This Ergobaby Alta Hip Carrier is a 2-in-1 ergonomic baby carrier and hip seat that grows with children from 4 months to 4 years (5.5–22 kg). This convertible carrier switches easily between four carrying positions—inward-facing, outward-facing, hip and back—and the removable upper panel transforms it into a stable hip seat for quick lifts and short adventures. This design prioritizes comfort with a wide padded waistband for back support, a structured hip seat that promotes a hip-healthy "M" position, and a ventilated mesh panel to keep both wearer and child cool. Made from durable 100% polyester with adjustable straps and supportive padding, this infant and toddler carrier is ideal for everyday outings. Includes the ErgoPromise lifetime warranty from Ergobaby for lasting reliability and peace of mind.
