Adult waist size

Fits most adults with a waist size of 27–45 inches (70–115 cm). The belt should sit snugly above your hips for proper support.

How the fit should look

Your baby’s legs should naturally form an M‑shape Your baby’s bottom should sit fully on the seat Your baby’s spine should be supported without slumping Your waist belt should feel secure without digging in
