ClickTight Installation System
Allows parents to easily achieve a safe and secure installation using the vehicle seat belt throughout the life of the seat, in harness mode, without having to worry about the weight of their child (May not be compatible with all vehicles. See installation instructions.)

Side Impact Cushion Technology
Features energy-absorbing cushions on the exterior of the child seat to reduce side impact crash energy by diverting crash forces before reaching your child and providing extra protection for the adjacent passenger

Base with SafeCell Technology
Designed to keep your child safe and secure in a crash by compressing and significantly lowering the center of gravity, reducing the forward movement of the car seat


  • True Side Impact Protection provides deep side walls and a head restraint with energy-absorbing EPP foam to distribute crash forces, shield from vehicle intrusion, and contain the head, neck and body while keeping them in true or aligned
  • Energy Absorbing Versa-Tether anchors the top of the car seat to the vehicle using a two-point attachment, minimizing the amount of forward movement of the car seat. Stage-released stitching helps reduce the crash forces reaching the child
  • EZ-Buckle System retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding
  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
  • Tangle-Free, Five-Point Harness (with 9 harness height positions -up to 20.5) distributes crash forces across the strongest parts of the body and provides a secure fit
  • Two Buckle Positions offer a snug and secure fit for your growing child
  • Armrests provide a natural and comfortable place to rest arms
  • Quick-Adjust No-Rethread Harness easily adjusts the harness shoulder height and head restraint from the front of the seat without disassembling the harness straps
  • Easy transition from Harness to Booster mode without removing harness straps
  • Integrated Cup Holders and Storage are designed for easy access to childrens cups, snacks and toys
  • 120 lb (54.4 kg) Weight Capacity in Booster Mode for safety and comfort as your child grows
  • 65 lb (29.5 kg) Weight Capacity in Harness Mode allows your child to remain harnessed up to 65 lbs (29.5 kg)
  • Easy-Remove Cover allows easy cleaning without disassembling the harness or uninstalling the car seat
  • Color-Coded Vehicle Belt Guides provide clear indication of the path and positioning of the vehicle seat belt for use in either harness or booster mode
  • Harness Ultra Guard System (HUGS) provides resistance to forward movement in the event of a crash
  • Compatible with SecureGuard which works with the vehicle safety belt in booster mode to prevent the child from sliding under the lap-belt portion of the safety belt during impact, thus minimizing the risk of abdominal injury (accessory sold separately)
