Multi-height child restraint systems (CRS) are seats that can switch from rear-facing to forward-facing to accommodate different child height groups in a single seat. These seats require different safety features as a child grows. Many products on the market attempt to combine users of multiple age groups into a single product, but most do so at the expense of the product’s effectiveness. Q88 i-Size Child Safety Car Seat is designed for children ranging in height from 40 to 125 centimetres and consists of several design features that improve usability and discourage product misuse. This increases the child’s safety in a vehicle.
