The Polisport Koolah CFS Rear Child Bicycle Seat is one of Polisport’s most popular models, offering excellent safety and comfort at an affordable price. Designed for children aged 9 months to 5 years (up to 22 kg), the Koolah CFS mounts directly to the bicycle’s luggage carrier using the CFS system—no tools required.

The seat includes a 3-point adjustable harness, childproof buckle, extra security frame belt, and large foot protection to prevent contact with the wheel. Increased lateral protection and ergonomic armrests ensure a safe and comfortable ride.

To grow with your child, the Koolah features 4-position adjustable footrests, 2 height options for the harness, and the ability to move the seat backward or forward depending on the bicycle and child size. The waterproof cushion is removable for easy cleaning, and the helmet-friendly design ensures proper head positioning.
