Include the Clek Olli Backless Belt Positioning Booster Car Seat - Marshmallow C-Zero Plus


Olli is an award-winning belt-positioning backless booster. It says to your 6-12 year-old that it’s still cool to be safe in the car. Olli boosts your child’s height ensuring that the vehicle’s seat belt fits them just right while an additional layer of padding eliminates numb-bum syndrome. Easily transportable from vehicle to vehicle and especially handy while traveling from airport to rental car or even the taxi.

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 the 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

Numb-bum is what happens when you sit on hard surfaces for long periods of time — even your legs fall asleep!

The Olli is different: it’s built like the seat in your car. Clek's Comfort-cube construction includes an additional layer of padding that protects against numb-bum!

As world-class seat manufacturers, Clek wants to put an end to numb-bum.

The Comfort-cube is comprised of:

  1. Metal Substructure provides stability to keep your child in a comfortable and safe position
  2. Expanded polypropylene base delivers energy-absorbing capability to reduce the impact of those big bumps in the road
  3. Molded polyurethane foam pad maintains its comfy shape for years of cushy feel
Plush Fabrics: Soft and cozy seat cover fabric — perfect for your discerning young rider.
Fast & Easy Install: Clek LATCH connectors attach securely to your vehicle’s LATCH lower anchors in 10 seconds (or less) in most vehicles.
Quick Release System: Quick release system for easy removal.
Protective Fabric: Fabric on the underside protects your vehicle seats from scratches or snags.
Cup Holder: Detachable and dishwasher-safe.
Light Weight: Weighs 5 lbs. for easy portability between vehicles, through the airport or walking through the city.
Performance Fabrics: Crypton® Super Fabrics provide stain, moisture and bacteria resistance. The durable fabric is easy to clean while the seat cover is removable and machine washable.
Easy Portability: Strap-thingy carrying strap included with all Olli seats for no-hands carrying convenience. Slip the strap over your shoulder while moving from point A-to-B and beyond.

Great quality item - love clek!
June 10, 2021
I absolutely love the quality of clek items, and love the design. I did have one small challenge with getting the seat belt to buckle with this booster- due to the wideness. I had to buy a Seat belt extender to get it to work; otherwise it took some maneuvering and the kids were not able to buckle and unbuckle themselves without it.
By Jenni
Love it!

I bought this almost a year ago. It has been great for my large 10 year old son when other boosters were too small for him both in the weight limit and width. He now passes the 5 step test in one of our vehicles but chooses to still sit in his olli booster still because he thinks it is more comfortable than the vehicle seat! The fabric has been great. We have never needed to wash it and it still looks brand new. I love that it latches into the car to prevent it from becoming a projectile when my son is not sitting in it. The latch is also easy to disconnect which is super nice. My son loves the height of the arm rests.
  • Great padding
  • Great arm rests
  • Great fabric
  • Wish the back to to front measurement was deeper
Best UsesLarge, heavy kids that aren't tall enough to pass the 5 step test to sit without a booster. Long car rides

Great seat, and super easy to install/use. The height of the arm rests is just right, and it’s noce to have a booster that actually locks in.

My daughter who is turning 7 this year always complained about her old booster. Bought this for her and she loves it! She says “it’s much better mom. It’s comphy and I can buckle myself!” We have an older Volvo station wagon the latch works great in, it feels secure and fits great in our seat. It’s easy for the kids to buckle around the booster, unlike my daughter old seat. Also love we were able to match with car seat for our baby whose coming at the end of November.

We started with the clek foonf and now are girls have moved into the booster. I love the fact that these seats have the rigid latch system. We went on vacation and were in the car for 6+ hours with no complaints about sore bottoms. The loop to remove it is super easy my 7-year-old can take care of it with no problem.

Feels cheap, and won't fit in my cars...
August 10, 2018
The rigid latch won't install in my 2012 outback, 2016 Yukon, 2017 CRV, or 2018 Nissan Armada.
My kids disliked the hard plastic armrests. We went with the Chicco booster instead. The Chicco is just as soft to sit on, and is made better in my opinion. It's also a fraction of the cost.
  • Won't install-rigid hatch too specific for many different makes and models
  • Hard plastic arm rests
  • No washable cover

Our first backless booster didn’t have latch,; I feel so much safer having this latch to alieve my worry of my child shifting around & falling off the seat. Even grandpa can install this safely!!!
  • Lightweight, easy to install
  • Some cars I have difficulty buckling in because of the width of this seat

Best booster ever
August 3, 2018
This booster seat is the best backless booster. We have tried several. The price tag is higher than a typical backless booster but let me tell u it’s so worth it. My daughter is in love with the unicorn fabric and her and her friends fight over this seat. The fabric is easy to clean with a wet wipe. I love the fact it clicks in to the latches easily and take out is a cinch. No more backless boosters flying around in the car when I hit the brakes and I’m without kiddos!!!!

This seat has served us well. It is a more mature looking booster so it helps my older yet smaller kids not feel awkward getting out of the car. It is supportive and the kids love it. Only reason it is not a 5 star seat is because the cup holder only fits on one side of the car.
  • Good looking
  • Cup holder can only be one side.

My 9 year old - who still needs a booster loved that she finally graduated from a full back booster (I am an overprotective mom). Loves the black color as our other butt booster is bright pink. She said she feels grown up. Love that is latches to my car!

January 10, 2018
My daughter seems to love this seat! We bought this in addition to the Clek Oobr to keep in her grandmother's car. She says it's comfy, although I'm not sure how comfortable it will be for longer rides (I think the Oobr might be better for that). The installation is super easy, it feels solid and not at all flimsy. I purchased this brand because of the high safety ratings, and so far I have been very pleased with their products.
  • Safety ratings
  • Easy to use
  • Solid construction
  • Beautiful colors
  • Quality material
  • Might not be very comfortable for long rides

Best Booster Seat Ever!!
April 21, 2017
My 4 year old son loves this seat it makes him higher than other booster seats and he's more comfortable sitting on it also Looks and feels awesome the leather one (cooper). It's worth paying a little bit more for the leather one if you like to keep the aesthetic beauty of your vehicle's leather interior. The only thing I wish they could've done better making the seat is where the cup holder goes or attaches is limited to 1 cup holder and it's on the left side... they should've made it where it can be attached to either side so buyers have the option to switch cupholder sides or have 2 cup holders on both sides. For reference I got this olli in black cooper and it fits perfect in Audi Q5 and Q7 :-)
  • Latch system, Easy to use, stylish and modern
  • Cup holder placement limited to one side and one cup holder

February 11, 2016
Purchased for 6 year-old daughter of average height and weight for age. Perfect fit for Audi Q5. (Not so much for my wife's car (Mercedes CLA 250), where it leaves about a 2 to 3 inch gap from the back edge of the booster cushion and the seat, due to the fixed LATCH hooks and forward position of the latch attachments in that car).

Hope seat stays around!
September 17, 2015
Hope this seat stays around for my second grandchild. I bought several seats and went from store to store looking for a booster seat that would fit in my car without digging under the seat for the seat belt!! This is a perfectly sized seat. Thin enough to sit properly in the car to even my granddaughter can buckle herself in. Amen!
  • very easy to remove. One pull and seat is disengaged and the back seat of the car can easily be used.

Best booster ever
March 9, 2015
My daughter loves this seat. Since it's pink, comfortable and a "big girl chair", she loves hopping into it and buckling her seat belt. Since it has the latch system I love it! This is actually the second one we have purchased. When my husband got the new work truck that she was allowed in, this seat was the only one we considered. I highly recommend the Clek Olli booster seat and Albee Baby.

This booster seat is perfect. It has a great look with all the names of great cities and countries like Paris, Japan.......It is well made and very comfortable. It has a cool look about it so the 5 year old doesn't feel like she is in a baby seat.It latches in so there are no worries about stability and safety.

Great Booster Seat
December 17, 2012
I bought this as a replacement for a seat that my son outgrew. He loves it and so do I. It is a snap to get in and out of the car. Also, the construction and materials are high quality. My son says it is very comfortable. If you are looking for a great booster, buy this one.

Perfect Next Option
December 17, 2012
This is perfect for us with shorter older kids. Stays securely in seat, comfy, and wide enough. Only down side is that the new cup holder is only able to be installed on the right side. This doesn't work for us as the seat is positioned against the right side of the vehicle. This booster will help our 9 year old stay safe till he meets the guidelines for a regular seat beat to fit him probably without the stigma of being in a big booster seat. Plus the convenience of being able to quickly and easily changed to a different car/spot.

Clek Booster Seat
November 26, 2012
I think I like it more than my son does.
  • I like the LATCH system, it secures the booster into position. Quick one-handed attachment and release.
  • Breathable fabric + ample padding = comfort for child.
  • 1) Some bloggers have negative comments on the LATCH system for "forward facing" car seats. (The comments are taken out of context and do not apply to booster seats)
  • 2) The arm rests are fixed and do not fold up to facilitate loading and unloading the child.
