. All colors of the Nuna RAVA are the same price.

  • Clek Foonf (plush fabric): $449.99
  • Clek Foonf (woven fabric): $469.99
  • Nuna RAVA: $449.95

Product weight

  • Clek Foonf: 33 pounds
  • Nuna RAVA: 27.2 pounds

Rear-facing specifications

Because the Nuna RAVA contains an infant insert, it can be used for babies as small as 5 pounds. To ride in the Clek Foonf, babies must be 14 pounds or use Clek's Infant-Thingy insert, which accommodates babies weighing 5 to 22 pounds.

  • Clek Foonf: 14-50 pounds, 25-43" height
  • Nuna RAVA: 5-50 pounds, 49" or less height

Forward-facing specifications

Both seats have the nearly the same forward-facing specifications. Clek and Nuna recommend keeping your child in the safest, rear-facing position until at least age 2.

  • Clek Foonf: 22-65 pounds, 30-49" height
  • Nuna RAVA: 25-65 pounds, 49" or less height


  • Clek Foonf: 1 year
  • Nuna RAVA: 2 years


The Nuna RAVA comes in five colors: Slate Gray, Caviar Black, Berry Red, Blackberry Purple and Indigo Blue.

With the Clek Foonf, you can choose your fabric type (plush or woven) and, in some cases, a black or white base.

Plush fabric colors include:

  • Capri Blue (white or black base)
  • Dragonfly Green (white base) or Tank Green (black base)
  • Flaming Pink
  • Shadow Black
  • Ink Blue

Woven fabric colors include:

  • Thunder Gray (black base) or Cloud Gray (white base)
  • Slate Gray
  • Woodlands Green (black base) or Cadet Green (white base)


Safety Features

Clek Foonf

Clek is known for the unique safety system it calls REACT: Rigid-LATCH Energy Absorbing Crumple Technology. 

Using the same technology found in automotive seats, the Clek Foonf contains aluminum honeycomb, which crumples as it absorbs energy—resulting in less force reaching the child. The Rigid LATCH anchors are steel instead of the typical fabric, which provides a stronger connection to your vehicle's LATCH system and makes the seat easier to install in the forward-facing position.

Additional safety features on the Clek Foonf include an anti-rebound bar, which limits the ability of the seat to rotate when in rear-facing mode, further protecting the child's head and neck in a crash. The Foonf's headrest contains energy-absorbing foam and attaches to the frame with steel rods that also inhibit the headrest's movement.

Unlike other car seat manufacturers, Clek makes  crash testing information for its seats publicly available. Testing for head injury and chest acceleration criteria shows that the Clek Foonf is well under acceptable thresholds: For example, the head injury score for a 1-year-old in a Clek Foonf is 339—66 percent below the limit of 1,000.

Featuring an all-steel frame and energy-absorbing foam, the Nuna RAVA uses premium materials to keep your child safe. Although it lacks the REACT system and anti-rebound bar of the Clek Foonf, the RAVA offers one unique safety feature: side-impact protection pods that pop out of the seat frame to be the first line of defense in a collision. 

But perhaps the strongest argument for the Nuna RAVA's safety is its ease of use and installation, considering that the National Highway Traffic Safety Administration says that nearly three-quarters of car seats are used incorrectly. See how to install both seats in the next section.


Clek Foonf

Rear-facing: The Clek Foonf can be installed with the LATCH anchors until the child weighs 25 pounds—at which time the weight of the car seat and child combined is too heavy for your vehicle's LATCH system. To install the seat with LATCH, you'll remove the seat cushion to reveal the LATCH belt, thread the belt through the sides of the seat, and then snap the connectors onto the lower anchors.

After your child is 25 pounds, you'll install the Foonf with the seat belt, again by removing the seat cushion, threading the belt through the seat and fastening it.

In the rear-facing position, you'll also need to add a wedge-shaped base that allows the seat to recline, as well as install the anti-rebound bar onto the base.

Forward-facing: Installing the Foonf in a forward-facing position is simple, thanks to the rigid (metal) LATCH connectors that snap onto your vehicle's anchors.

See the Clek website for step-by-step videos on installing the Foonf.

Nuna RAVA 

Rear-facing: Although the Nuna RAVA can be installed rear-facing with the LATCH anchors until the child is 35 pounds, Nuna advocates that "belt is best" because it eliminates the confusion about when to switch to between LATCH and belt installation. Plus, the RAVA is among the easiest convertible car seats to install with the seat belt.

To install with the seat belt, you'll lift the seat padding to reveal Nuna's True Tension doors in the bottom of the seat. The two doors are color-coded to differentiate rear-facing and forward-facing installation instructions. Route the seat belt under the door and buckle the seat belt. Lock the shoulder belt, close the True Tension door, and the seat is installed.

Forward-facing: Installing the forward-facing RAVA involves a similar process, as well as attaching a tether cord to the back of the vehicle seat.

Harness Adjustments

The five-point harnesses on the Clek Foonf and Nuna RAVA are height-adjustable in different ways.

The Clek Foonf harness requires "re-threading," which involves opening the back of the seat to expose the harness slots. You'll detach the straps from a metal piece called the spinner plate, pull the straps in the front of the seat, and re-thread the straps through one of several slots in the fabric. Then re-attach the straps to the spinner plate.

The Nuna RAVA harness is quicker and easier to adjust, thanks to its "no-rethread" harness. Simply press a button in the front of the seat while pulling the straps and raising the headrest.


Comfort Features


When it comes to recline positions that keep your child safe and comfortable as she grows, the Nuna RAVA wins with 10 positions: five rear-facing and five forward-facing. To recline the seat, press a button on the side of the base and slide the seat. A numbered and colored indicator makes it easy to check whether the recline angle is safe for your child's age and position. If the child's head is falling forward, the seat should be further reclined.

The Clek Foonf features two forward-facing recline positions and two rear-facing recline positions. From the front of the seat, pull the recline lever to slide it into the desired position. Compare the recline to an angled line printed on the side of the base to ensure the Foonf is in a safe position for children older or younger than age 1.

Both seats feature a height-adjustable headrest. On the Clek Foonf, the headrest is connected to the frame using steel rods, just like the headrests in your vehicle—a feature that Clek says offers superior head protection in a side-impact crash.

Leg rest

The Nuna RAVA offers a comfort feature that the Clek Foonf does not: a leg rest that provides two additional inches of legroom, allowing for longer rear-facing use and for extra support when the child is facing forward. The Clek Foonf does not have a leg rest.

Cup holders

The Nuna RAVA features two built-in cup holders that fold away when not in use. For the Clek Foonf, the cup holder (" Drink-Thingy" in Clek speak) is sold separately for $19.99.


Fabrics and Cleaning

Featuring machine-washable fabrics, the Nuna RAVA is easier to clean than the Clek Foonf. The covers for the seat pad, head support and child restraint area can be removed, and along with the harness pads and infant insert, they're safe for the washing machine (though not for the dryer). 

The Clek Foonf seat cushion and seat back covers can also be removed, though the fabric's tighter fit on the seat frame makes doing so more difficult. The fabric isn't machine-washable, so spot cleaning with a mild detergent is recommended.

However, the Clek Foonf features advanced Crypton Super Fabrics that provide protection against stains, moisture and odor-causing bacteria. If you spill liquid on the Clek Foonf, you'll see it bead off. Plus, the fabrics are free of brominated and chlorinated flame retardants.


Pros and Cons
