Diono Cambria LE Booster Seat

Pros

  • High-back and backless modes let the seat keep shoulder-belt guidance before moving to a simpler booster.
  • The six-position headrest and 96.5-160 cm/38-63 in range provide useful adjustment for a growing child.

Cons

  • A broad size range does not establish seating maturity; check the vehicle belt path and head support in both modes.

Diono Cambria LE makes sense for a child who has outgrown a harnessed seat and can remain correctly positioned for the whole ride. Its two-in-one design starts with high-back shoulder-belt guidance and a six-position headrest, then converts to backless only when the child and vehicle still provide the required fit and head support. The stated 18.1-54.4 kg/40-120 lb and 96.5-160 cm/38-63 in envelope is not a readiness guarantee. Trial it in the intended rear seat: the lap belt should stay low on the hips, the shoulder belt centred, and the belt should retract after movement without crossing the neck. Check the child’s ears remain supported, use a lap-and-shoulder belt only, and follow the delivered Canadian label/manual and vehicle manual for each mode and for securing an empty booster.
