Our Review of the Clek Olli Booster Seat
Overview
Olli™ is Clek's™ award-winning belt-positioning backless booster seat designed and engineered to help keep your child safe. The portable booster seat that provides comfort and secure seating for modern families on the move.
Safety
The Clek LATCH system locks the booster seat into place quickly and easily using your vehicle's LATCH anchorage system.
LATCH (Lower Anchor and Tethers for Children) refers to the pair of fixed lower anchors built into the crease between the seat back and seat cushion. LATCH comes standard in some vehicles manufactured in 2001 and 2002 and all vehicles in 2003 and newer.
If your vehicle does not have a LATCH anchorage system, you can still use Olli unlatched.
Olli safety highlights
- Raises your child 4 in./10 cm. to improve in-vehicle shoulder belt fit
- Better positions the seat belt on your child's hips to improve safety
- Locks into place to provide additional booster seat stability in a collision
- Confirms that latches are locked with an audible "click"
- Provides a secure connection even when booster seat is not occupied
- Meets all Federal Motor Vehicle Safety Standards and Canadian Motor Vehicle Safety Standards
Comfort
Olli is built like the seat in your car. Our Comfort-cube™ construction includes an additional layer of padding that protects against numb-bum, which is what happens when you sit on hard surfaces for long periods of time – your legs fall asleep!

Clek Olli Booster Seat Reviews
Great Booster
Clek Olli Booster
A Must!
just bought a second one
Fantastic Seat!
Nice Seat
My only problem with the Clek Olli is that the rigid LATCH system does not work in all vehicles. Being "rigid" it is not adjustable at all - it is a permanent standard width. Unfortunately that means I cannot use this seat with the LATCH attached in my husbands' Honda Accord Hybrid. This is more of a reflection of a poorly designed LATCH system in the Honda than on the Clek booster seat. I believe Honda did this specifically because of the side impact airbags. The Honda design team located their lower anchors towards the middle of the two outer seats. You cannot put a seat with ridgid (non ajustable) LATCH in the middle seat. Also the seat belt is located between the two lower anchors for each outer seat, so you cannot attach a belt positioning booster with LATCH and use the vehicle seat belt. I could use the seat without attaching the lower anchors, but that was a feature I really wanted, and it seems to be something the Honda design team was trying to avoid, probably for safety. The Clek Olli works perfectly in my Jeep which is designed better. I could also fit 3 Cleks across the back of my Liberty if I needed to do that. My younger son is very small for 5, and still needs a harness booster seat, so we aren't ready for another Olli yet, but it would allow me to safely transport an extra friend.
As always, my order was placed easily and my seats arrived quickly. EliteCarSeats.com service was impeccable.
Awesome Olli!
Perfect!
I've tried them all...this is the best!
