Seamless 360° Rotation with Rebound Bar

The All in All Ultra 360 Rotate features effortless one-handed rotation, enhanced by a built-in rebound bar. This innovative design allows smooth, controlled rotation within your vehicle while adding extra protection in the event of a collision.

Rotate the seat easily toward the car door for stress-free access when lifting your child in or out, then lock securely into rear- or forward-facing positions as required. No awkward stretching. No heavy lifting. Just smooth, intuitive movement every day.


Spin for Longer – All the Way to 12 Years

Unlike many rotating car seats, the All in All Ultra 360 Rotate is designed to spin for longer, maintaining its rotating functionality all the way up to 150cm (approx. 12 years). This extended rotation makes everyday use easier as your child grows—whether you’re buckling in a toddler or helping an older child in and out independently.


Premium i-Size Safety, Tested Beyond the Standard

Safety is uncompromising. The All in All Ultra 360 Rotate meets and exceeds the latest R129/i-Size safety standard, which includes mandatory side-impact and rollover testing using advanced crash-test dummies.

  • Tested beyond standard R129 speed requirements

  • Aligned with ADAC levels of testing for enhanced reassurance

  • Pop-out Side Impact Protection System (SIPS) absorbs forces in a side collision

  • Deep side wings and energy-absorbing foam padding for added protection
