Description
Britax Römer EvolvaFix i-Size Car Seat – Dusty Rose
One car seat from 15 months to 12 years. The Britax Römer EvolvaFix is an i-Size ISOFIX car seat for children from 76 to 150 cm. It starts as a harnessed toddler seat and converts into a highback booster seat as your child grows, so you buy once and use it for years.
5-point harness up to 105 cm
A strong 22 kg 5-point harness with soft neoprene pads keeps your toddler secure and comfortable until they reach 105 cm.
FLIP & GROW: from harness to highback booster in seconds
When your child is ready, stow the harness neatly into the backrest and use the car's 3-point seat belt instead. No extra parts and no second seat needed.
SecureGuard abdominal protection
In booster mode, SecureGuard keeps the lap belt low over the hips, reducing abdominal forces in a frontal collision by up to 35%.
Comfortable at every stage
EasyRecline adjusts the seat into comfortable reclining positions in all stages. The height-adjustable V-shaped headrest grows with your child, and the covers are quick to remove and machine washable.
Secure, simple installation
- 76–105 cm: ISOFIX connectors with Top Tether.
- 100–150 cm: ISOFIX plus the vehicle's 3-point belt, or the 3-point belt only.
It also fits cars without ISOFIX. Clear safety indicators and belt guides confirm the seat is fitted correctly.
Approved to the latest i-Size (R129) standard. Produced and crash-tested by Britax Römer in Germany.
