Compare Clek Oobr and Olli booster seats: height limits, features, and fit. Find out which high-back booster suits your child's needs and your vehicle.
When your child outgrows a forward-facing harness seat, it's time to transition to a booster seat. Clek offers two popular high-back booster options: the Oobr and the Olli. Both are designed with safety and comfort in mind, but they have distinct features that may make one a better fit for your family. In this comparison, we'll break down the differences in height limits, installation, and adjustability to help you decide.
Whether you're shopping for a first booster or a second seat for a different car, understanding the nuances between the Oobr and Olli is key. We'll also touch on how Clek's accessories, like the drink-thingy, can enhance the booster experience for your child.
Overview of Clek Oobr and Olli
The Clek Oobr is a premium high-back booster that offers both high-back and backless modes. It's known for its rigid LATCH system, which anchors the seat to the vehicle for added stability. The Oobr also features a patented 'Cushion' technology that provides comfort during long rides. It accommodates children from 40 to 120 pounds and up to 62 inches tall.
The Clek Olli, on the other hand, is a simpler, more streamlined high-back booster. It also has a rigid LATCH system but lacks the backless mode of the Oobr. The Olli is designed for children from 40 to 100 pounds and up to 57 inches tall. It's a great choice for parents who want a dedicated high-back booster without the extra flexibility.
- Oobr: 40-120 lbs, up to 62 inches, high-back and backless modes
- Olli: 40-100 lbs, up to 57 inches, high-back only
Height Limits and Fit
One of the biggest differences between the Oobr and Olli is the height limit. The Oobr accommodates children up to 62 inches, while the Olli tops out at 57 inches. If your child is tall for their age, the Oobr will give you more mileage. Additionally, the Oobr's headrest adjusts higher, which is crucial for proper belt positioning as your child grows.
When it comes to seat width, both boosters are similar, but the Oobr offers a slightly wider seat, which can be more comfortable for larger children. The Olli is a bit more compact, making it easier to fit three across in many vehicles. Consider your vehicle's back seat space and your child's proportions when choosing.
- Measure your child's height and torso length before deciding.
- Test the booster in your car to ensure a good fit.
Installation and Safety Features
Both the Oobr and Olli feature Clek's rigid LATCH system, which locks the booster securely to the vehicle's anchors. This prevents the booster from sliding or tipping in a crash. Additionally, both seats have energy-absorbing foam and a steel frame for impact protection. The Oobr adds an adjustable headrest and side impact protection that can be raised to provide extra coverage for taller children.
The Olli is slightly lighter than the Oobr, making it easier to move between cars. However, both are relatively heavy compared to other boosters on the market. If you frequently switch vehicles, you might prefer the Olli's lighter weight. But if you want the highest level of side impact protection, the Oobr's adjustable headrest is a valuable feature.
- Always refer to your vehicle's manual for LATCH anchor locations.
- Check that the booster is tightly installed with no more than 1 inch of movement.
Comfort and Convenience Accessories
Both the Oobr and Olli are compatible with Clek's drink-thingy, a cup holder that attaches to the side of the seat. The drink-thingy for foonf and fllo is a popular accessory, but for boosters, you'll want the drink-thingy for olli. This handy accessory keeps drinks and snacks within easy reach, making road trips more enjoyable for your child.

If you're looking to protect the seat from spills and wear, consider the Ziip Fabric Cover Set for Foonf and Fllo. While designed for convertible seats, the same durable, easy-to-clean fabric is used in the Oobr and Olli, so you can expect similar quality. For extra comfort, you might also look into harness covers, though they are primarily for harnessed seats.
- The drink-thingy for olli attaches securely to the side of the booster.
- Clek's fabric covers are machine washable and made from non-toxic materials.
Price and Value
The Oobr is generally more expensive than the Olli, reflecting its higher height limit and additional features like the backless mode and adjustable headrest. If you have a tall child or plan to use the booster for many years, the Oobr may be a better investment. However, if your child is average height and you prefer a simpler, more affordable option, the Olli offers excellent value.
Both boosters are built to last, with high-quality materials and construction. Clek also offers replacement parts, such as the Foonf/Fllo Anti-Rebound Bar Locking Pins, but for boosters, you'll likely only need to replace fabric covers or the drink-thingy over time. Consider the long-term cost when making your decision.
- Compare prices online and check for sales.
- Factor in the cost of accessories like the drink-thingy.
In summary, the Clek Oobr and Olli are both excellent high-back boosters, but they cater to different needs. If you have a taller child or want the flexibility of a backless mode, the Oobr is the way to go. If you prefer a lighter, more affordable booster with a simpler design, the Olli is a great choice. Whichever you pick, you'll get a safe, durable seat from Clek. To see the Oobr and Olli in action, check out our product pages and find the perfect fit for your family.
