Not Recommended After many years the rally has not be updated and is still a very wide seat and the additional slots above the booster marker tend to allow parents to mis-use the seat. Despite the many advantages it originally came with the rall can no longer be recommended..
Infa Secure Rally Review
Recommended. This car seat is for everyone who wants a top rated forward facing restraint which features, and introduces new innovations in safety, comfort and ergonomics. The Infa Secure Rally has Air Cocoon Technology, to keep your child safer. Unlike other manufacturers this technology is only available in their premium seats
Anti Submarining by Design
The Rally child restraint includes a larger seat-belt path, and a unique anti-submarining technology, resulting in a very safe, and comfortable convertible booster seat.
INFA have incorporated a ‘pommel’ design into the seat base, and the air-bag-like blow molded construction acts in a similar way to air bags.
The sloped surface results in a larger downward force, rather than lateral, decelerating the child and reducing forward motion and submarining.
The Rally features a high, blow molded backrest with large side wings for enhanced side impact protection. The recline position for your child’s comfort.
The Rally is a forward facing child restraint, and can be used with the in-built harness from approximately 6 months through to 4 years old. Once your child reaches the middle shoulder height marker, you can convert the Rally into a booster seat.
Rally Car seat in Booster Mode

In booster seat mode, the anti-submarine designed arm rests work in tandem with the new base; keeping the lap belt down across your child’s lap. The included Safe-Grip Belt Clamp ensures the lap belt does not ride up into your child’s abdominal area.
Summary Infa Secure Rally Car seat Review
Not Recommended : When first released the Rally from Infa Secure, was a great seat incorporating features such as A.c.t. side and head protection at a budget price. However 10 years later it is an old design, with very wide wings making it difficult to install more that two seats in the second row of most cars.
