Description

The Nuna ARRA Flex Infant Car Seat, Caviar is crafted for modern families who need a travel solution that is both safe and exceptionally convenient.

Key Features: 
  • Three recline positions including a 157° near-flat recline usable in the car, on a pushchair, or during air travel.
  • Ergonomic lie-flat design supports ideal head, spine, and hip alignment and removes the usual two-hour usage limitation.
  • i-Size (R129) certified for advanced safety standards, including side-impact protection testing.
  • EPP energy-absorbing foam enhances side-impact security and reduces crash forces.
  • Patented Tailor tech™ memory foam headrest for a custom, secure fit that grows with the child.
  • Compatible with BASE next and BASE curv, offering 360° rotation and simple click-on installation.
  • Vehicle belt installation option for flexibility when travelling without a base.
  • TÜV-certified for air travel, allowing safe in-flight installation using a lap belt.
  • Lightweight construction, weighing just 3.8 kg (excluding insert and canopy) for easier carrying.
  • Premium newborn insert made from Merino wool and TENCEL™ lyocell blend for natural temperature regulation.

Designed to support busy days, long journeys, and everything in between, the ARRA Flex provides an impressively smooth transition from home to car to pushchair. Its standout feature is its ability to recline into a near-flat position—an ergonomic 157° angle—giving newborns a comfortable, developmentally supportive posture whether in the vehicle, on an aircraft, or when used as part of a travel system.

Weighing just 3.8 kg (excluding insert and canopy), the ARRA Flex combines lightweight handling with uncompromised strength. It meets the highest i-Size (R129) safety standards and incorporates advanced side-impact protection through EPP energy-absorbing foam. Nuna’s patented Tailor tech memory foam in the headrest further enhances security by contouring to the baby’s shape for a precise, comfortable fit.

Versatility is at the heart of the ARRA Flex. It can be installed on the BASE next or BASE curv for fast, click-and-go 360° rotation, or used safely with a vehicle seat belt when required. It is also TÜV-certified for air travel, allowing families to maintain the same ergonomic recline and support during flights. The no-rethread harness, one-handed headrest adjustment with ten positions, and removable newborn insert help the seat adapt effortlessly as the baby grows.

Thoughtfully chosen materials elevate the experience further. The Merino wool and TENCEL blend newborn insert offers natural softness and temperature regulation, while the UPF 50+ canopy with eyeshade and mesh panel ensures comfort in warm weather. Luxe touches such as the leatherette carry handle and refined design details complement the seat’s premium engineering.

With multiple prestigious awards—including European Product Design, Red Dot, and iF Design—the Nuna ARRA Flex Infant Car Seat stands as a refined safety solution that brings together ergonomic innovation, usability, and elegant craftsmanship.
