DaVinci Kalani 4‑in‑1
right at your $250 ceiling
Wirecutter's best-for-most-families pick and the default answer across 9 tested sources — GREENGUARD Gold New Zealand pine, four conversion stages, 10+ finishes.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Every conversion kit is a separate purchase. DaVinci is the category's holdout: the toddler kit (M3099), the full-size kit (M4799) and the bunkie board each run $50-$100, so a Kalani actually taken through all four stages lands close to the $399 Babyletto Hudson — which includes its toddler kit in the box.

■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you need a bassinet for newborn's first 0-6 months only
- you need a portable/travel crib for trips
- you need a smart crib with auto-soothing features only
- you need a convertible car seat or stroller, not nursery furniture
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the DaVinci Kalani 4-in-1 is right for you
It avoids every trap below — and for anyone, under $250, it is the pick because it delivers:
The 4-in-1 that isn't
"4-in-1" almost never means four in the box. The DaVinci Kalani (kits M3099 and M4799), the Jenny Lind (M3199), the Graco Benton (both kits) and the Delta Frankie toddler guardrail (#W100825) all charge $50-$150 extra per stage. Only the Babyletto Yuzu ships every kit it advertises.
No mattress in any box
Not one crib on this list includes a crib mattress — the Yuzu ships bassinet and midi pads only, the Dream On Me a 1-inch pad. Budget separately for a standard 27.25 x 51.625 in mattress, and note a mini crib's ~38 x 24 in size is not interchangeable.
Hand-me-downs and add-ons
Drop-side cribs have been banned since 2011, and the 2022 Safe Sleep for Babies Act bans inclined sleepers and padded crib bumpers — never add either to a compliant crib. Slat spacing must be no more than 2 3/8 inches, and a pre-2011 hand-me-down may meet none of this.
