The Integrated Child Seat meets all FMVSS and CMVSS requirements and can be easily converted into one of SynTec’s other school bus seating solutions, such as the Lap/Shoulder Seat or the Lap Belt Ready Seat.  With no loss for capacity, the S3C Integrated Child Seat’s unique design allows the seat to be converted to and from any configuration in less than 2 minutes without removing the seat.  Time saving for employees and cost-effective for school districts.  Another great feature of this Integrated Child Seat, and SynTec’s other school bus seating products, is the ability to retrofit any SynTec seat to fit all Thomas buses.
