The Nuna® EXEC next is a versatile, all-in-one convertible baby car seat for every stage: from the first ride home to the booster years. It easily converts from rear- and forward-facing seats to a belt-positioning booster designed for big kids. Slim enough to fit 3 across in most midsize vehicles, it's packed with smart safety features and designed for easy, no-stress installation. An all-steel frame, energy-absorbing foam and Nuna's Aeroflex side-impact system keep kids secure, while breathable, moisture-wicking fabrics, multiple recline options and a height-adjustable headrest keep them comfy. Luxe upgrades include stylish leatherette accents and spacious 3" cupholders.
