The Clek Olli Backless Booster Seat is the best lightweight, portable booster for children ages 4–12 who need proper belt fit without sacrificing style, portability, or comfort. This belt-positioning backless booster solves the problem of adult seat belts fitting too high on smaller riders by raising your child 10 cm (4 inches) for a safer shoulder and lap belt position—while giving kids a cool, comfy seat they'll be happy to use every day and on trips. Weighing just 5 lbs with a carrying strap and Rigid-LATCH connectors that lock securely for added stability, the Olli is the ideal solution for multi-car families, frequent travelers, and parents who need ultimate portability. Compare the Clek Olli to the WAYB Pico Portable Booster: both weigh under 6 lbs and feature LATCH installation, but the Olli includes Comfort-Cube padding (no numb-bum design) and a dishwasher-safe cup holder, while WAYB Pico prioritizes ultra-minimal weight. Choose Olli if you want maximum comfort and portability with premium padding; choose WAYB Pico if you prioritize absolute lightweight minimalism. The award-winning Olli features Comfort-Cube construction with an extra layer of padding for long-term comfort, flame-retardant-free fabrics, and a strap-thingy carrying strap for hassle-free portability. Built for both parents and children who demand style, the Clek Olli is an award-winning booster seat featuring Rigid-LATCH (UAS) connectors that lock the seat securely into place in about 10 seconds for added stability and simplify daily use. The Comfort-Cube construction provides an extra layer of padding that protects against numb-bum on long drives and commutes. The lightweight design, weighing just 5 lbs, makes it easy for both parents and children to carry between vehicles, through airports, or around the city. A quick-release strap lets kids or caregivers remove the Olli quickly when it's time to go. The detachable, dishwasher-safe cup holder mounts on the right side for convenient drink storage and goes straight into the dishwasher for fast cleanup. An audible "click" confirms Rigid-LATCH engagement; the booster remains securely connected even when unoccupied. The Olli is also designed to meet or exceed all federal safety standards (FMVSS 213), backed by a lifetime extended warranty with a 9-year expiration, and its flame-retardant-free fabrics provide an eco-friendly, non-toxic alternative to traditional booster seats. Removable seat cover comes off for easy cleaning to keep the seat looking fresh. Designed with end-of-life recycling in mind through Clek's recycling program.
