Image: Stable Pyramid Frame. The wide stance design of the high chair's base significantly reduces the risk of tipping, even if a child leans forward or reaches to the side. This design has passed lateral stability and forward tipping tests under simulated toddler movement.

Image: Padded Safety Harness. The 5-point harness system includes padding to prevent chafing and ensure comfort for active toddlers, keeping straps from digging into shoulders or waist.
