Clek Olli Backless Booster Seat with Rigid-Latch System - Thunder

Our review of the Clek Olli Backless Booster Seat finds it best suited for families who want a compact, travel-friendly booster that still prioritizes safety. The single biggest reason to buy is the seat's RIGID-LATCH System, which keeps the booster firmly anchored during travel and even when unoccupied, reducing movement and improving peace of mind. Lightweight at about 5 lb., this booster balances portability with thoughtful features like extra padding, a quick-release strap, and a washable cover that make day-to-day use and cleaning straightforward.

Key Features

• RIGID-LATCH System: Provides a stable connection to the vehicle that minimizes seat movement and improves safety during collisions.
• 4 in. boost height: Raises a child to improve shoulder belt positioning for better restraint fit with most vehicle belts.
• Lightweight design: At roughly 5 lb., the booster is easy to move between vehicles and convenient for travel or carpooling.
• Quick-release strap and Strap-thingy: Quick-release strap speeds installation and the hands-free carrying strap makes transport effortless.
• Removable washable cover: C-Zero Plus Performance Fabric resists stains, moisture, and odor and removes for machine washing.
• Detachable cup holder: The Drink-thingy is washable and useful for drinks or small items on longer trips.

Who It's For

The Olli is aimed at caregivers of children who are ready for a belt-positioning booster and need something both safe and portable. It fits well for families who switch cars frequently, travel, or want a compact booster for older toddlers through preteens.

Those who need a high-back booster with head support or integrated harness for younger children should look elsewhere; this model is strictly a backless, belt-positioning booster intended for children meeting local age and size requirements.
