An i-Size high-back booster seat that enhances safety through comfort

Superior safety and protection

Combining safety and comfort, Thule Palm ensures your child stays securely positioned throughout the journey, even on longer rides. The design, including the optional Thule Palm footrest (sold separately), prevents pain and numbness by supporting blood circulation and posture, keeping your child comfortable and safe. This way, the advanced Thule Side Impact Protection and large protective headrest can provide maximum safety, giving you peace of mind on every trip.

Easy installation

Thule Palm is designed for easy installation with an intuitive belt guide system that helps ensure a secure fit every time. While the integrated ISOFIX hooks are specifically for fixing the seat in place, they contribute to overall stability. This setup gives parents peace of mind while encouraging kids to learn how to buckle up (with a final check from the caretaker, of course). The belt routing and guide system minimizes the risk of incorrect installation, ensuring safety and comfort. Additionally, the reclining backrest adjusts for added comfort, providing a better fit in any vehicle seat.

Premium comfort and sleek design

Longer journeys have never been as comfortable as with Thule Palm, addressing the true pain points of an uncomfortable seat. This booster seat features a unique comfort foam cushion, a large comfortable headrest, seat recline, and the option to attach the Thule Palm footrest accessory (sold separately) for added leg support. The seat has a premium finish and detailing with a sleek design that appeals to both parents and children, making every trip stylish and enjoyable.

All our car seats/bases are compatible with i-Size car seat requirements. However, not every car seat may fit comfortably in vehicles designed for i-Size car seats.

Our fit assistant will guide you in determining if the car seat can be comfortably installed in your vehicle and assist in finding the optimal placement for the car seat.

What is i-Size

i-Size is a European standard for car seats that prioritizes safety and compatibility, focusing on a child's height instead of weight. It guarantees a near-universal fit across car models with secure and easy ISOFIX point installations.

Check your car's manual or look for the i-Size icon to confirm compatibility.

What is ISOFIX

ISOFIX provides a standardized, belt-free method for car seat installation, directly connecting to the vehicle’s chassis for enhanced stability and security. Verify your car's compatibility with ISOFIX anchor points before choosing a car seat.
