Thoughtfully designed by certified babywearing educators and experts, the Elevate offers unrivaled comfort and ease-of-use. The adjustable seat provides full support to your infant from newborn to toddler and is certified as hip-healthy by the International Hip Dysplasia Institute (IHDI). This versatile carrier supports six different babywearing positions: fetal position, in-facing (narrow), in-facing (wide), out-facing, back carry, and hip carry. For the fetal position, use the included infant pillow to properly position your newborn in place. Adjusting the carrier seat is simple and intuitive – it takes just a couple seconds! Zip the side panels down and tuck into the waistband pockets to create a narrow seat, perfect for small babies and the outward facing position. When your little one grows, zip up the panels to create a wide seat with extra support for their hips and legs. This carrier also features a snap-into-place three-position headrest, which can be lowered for smaller children, or raised to lengthen the torso of the carrier for older toddlers. The experience of the parent and caregiver is also paramount. Padded, contoured shoulder straps and a structured lumbar support evenly distribute weight providing unmatched comfort for the wearer. The back/chest strap features a one-handed magnetic buckle, making it easy to put on the carrier without a partner present. The carrier is machine washable, lined with 100percent hypo-allergenic cotton lining and featuring a linen exterior with vegan leather detailing. Includes a removable linen sun hood. Supports weight range of 7-45 lbs [3.2-20.4 kg]. One size fits most parents and caretakers.
