This cheerful whale-shaped Moby tub-in a fresh color we like to call baby Beluga-grows with baby through three stages and offers Smart Sling support. The sling locks into two ergonomic positions- higher for full-body support and lower for seated support. Quick-drying mesh and comfort-edge construction securely cradles baby from head-to-toe. The slings adjusts to a cushioned seat that comfortably supports babies learning to sit. Remove the sling when baby has mastered sitting and easily bathe baby in the spacious tub-no uncomfortable plastic bumps.
