The Kinderkraft Safety FIX 3 PRO sits at number 9 in this guide. It is listed at £68.23, with a 4.5 rating from 254 Amazon ratings, and it covers 76-150 cm — the booster stage, which the listing ties to 15 months to 12 years and calls Group 1-2-3. The bullets promise ISOFIX and Top Tether, with vehicle seat belt fitting as an option, a 5-point harness with soft pads, an Easy Grow system that moves headrest and harness together without rethreading, and H-Guard plus SPS side protection.

The problem is in the spec table, and it is not a small one. Orientation is listed as Rear Facing, and Rear Facing Maximum Weight as 18 kg, on a seat whose own name and bullets describe a 76-150 cm forward-facing booster for a child up to 12. Installation Type is listed as Latch, while the bullets promise ISOFIX and Top Tether. On a seat at this stage, which way it faces is the whole product, not a detail. Everything below comes from the Kinderkraft Safety FIX 3 PRO listing on Amazon, not from testing we carried out ourselves.

## Questions people ask

**Is the Kinderkraft Safety FIX 3 PRO rear facing?**

The spec table says Orientation: Rear Facing, with a rear-facing maximum weight of 18 kg. The product name and bullets describe a 76-150 cm seat used from 15 months to 12 years, which is the forward-facing booster stage. The listing does not explain the two together.

**How does the Kinderkraft Safety FIX 3 PRO install?**

The bullets say ISOFIX and Top Tether, with optional vehicle seat belt installation depending on the child's height. The spec table lists Installation Type as Latch, which is a different fitting system.

**What size of child does the Kinderkraft Safety FIX 3 PRO fit?**

The listing gives 76-150 cm and 15 months to 12 years, described as Group 1-2-3, with a minimum weight recommendation of 9 kg and a maximum of 36 kg.

**Does the Kinderkraft Safety FIX 3 PRO have a harness?**

Yes. The bullets describe a 5-point harness with soft pads, and the spec table lists Harness Type as 5-Point. The Easy Grow system adjusts the headrest and harness in one movement without rethreading.

**What is the rating breakdown?**

The listing shows 4.5 out of 5 from 254 ratings. The breakdown it prints adds up to 100, not 254 — 78 five-star, 9 four-star, 7 three-star, 1 two-star and 5 one-star — so those figures read as percentages rather than counts.

**How heavy is the Kinderkraft Safety FIX 3 PRO?**

The listing gives an item weight of 7.31 kg and dimensions of 38 x 45 x 57 cm (depth x width x height), in black.
