Nuna LUMN Harness to Booster Car Seat

The Nuna LUMN Harness to Booster Car Seat grows with your child from 30 to 110 lbs and up to 57 inches, delivering serious safety and style throughout their "big kid" stage. An all-steel frame, Aeroflex side impact protection, 10 headrest and 9 recline positions when tethered keep bigger kids protected and comfortable on every ride.
