From the official announcement: Utter simplicity. An all-beige carrying sling. This product is an onbuhimo (a type of baby carrier) for children with disabilities, suitable for carrying pre-schoolers and the elderly. It was created in response to requests. The back panel is long and large to accommodate children with disabilities aged 3 and older. Darts are incorporated in the seat area for a better fit. It can also be used for the care of the elderly (depending on the build of the person being carried). If the caregiver is of a larger build, please consider the "Plus Size for Children with Disabilities" version in denim. ■ Special Size Basic Specifications Target Age: From when the neck is stable Material: Shoulder strap length (from the back panel, each side) 140 cm, shoulder strap width 7.5 cm Waist strap length (D-ring to D-ring) 65 cm Back panel length 39 cm, back panel width (top) 27 cm (bottom) 33 cm Suitable Size: Waist 55 cm and up, up to approximately 85 cm (with a square knot) Weight (average): Approximately 420 grams
