Say goodbye to eye rolls and the 'too old for this' debate. Say hello to a seat that finally speaks their language. The LUMN is a combination seat that matches their big kid style, keeping up with all their growth spurts and bringing the coolness factor.

With multiple headrest and recline positions when tethered, this forward-facing harness car seat transforms to a belt-positioning booster to deliver customized comfort for your child and a tailored fit for your car. Sleek automotive-style leatherette accents create a big kid appeal built to withstand the day-to-day of childhood. It's conveniently wipeable, and the seat pad is machine-washable, making cleanup a breeze. 

The LUMN takes them from little kid to bigger kid with a backseat glow-up to see them through all the milestones–with extra points for style.
