Swell 4-in-1 Convertible Crib

The Swell 4-in-1 Convertible Crib by Babyletto is a joyful piece of furniture (we can’t help but smile!). The wavy top and bottom railings — inspired by Babyletto's California roots and the gentle undulations of ocean waves — give it a playful personality that no other crib we carry has. Rounded posts, pop color options, a low-profile silhouette: this is a crib designed to make the nursery feel genuinely happy. Short-parent approved, at just 44.6 lbs one of the lightest full-size cribs in its category.

It is also a serious investment piece. The 4-in-1 convertibility covers crib to toddler bed to daybed with the toddler conversion kit included in the box — and adds a full-size bed conversion (sold separately, #M5789) for the years ahead. Four adjustable mattress height positions. Rounded posts specifically designed so toddlers learning to stand can grip them safely. Hidden hardware throughout.

Built from 100% solid New Zealand pine wood, FSC® certified, GREENGUARD Gold certified, lead and phthalate safe. Every stained-finish Swell is one-of-a-kind due to natural wood grain variation. The Swell collection includes a coordinating changing table for a fully styled nursery.

Specifications

Best For / Not Ideal For

Best For

•       Parents who want the nursery to feel joyful and playful — the wave detailing and pop color options give the Swell a personality no other crib in our lineup has, and no other crib in this category matches

•       Shorter parents: the low-profile design is explicitly short-parent approved, with a front rail to floor height of 31" — meaningfully easier to reach over for newborn placement

•       Families who want the longest possible convertibility path: crib to toddler bed to daybed to full-size bed, with the toddler conversion included and the full-size kit available — this frame can go from newborn through the teen years

•       NYC walkup apartments where crib weight matters: at 44.6 lbs, the Swell is one of the lightest full-size cribs available, making delivery, setup, and any future rearranging significantly more manageable

•       Parents who think ahead to the toddler phase: the rounded posts are specifically designed so a wobbly toddler learning to stand can grip them safely — a functional safety detail, not just a design accent

•       Those building out the Swell collection with the coordinating changing table for a fully cohesive nursery

Not Ideal For

•       Parents seeking a fully neutral or minimal aesthetic: the wavy railings and pop color options are the Swell's signature and define its look — it is not a background piece

•       Buyers who want the full-size bed conversion included: the full-size kit (#M5789) is sold separately; the toddler bed and daybed conversions are included, the full-size is not

•       Very compact rooms: at 54.75"L × 31"W, confirm the footprint works before purchasing

Frequently Asked Questions

What does 4-in-1 mean, and what's included vs. sold separately?

The Swell converts through four configurations: standard crib, toddler bed, daybed, and full-size bed. The toddler bed conversion kit is included in the box — no additional purchase needed for the crib, toddler bed, or daybed stages. The full-size bed conversion kit (#M5789) is sold separately for when the time comes.

What makes the Swell specifically good for shorter parents?

The front rail to floor height is 31" — lower than most full-size cribs in this category. For shorter parents who have struggled to reach comfortably over a taller crib rail during the newborn phase, the difference is genuinely felt on every placement and pickup. The Swell's low-profile design is explicitly built with this ergonomic reality in mind.

Why do the rounded posts matter for toddler safety?

The Swell's posts are specifically rounded to give wobbly toddlers learning to pull up and stand a safe, grippable surface. This is a deliberate structural safety decision — rounded posts are easier and safer for small hands to hold than squared or angular ones during the transition phase between lying down and walking. It's the same thinking behind the Gelato's rounded posts, and it matters most in months ten through eighteen.

What mattress does it take?

Standard crib size: 52" × 27.75". Babyletto recommends Pure by Babyletto crib mattresses. Ask us what we currently carry.

How many mattress height positions are there?

Four adjustable positions. The low-profile design makes placement easy at the highest position for a newborn. Lower the mattress as your baby learns to sit, pull up, and stand to maintain safe rail height at each stage.

How does the Swell compare to the Gelato? Both are 4-in-1.

Both convert from crib through full-size bed with the toddler kit included and the full-size kit sold separately (#M5789). The difference is personality. The Gelato has special (and changeable) feet and a warmer, more sophisticated. The Swell has wave-form railings, pop color options, and an explicitly playful personality inspired by the California coast. If the room is meant to feel grown-up and refined, Gelato. If it's meant to feel joyful, Swell.

Why does my stained-finish Swell look slightly different from the one pictured?

Natural wood grain variation in the New Zealand pine means every stained-finish Swell is genuinely one-of-a-kind. The tones and grain patterns are individual to your piece — this is intentional and a feature of the design, not a defect.

Is it GREENGUARD Gold certified?

Yes. Tested for over 10,000 chemical emissions and VOCs — one of the most rigorous indoor air quality certifications available for a room where a baby sleeps.

Can I see it in person at Babesta?

Floor inventory changes frequently. Contact our Tribeca store at 56 Warren Street for the most current information on what's on display.

Why Babesta Carries It

We carry cribs with strong design points of view across a range of aesthetics. The Swell occupies a lane none of the others do: genuinely, unapologetically playful. The wave-form railings and pop color options are not subtle — they are the design. For parents who want the nursery to feel joyful rather than merely stylish, the Swell is the answer.

The practical case is strong too. At 44.6 lbs it is the lightest full-size crib we carry — a real advantage for walkup delivery and in-room setup. The 31" front rail height is the lowest in the lineup, which matters meaningfully for shorter parents doing multiple pickups and placements a day. And the full 4-in-1 convertibility path — through full-size bed, not just daybed — means this is a genuine long-term investment, not a crib that gets replaced at the toddler stage.

The rounded posts, the included toddler conversion, the GREENGUARD Gold and FSC® certifications — the fundamentals are exactly where they need to be. The Swell doesn't ask you to choose between a crib that's safe and one that makes you smile when you walk into the nursery. That's the point.
