Liberty Onyx Booster Seat 

The Liberty Onyx is a convertible Booster Seat suitable for children aged approximately 6 months to 8 years.

It is first used as a harnessed car seat with the in-built six point harness and then converts into a Booster Seat used with the vehicle lap sash seat-belt once the child's shoulder meets the middle shoulder height marker. In Booster Seat mode, it is one of the tallest Booster seat on the New Zealand market, meaning children will get more use out of Liberty than any other booster seat. The Liberty is unique in it being the only convertible booster seat in New Zealand that is foldable, making storage and transport quick & easy. 

Active Fabric™

Liberty features our new easy-care Active Fabric Onyx covers which are hard wearing, cool & breathable. The machine- washable press stud covers can easily be removed for cleaning, as can the shoulder pads. Onyx covers are as beautiful as they are practical. 


Secur- air works hand in hand with Air Cocoon Technology (A.C.T) to dramatically reduce crash energy to the child's head. Liberty comes with A.C.T as a standard feature, which alone reduces crash energy to the child more than five times lower than the level required by the 2013 Australian Standard. With the addition of Secur-air, your seat gains a third layer of protection for your child's head area, making it one of the safest seats to date we have ever produced. 

Air Cocoon Technology™ (A.C.T)

Air Cocoon Technology (A.C.T) enhances protection by dramatically reducing the impact force during a crash A.C.T utilises a layer of air held within the entirety of the restraint shell, offering an increased level of protection across the entire surface area of the restraint. Your child is quite literally cradled in a cocoon of air, offering a true 180 degrees of protection to your child's vital organs.
