As your child grows, the MPS can grow with them. By adding the optional Extended Seat Cushion, the life of your MPS will extend. The ideal time to purchase the Extended Seat Cushion is when your child's thigh depth and hip width have outgrown the standard seat cushion. You can extend the life of your MPS by 7 years with the addition of the Extended Seat Cushion.
Seat Width = 10"
