Comments
  • Narrow
  • Low profile makes it great for 3-across situations
  • High rear facing weight limit
  • Allows for tethering rear facing
  • Can be difficult to install
  • Often requires the angle adjuster to avoid taking up a large amount of front to back space
  • Booster mode isn’t very functional because of the 50 lb minimum and the short belt guides, it will be outgrown at the same time as the harness function.
  • Note: to get a good newborn fit, you will need the infant insert and the shorter harness straps (sold separately)
