Fisher-Price 4-in-1 Sling 'n Seat Tub

The deep molded basin and secure mesh sling hold a newborn steady, and Wirecutter reported it felt safe across 25 hours of hands-on testing with real infants.

Skip Hop Moby Smart Sling 3-Stage Tub

The dual-layer Smart Sling locks in two positions to hold a newborn or a seated infant securely, and its rating stays high across more than 15,000 Amazon reviews.

Fisher-Price 4-in-1 Sling 'n Seat Tub

The soft mesh sling cradles a newborn, and the removable sit-me-up seat gives an older baby a comfortable backrest, making it the roomiest of the tubs tested.

Skip Hop Moby Smart Sling 3-Stage Tub

The contoured whale-shaped basin and adjustable mesh sling keep a baby supported and reclined comfortably as they move through the three stages.

Fisher-Price 4-in-1 Sling 'n Seat Tub

Four stages carry a baby from the newborn sling through the sit-me-up seat to the full basin, which Wirecutter singled out as fitting a growing baby longer than most rivals.

Skip Hop Moby Smart Sling 3-Stage Tub

Three stages take a baby from the newborn sling to a seated infant to a toddler tub up to 25 pounds, nearly matching the Fisher-Price for far less money.

Fisher-Price 4-in-1 Sling 'n Seat Tub

A drain plug, a hang hook, and an included rinse cup make bath and cleanup simple, though the large basin is a chore to store and will not fit in a sink.

Skip Hop Moby Smart Sling 3-Stage Tub

A swivel hook hangs it to dry, the drain empties it fast, and it fits most double sinks, so bathing and storage are both easy.

Fisher-Price 4-in-1 Sling 'n Seat Tub

Fisher-Price is one of the most recognized names in baby gear, and this tub is Wirecutter's tested top pick.

Fisher-Price 4-in-1 Sling 'n Seat Tub

The generous size is the trade-off: it does not fit in a sink and takes real space to store or travel with.

Skip Hop Moby Smart Sling 3-Stage Tub

It fits inside most double sinks and hangs flat to dry, so it stores more easily than the larger Fisher-Price basin.

Strengths & Weaknesses

Fisher-Price 4-in-1 Sling 'n Seat Tub

+ Strengths
  • Wirecutter's top pick after 25 hours of testing with real infants
  • Four stages fit a growing baby from newborn to toddler, longer than most rivals
  • Comes with a drain plug, hang hook, and rinse cup for easy bath and cleanup
− Weaknesses
  • Too large to fit in a sink, unlike an insert or a fold-flat tub
  • Takes up real storage space and does not travel well
  • Costs more than the convertible basins that do nearly the same job
Key flaw: The size that makes it last is also its one drawback.

Skip Hop Moby Smart Sling 3-Stage Tub

+ Strengths
  • Babylist's best basin tub, with a 4.6-star average across more than 15,000 reviews
  • The two-position Smart Sling adjusts as a newborn becomes a seated infant
  • Fits most double sinks and hangs to dry, for about half the price of the top pick
− Weaknesses
  • Three stages instead of the Fisher-Price's four, so a tall toddler outgrows it a little sooner
  • The whale basin is still too big for a single bar sink
  • No temperature-indicating drain plug like the Boon
Key flaw: Three stages instead of four means a tall toddler will outgrow the Moby a little sooner than the Fisher-Price, and the whale basin is still too big to sit in a single bar sink.

The Verdict

Our Bottom Line

The Fisher-Price 4-in-1 Sling 'n Seat Tub is Wirecutter's top pick, chosen after editors spent 25 hours testing ten finalists with their own infants, and it was a tested finalist on The Bump as well. What sets it apart is room and reach: it is the largest, most versatile basin in the group, and it lasts.
