Britax KidFix Pro Highback Booster Car Seat

Picture a safe space for your child — a cozy, secure haven where they can calm down and feel at home. The KIDFIX PRO, from Britax Römer's test-winning KIDFIX line, is designed to be exactly that. Made in Germany, this highback booster impresses with a one-of-a-kind safety combination — SICT, the energy-absorbing XP-Pad and the SecureGuard* belt guide. Its slim design fits seamlessly into every car while offering plenty of room for your child to grow, from 100–150 cm (15–36 kg, approx. 3.5 to 12 years). *SICT and the XP-Pad feature on every KIDFIX PRO; the SecureGuard is added on the STYLE & LUX collections.

Safety beyond standards

Nothing is more important than your child's safety, so the i-Size (R129) approved KIDFIX PRO is engineered to protect from every angle. SICT (Side Impact Cushion Technology) and the energy-absorbing XP-Pad help shield your child in both side and frontal impacts on every KIDFIX PRO, while the SecureGuard* adds a fifth belt-guide point for correct lap-belt routing on the STYLE and LUX collections. Every detail is developed in Germany, so you can feel confident every time you buckle up. *SecureGuard: STYLE & LUX only.

Comfort as they grow

From around 3.5 to 12 years, the KIDFIX PRO delivers ultimate ergonomics. Soft padding and a slim yet spacious design keep your little one comfortable on every journey, and the easy-adjust, V-shaped headrest grows alongside your child for the perfect fit. Carefully placed air-ventilation holes add a touch of coolness on warmer days — and the STYLE collection adds breathable mesh fabrics for superior air circulation.

Easy handling, maximum flexibility

Weighing just 6.7 kg, the KIDFIX PRO is a featherweight in the world of car seats — effortless to move between cars without the usual hassle. Its slim shell helps you fit three seats across the back row, and installation is as simple as it is secure thanks to the integrated ISOFIX connectors: a quick, reassuring click and you're ready for the road.

Choose your collection

The KIDFIX PRO comes in three fabric collections. CLASSIC — lasting comfort in a soft, high-quality fabric. STYLE — fine mesh fabrics for superior air circulation. LUX — luxurious, sustainable fabrics with leatherette details. SICT and the XP-Pad feature across every collection; the SecureGuard belt guide is added on STYLE and LUX. We stock the STYLE (Teak) and LUX (Soft Taupe & Linen Grey) collections — so all three colours we carry include the full SICT, XP-Pad and SecureGuard safety combination.
