Latest Review
Rated 5.0 out of 5
This Miniuno InfinityFix car seat has made our daily London commute easier, it's all the small things that count! As a mum of two living in Greenwich, the true 360° rotation makes school drop-offs so much easier, especially in tight parking spots. The ventilation system is brilliant during busy tube-side parking in summer, keeping my little one cool and comfortable. Installation was effortless with our BMW's ISOFIX points, and the support leg gives extra stability. After six months of use, I'm impressed by the fabric quality and how easily it cleans after inevitable snack spills.

Miniuno InfinityFix R129 360° Swivel Car Seat FAQs

The InfinityFix features a unique rotation system that turns completely smoothly in both directions, making it easier to get your child in and out from either side of the car. Unlike standard swivel seats, our true 360° mechanism allows rotation while the support leg is installed, providing continuous stability. This means you can switch between rear and forward-facing positions effortlessly without compromising safety.

The InfinityFix's built-in airflow system is integrated directly into the seat's shell, creating constant air circulation around your child. This innovative cooling system includes strategically placed ventilation channels that help regulate temperature in both hot and cold weather. It's particularly helpful during summer months or for children who tend to get warm in car seats.

Yes, the InfinityFix is designed for use from birth (40cm) up to approximately 12 years (150cm). It includes a specially designed newborn insert for optimal support and positioning of small babies. You can use it rear-facing from birth to 105cm (around 4 years), and then forward-facing from 76cm to 150cm. The 5-point safety harness can be used until your child reaches 105cm.

The seat covers are fully removable and machine washable at 30°C. The premium fabrics are designed to be stain-resistant and easy to wipe clean for quick spills. You can remove the covers without uninstalling the seat base, and all padding pieces are clearly labeled for easy reassembly. The ventilation system helps reduce sweating, which means less frequent cleaning is needed.

Not at all - the InfinityFix features a straightforward ISOFIX installation system with clear visual indicators showing when it's correctly fitted. Simply click the ISOFIX connectors into your car's ISOFIX points until you see the green indicators, then adjust the support leg until it's firmly on the floor. The seat includes easy-to-follow installation guides, and the support leg has height markers to ensure proper positioning.
