All children should continue to use a child restraint with a five-point harness for as long as possible.  Like all boosters, children should start using hifold when they have outgrown their car seat with a 5-point harness and when they can sit in the booster seat properly for the entire duration of each. 

Sitting properly means that the child must remain seated without slouching under the lap belt, moving shoulder belt under arm or behind back, or leaning forward or sideways moving out of position so the vehicle belt remains properly positioned.

hifold has one of the broadest height and weight ranges for a highback booster. hifold can be used by children aged 4 and up, weighing 40 pounds to 100 pounds) and 40” to 59” tall.

hifold has a patented design which optimizes the seat belt fit of the lap belt and chest belt in order to fit the child. hifold is a booster seat that is regulated for global use and meets or exceeds all the relevant car seat safety standards including NHTSA FMVSS 213 for the US, UN ECE R44/04 for most countries, the RSSR regulations in Canada, CCC for China and various local versions for other markets.  This means that, wherever you buy your hifold seat, it can be used in every country on earth.*

 * Except Australia where regulation is pending.

The forward movement of the hifold seat back has been specifically designed to improve safety and comfort This forward movement actually keeps the seatbelt shoulder belt optimally positioned on the child’s clavicle bone (between the neck and the shoulder). Traditional highback boosters are rigid structures. As a child leans forward, so that the seat belt is pulled through the shoulder belt guide, the greater the risk that the seat belt will slip off the child’s shoulder. With hifold, the shoulder belt guide moves with the child, maintaining the optimal seat belt shoulder belt position.

Currently in the USA, there are no side impact testing protocols defined in the regulations for highback boosters. The National Highway Traffic Safety Administration (NHTSA) is the agency within the U.S. Department of Transportation that defines testing protocols for child restraint systems such as hifold. Specifically, we follow and comply with the Federal Motor Vehicle Safety Standard FMVSS 213. Within this standard, NHTSA has not yet defined any side impact testing protocols for highback boosters. Therefore, we cannot make any statements about side impact testing or about the performance of our child restraint systems in side impact collisions.

The hifold fit-and-fold booster seat is not available for sale or use in Australia. The Australian car seat standards are completely different from those in the rest of the world.  The Australian regulations require a top tether on highback boosters above a specific seat weight. This is not required anywhere else in the world and currently, we do not manufacture a version of hifold with a top tether
