With the LUMN™ car seat, Nuna® has created an option that keeps up with kids' growth spurts—and burgeoning sense of style. The seat starts out as a harness design for toddlers, with multiple headrest and seating positions, along with an all-steel frame and EPP foam for next-level protection. As a booster, the seat continues to provide customized comfort, thanks to its 9 recline positions. The leatherette details and automotive-inspired sleekness of the design ensure big kids never feel like they're riding in a "baby seat," while parents will appreciate the machine-washable fabrics.Suitable for ages 2+ (30–65 lbs.) with harness, and 40–110 lbs. as booster seat.
