Review: Sturdy, safe and easy to use - We bought the Maxi-Cosi Tanza i-Size for our child after moving on from the infant carrier, and it’s been a great choice. The seat feels really solid and well-built, which gives us peace of mind. Installation with the ISOFIX connectors was straightforward and the seat sits very securely once clicked in. Our little one seems comfortable on both short trips and longer drives—the padding is supportive without being bulky, and the seat has a good ergonomic shape. Adjusting the headrest is simple and quick, so it will be easy to adapt as our child grows. Another plus is that it doesn’t take up too much space in the back seat compared to some bulkier models. The cover feels durable and is also removable for washing, which is a lifesaver. Overall, the Tanza i-Size is exactly what we were looking for: a safe, well-made seat at a fair price, with the reassurance of Maxi-Cosi’s reputation. Would definitely recommend.
Review: Great seat and very portable - I recently purchased the Maxi-Cosi Tanza and had the opportunity to truly put it to the test during a trip to France. I must say, this car seat exceeded all my expectations, particularly in terms of travel. One of the standout features of the Maxi-Cosi Tanza is its lightweight design. Traveling through airports, navigating rental cars, and transferring between vehicles was a breeze. The car seat's compact size made it easy to carry and fit into smaller European cars, which was a big plus on our trip. Despite its lightweight construction, it feels sturdy and reliable, providing peace of mind that my child was safe and secure. Throughout our travels in France, we used the Maxi-Cosi Tanza in several different vehicles, ranging from small city cars to larger SUVs. I was impressed by how well the car seat fit in each one. The adjustable headrest and easy-to-use installation system meant that switching between cars was quick and hassle-free. It sits securely and comfortably, regardless of the vehicle's size or shape. Even on longer drives, my child remained comfortable in the Maxi-Cosi Tanza. The seat's padding is plush without being overly bulky, and the adjustable headrest allows for a perfect fit as your child grows. Safety is always my top priority, and I felt confident knowing that this seat meets all safety standards while providing a comfortable ride for my little one. The Maxi-Cosi Tanza has proven to be an excellent investment, especially for families who travel frequently. Its lightweight and compact design made our trip to France much easier, and its versatility means I can use it confidently in any car. I highly recommend the Maxi-Cosi Tanza to any parent looking for a reliable, travel-friendly car seat that doesn't compromise on comfort or safety.
