Safety beyond the test lab

TinySeats is developed around proven child-safety principles, rigorous testing, and engineering focused on real-world use.

We reduce injury risk not only in crash situations, but also in everyday use — where correct installation, durability, and long-term fit play a crucial role in keeping children safe every day.

Certified to UN R129 (i-Size)

TinySeats is certified according to UN R129 (i-Size), the latest European safety regulation for child car seats.

This standard requires testing in both frontal and side-impact collisions, as well as improved compatibility with modern vehicles.

R129 certification means the seat meets internationally recognised safety requirements — for trusted peace of mind.

The Swedish Plus-test

The Swedish Plus Test is a voluntary certification that manufacturers can pursue in addition to R129 approval. It is known for its strict focus on measuring forces on the child’s neck in a frontal collision and to be of the most demanding safety tests in the world.

Because the Plus Test is only applicable to rear-facing car seats, only seats designed exclusively for rear-facing use can be certified.

A dedicated rear-facing version of TinySeats Two is currently in development, built on the same safety structure, with the aim of enabling Plus Test certification. Planned for 2026.
