It creates a perfectly level platform, making it more stable and secure than traditional fiber-bottom extenders for long-distance travel.

The anti-slip devices and secure zippers minimize wobbling even during sharp turns, ensuring maximum safety for active pets.
【Visible Mesh Window for Anxiety Relief】The front panel is equipped with a reinforced mesh window that provides 360° ventilation. This allows constant airflow and keeps your pet visible, significantly reducing travel anxiety while enabling the owner to monitor pet status at any time during the drive.
