From 5-Point Harness to Belt-Positioning Booster
The Nuna LUMN is an investment designed to last. It seamlessly transitions with your child's growth, providing a decade of use from one smart purchase.
Harness Mode: Secure for Your Little Kid (30-65 lbs.)
For children between 30-65 pounds and 34-49 inches, the 5-point no-rethread harness provides the highest level of safety. The harness is easy to adjust as your child grows and features padded covers for comfort. When it's time to transition, the harness system stows away neatly within the seat, which is really convenient.
Booster Mode: Independence for Your Bigger Kid (40-110 lbs.)
Once your child reaches at least 40 pounds and is between 43-57 inches, the LUMN transforms into a high-back belt-positioning booster. The open belt path and clear color-coded guides empower your child to learn how to buckle themselves in safely, using the vehicle's own seat belt.
One-Hand, 10-Position Headrest for the Perfect Fit
A proper fit is essential for both safety and comfort. The headrest adjusts with just one hand through 10 different height positions, ensuring the shoulder belt is always positioned correctly across your child's collarbone as they grow.

Why the Nuna LUMN is a Great Purchase
Investing in a premium car seat is a decision first about safety, but then value and daily convenience are also very important. The Nuna LUMN excels in all three areas, making it a purchase you can feel good about for years to come.
- Long-Term Value: With a 10-year lifespan, the LUMN is built to be the final car seat your child will ever need. It covers the entire period from when they outgrow their convertible seat until they can safely use the vehicle's seat belt alone, offering incredible value over its lifetime.
- Premium Materials and Effortless Cleanup: Life with kids is messy. The LUMN is designed for it. The high-quality micro-knit fabric and leatherette accents are durable and easy to wipe clean. For bigger messes, the seat pad is fully machine-washable.
- Features That Truly Matter: From the True Tension™ door that simplifies installation to the adjustable leg rest that enhances comfort, every feature on the LUMN is designed with a purpose. There are no gimmicks.
Frequently Asked Questions about the Nuna LUMN
Q. Is the Nuna LUMN worth the extra cost compared to the Nuna AACE?
A: The LUMN is worth it for parents prioritizing an all-steel frame for maximum structural integrity and the True Tension™ door for a foolproof (harness) installation. The AACE is an excellent booster, but the LUMN provides a more robust harness-mode experience with more premium features like the leg rest.
Q: How hard is it to install the Nuna LUMN?
A: The LUMN is designed for an easy and secure installation. In harness mode, the True Tension™ door simplifies the process of using a vehicle seat belt. In booster mode, the push-on LATCH connectors keep the seat stable for your child to climb in and out.
Q: Will the Nuna LUMN fit in my car with two other car seats?
A: With a width of only 18.25 inches, the LUMN is one of the slimmest combination seats available. It is designed to fit 3-across in most mid-sized vehicles. We always recommend measuring your back seat to confirm.
Q: What is the main benefit of the adjustable leg rest?
A: The leg rest provides ergonomic support for a child's legs, preventing them from dangling uncomfortably on long rides. This improves circulation and overall comfort, reducing restlessness and complaints.
Q: How do you clean the Nuna LUMN?
A: The fabrics and inserts are machine washable on a delicate cycle (cold water, mild detergent, lay flat to dry). The plastic and leatherette components can be wiped clean with a damp cloth.
Q: Can I use the Nuna LUMN on an airplane?
A: Yes, the Nuna LUMN is FAA certified for use on aircraft when in harness mode. It is not certified for use in booster mode, as booster seats require a lap-and-shoulder belt.
