The Mazda 3 has limited space in the backseat for a car seat installation. Whether using ISOFIX anchors or the vehicle’s seatbelt, it can accommodate up to 2 child car seats. Most Mazda models, come equipped with ISOFIX anchors, but always double check your vehicle if you are unsure. In this article, we’ll show you how to install PERO booster seats in a Mazda 3, with step-by-step guidance and important tips to help ensure a safe and proper setup.
Mazda 3 Child Car Seat Installation Guide
The Mazda 3’s rear seats are equipped with a Seat Gap-Style, the anchor points are located between the seat base and backrest. If you’re unsure where the U-shaped anchors are, simply reach into the seat gap to locate them by hand. Most Mazda models—even older ones—come equipped with ISOFIX lower anchors, so we recommend checking the seatback for ISOFIX tags or labels as a quick way to confirm.

Mazda 3 with PERO Installation Example
如果Mazda 3想安裝兩台以上的PERO安全座椅或增高墊,建議可以考慮WIDFIX ISOFIX延伸器。不過須特別注意的點是,Mazda 3的ISOFIX裝置藏在椅縫中不好對準,且坐墊的中間處較左右低,使用WIDFIX ISOFIX延伸器,安全座椅可能會傾斜,建議使用WIDFIX高低墊對折後維持水平。If you’re looking to install more than two PERO car seats or booster seats in a Mazda 3, the WIDFIX ISOFIX extender is a helpful solution to create additional space. However, there are a few key points to keep in mind: the ISOFIX anchors in the Mazda 3 are hidden deep within the seat gap, making alignment a bit tricky. Also, the center portion of the rear seat is slightly lower than the sides, which may cause the car seat to tilt when using the WIDFIX extender. To keep the seat properly level, we recommend folding the WIDFIX leveling pad in half for added stability.
