Growing with style

It seems as if the little ones never stop growing! No problem for the Nuna AACE LX child seat. Thanks to the 3D Growth System™ and sleek, timeless design, it adapts perfectly to every child - from pre-schoolers to almost-teens. The seat of the stylish car seat can be adjusted in three stages. In addition, the shoulder width adjusts automatically as soon as the headrest is set to one of 17 positions. With the practical cup holder, drinking bottles and cups are always within easy reach and securely fastened. The open design of the AACE LX makes it easier for your child to get in and buckle up independently. Your little one is secured with the vehicle seat belt during the journey.

The Nuna collection

Nuna inspires with its unique style, inspired by the clean lines and sophistication of Dutch design. The result is baby equipment that is simple, safe and flexible, just as young parents need it.

Growing comfort combined with maximum safety

The child seat allows absolutely no compromises - neither in terms of safety, comfort or style! The side impact protection with energy-absorbing EPP foam protects your baby's head and neck area in particular. The attachable side impact protection element offers a further safety aspect to protect your child. The integrated energy-absorbing foam significantly reduces the impact forces.

Thanks to the 3D Groth™ system, the seat can be adjusted in height, width and depth to the size of your child. When you adjust the headrest, the shoulder width also expands automatically. You can adjust the height in 17 positions with one hand. The seat can be adjusted in 3 positions to suit the length of your child's legs. The tilt-adjustable backrest adapts perfectly to the vehicle seat.

In the car, the Acce LX child seat is secured using the Isofx connectors or the vehicle seat belt. A colored belt guide ensures optimum positioning of the vehicle belt and therefore intuitive and secure fastening.

The soft and cuddly seat cover made of natural materials ensures that your child feels comfortable on every journey.

If the cover of the Nuna Acce LX i-Size child seat gets stained, you can simply remove it and wash it in the washing machine.

However, the proper use of this child booster seat reduces the risk of serious or fatal injuries to your child.
Always ensure that the installation instructions are followed correctly. This ensures that the booster seat provides optimal safety.

To use this child booster seat in accordance with UN Regulation R129, your child must meet the following requirements.
Child’s height 100 to 150 cm (corresponding to an age of 3.5 to 12 years). Forward facing only (in the direction of travel of the vehicle).

Never leave the child UNATTENDED in the booster seat or in the vehicle, even for a few minutes.
Luggage and other items that could cause injury in an accident should be properly secured.
The child booster seat should not be used without the textile parts.
