Nuna Relx Wind Car Seat

Nuna RELX wind Rotating Car Seat with Built-In Ventilation

Keeping little ones settled on the move just got easier with the Nuna RELX wind, a rotating car seat built for extended rear-facing use from birth right through toddlerhood.

Extended Rear-Facing Protection, Built to Grow

Rear-facing use runs from 40 cm up to 105 cm and under 18 kg, supported by a no-rethread 5-point harness that adjusts as your child grows, and a 6-position height-adjustable headrest for a proper fit at every stage. A smart-swivel lock keeps the seat safely rear-facing until your child is at least 15 months old and 76 cm tall — a good match if you're looking to extend rear-facing travel as long as possible, which is exactly what our extended rear-facing car seat range is built around.

Built-In Ventilation System

The built-in ventilation system keeps children cool and comfortable, with 3 speed levels controlled from an easy-to-use remote alongside the seat's recline positions. An auto memory function means the seat simply returns to the last-used recline and fan setting, and the control panel locks itself after 30 seconds of inactivity to prevent accidental changes mid-journey.

360° Rotation for Easier Loading

A smooth 360° spin takes the strain out of loading and unloading, so there's no awkward reaching or twisting required to get your little one settled. If rotation is top of your list, it's worth browsing our full rotation car seat range to compare options.

Safety and ISOFIX Installation

Safety runs right through the build. Harness pads and a detachable Side Impact Protection pod (usable on either side of the seat) are made with EPP energy-absorbing foam, backed by Nuna's patented Tailor tech memory foam for extra cushioning on impact. An integrated rebound bar helps limit rotation in a collision, and installation uses True lock base technology with ISOFIX anchor points, 10-position adjustment against the vehicle's seat backrest, and clear colour-coded indicators to confirm a secure fit — including a stability leg that shows green when properly grounded. The RELX wind meets the European i-Size standard (ECE R129/04).

Comfort and Premium Details

For sunnier days, a retractable sun canopy adjusts with the headrest and offers UPF 50+ protection, while airy mesh fabric is designed to help minimise overheating. Removable infant head and body inserts give smaller babies a snugger, more supportive fit, and magnetic buckle holders keep the harness tidy and out of the way while you're getting your little one settled. Power comes via USB-C from the car, with 3 AA batteries included as backup and a low-power warning to remind you when it's time to recharge — and as they grow out of the infant stage, it holds up well as one of our toddler car seats too.
