  • BUILT TO GROW — For extended use, the forward-facing MU1 Car Seat easily converts from 5-point harness for toddlers to belt-positioning booster for bigger kids.
  • HEAD AND TORSO PROTECTION — Superior DuoGuard with a deep rigid shell and EPS energy-absorbing foam for head and body support creates two levels of side-impact protection. A steel-reinforced frame provides additional impact protection for parent peace of mind.
  • EASY TO INSTALL — Premium LATCH connectors and LockSure belt-tightening system offer easy installation in either harness or seat belt mode while RideRight bubble levels and ReclineSure leveling system ensure a proper fit in the vehicle.
  • COMFORT FEATURES — The high back booster accommodates your growing child with a 9-position headrest and a 4-position recline. The extra deep, contoured ErgoBoost seat with dual-density foam padding offers a more comfortable ride in both modes.
  • SPACE-SAVING FEATURE — Two dishwasher-safe CupFolders with push-button removal fold away to save space when not use for a convenient travel booster seat.

MU1 Car Seat is designed to grow with your child from a toddler car seat to a big kid booster, easily transitioning from forward-facing 5-point harness to vehicle seat belt. Nine headrest positions accommodate growth throughout both modes and work together with a 4-position recline to support proper posture. An extra-deep ErgoBoost seat with dual-density foam padding is sloped and contoured for superior comfort.

DuoGuard provides two layers of protection with a rigid shell and EPS energy-absorbing foam that surround the head and torso. The seat shell is also reinforced with a steel frame for superior impact protection while remaining a slim car seat.

MU1 Car Seat is designed with smart functionality that makes it the easiest to install simply, accurately and securely—every time. A 4-position ReclineSure leveling system and RideRight bubble levels help achieve and verify a proper angle in the vehicle seat. Premium LATCH connectors and a LockSure belt-tightening system with wide routing make it easy to achieve a tight and secure fit with LATCH or the vehicle seat belt.

A padded, no-rethread harness with a one-pull tightener provides reassuring security for growing toddlers. The harness easily hides away to create a belt-positioning grow with me car seat with shoulder and lap belt guides for big kids four years and up. Two dishwasher-safe CupFolders feature easy push-button removal and fold out of the way to save space when not in use for a convenient travel car seat.
