About the product

Overview

An infant carrier from German brand CYBEX that is always installed rear-facing and approved to UN R129/03 (i-Size) for children 40 to 87 cm tall and up to 13 kg. This listing is the Lava Grey colour, product code 523001147. The Base G is sold separately.

Key features

  • Strong independent test results: in the German ADAC test (May 2024) the seat alone scored 2.0 (good) overall and 1.5 for safety, with a very low injury risk in the frontal crash and a low risk in the side crash. With the Base G it scored 1.8 (good).
  • Near-flat recline: the backrest can be lowered to a flatter position in and out of the car for more comfort on longer trips.
  • Extra side protection (L.S.P. Plus): CYBEX says it reduces the impact of a side collision by about 15% compared with the same seat without it in a test to ADAC criteria.
  • Grows with your baby: the headrest and harness height adjust together with one central adjuster, and you only move up to the next seat when your baby's head reaches the top of the shell.
  • With the Base G (sold separately): Isofix installation with a support leg, 180° rotation towards the door and a one-click release. The same base later fits the Sirona G i-Size.
  • Approved for use on certain aircraft according to CYBEX and ADAC (check with your airline when booking), and it clicks onto compatible CYBEX strollers.

Who it suits

  • Newborns from 40 cm up to about 18 to 24 months, 87 cm or 13 kg, whichever comes first.
  • Parents who want an infant seat with high scores in independent crash tests and who move their baby between car and stroller often.

Limitations

  • Expensive, and the Base G is not included, adding a significant cost if you want Isofix installation and rotation.
  • Without the base it installs with a 3-point vehicle belt only; ADAC noted a slightly higher risk of incorrect use, slightly fiddlier buckling and a cover that is hard to remove.
  • On the front passenger seat the front airbag must be deactivated (per ADAC).
  • Limited view out for the baby because of the deep shell (per ADAC).
  • Few ratings for this colour on Amazon.sa so far (26 at the time of review).
  • The manufacturer says the seat should not be used for more than 8 years (per ADAC).

Care

The fabric covers are machine washable at 30°C according to CYBEX. Follow the manual to remove and refit them correctly.

Why this rating?

Our assessment is based on published test results and shopper ratings; we did not test the seat ourselves. In ADAC's 2024 test it scored 1.5 for safety and 2.0 overall without a base, and 1.8 with the Base G, and it holds 4.7/5 on Amazon.sa, though from few ratings. The score is held back by the premium price with a separately sold base and a limited usage span up to about 87 cm.

A good fit if

  • If your car has Isofix, the Base G makes installation easier per ADAC, so budget for it
  • Make sure the seat position has a 3-point belt, and deactivate the front airbag if you install it on the front passenger seat

Product strengths

  • Very good crash results in ADAC 2024 (safety 1.5 without base)
  • Near-flat recline for longer trips
  • 180° rotation and one-click release with Base G
  • Headrest and harness adjust together with one control
  • Approved for certain aircraft and fits CYBEX strollers

Before you buy

  • Premium price, and the Base G costs extra
  • Without the base, ADAC noted slightly higher misuse risk and fiddlier buckling
  • Fabric cover is hard to remove (ADAC)
  • Few Amazon.sa ratings for this colour so far
