⭐ Why Parents Choose the MaxSpace Smart

The MaxSpace Smart is designed to maintain natural spinal alignment throughout growth. Features include:

• Contoured lumbar support to maintain a natural curve

• Deep seat base for proper pelvis positioning

• Coccyx pressure relief zone to reduce discomfort on long trips

Very few child seats meet AGR's strict ergonomic standards—MaxSpace does.
