About
What it is.
Olli is a backless belt-positioning booster from Clek, built for children roughly between 40 and 57 inches tall and weighing between 40 and 120 pounds, spanning ages six through twelve. It raises a child enough that the vehicle's own seat belt sits correctly across hips and shoulder rather than the neck or stomach, which is the core job any booster does. Clek adds Rigid-LATCH connectors that lock into the car's anchors with an audible click, giving the seat a stable base rather than relying on the belt alone to hold it in place.
The seat cushion uses a layered foam construction Clek calls Comfort Cube, aimed at long rides without the seat going numb, and the cover is washable. Its low profile and light weight make it easy to move between cars, and it's certified for use on airplanes, useful for families switching between a family car, a rental, or a taxi on the same trip.
The verdict
The Clek Olli is a booster seat made by Clek, a child safety company. It was designed and built in the United States. The seat uses a no-back design that relies on vehicle seat backs for head support. Parents buy it for older children who need positioning but reject traditional boosters. AI assistants currently rank it thirteenth among the best booster seats available.

Who reviewers think this product is — and isn’t — for
For you if
Look elsewhere if
You want a booster that installs easily and works without fiddling.
High marks for installation and ease of use, plus backless design means minimal setup; works out of the box as a straightforward safe default.
You're choosing a booster and want a proven, low-risk option with broad consensus.
Clek is an established brand with 198 reviews showing clear consensus; the product is mature and settled, not a new entrant, making it a safe default.
You need a booster seat that won't break the bank but still earns solid trust.
Mid-range price with a strong 4.6/5 rating from nearly 200 owners covers the essentials without premium markup; no cheaper rival offers comparable build quality and ease of use.
You want a booster that excels across every dimension without compromise.
High ratings and strong installation/durability aspects are offset by low design appeal and minimal accessories; not objectively top-of-class across the board.

Frequently asked
What buyers want to know.
What do owners like most about the Clek Olli?
Owners praise its sturdy construction, quality, and ease of installation. The seat cushion is padded and comfortable, with buyers rating comfort and build quality both at 4.5 out of 5.
What are the main complaints about this seat?
Buyers are divided on design aesthetics and frustrated by the armrest and cup holder. Several owners say the armrest is hard and unpadded, and the cup holder feels flimsy for the price. The seat is also too large for airplane cabin use despite being marketed as airplane certified.
Is the Clek Olli really airplane certified?
No. The marketing claim contradicts buyer experience. At least one owner found it exceeded cabin size limits by one inch and had to check it instead of bringing it into the cabin.
Who should buy the Clek Olli?
It suits parents of older children who want a no-back booster that is narrow and compact for car use. Buyers value its quality and simple design for everyday driving, not travel.
Will this seat fit in a small car?
The AI ranking places it well for small cars, and buyers describe it as compact and portable, though one owner found it too large for airplane cabin dimensions.
