Our cheerful whale-shaped Moby tub 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. Dual layered 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.
