9 Best Crib Conversion Kits (October 2026)

On this page (6 sections)
The best crib conversion kit is the one made for your exact crib model and the bed size you want. For select compatible cribs, DaVinci's hidden hardware rails offer twin or full-size conversion paths; for a toddler bed, choose a model-specific rail such as NAMESAKE's Abigail and Winston kit.
Crib conversion kits are not interchangeable by default. Compare compatible crib replacement hardware kits before ordering parts.
A rail that looks close may have different attachment points, slat lengths or hardware, so start with the label on your crib and its manual.
Our scores weigh the stated fit, included parts and conversion type against what you're shopping for. The product names and models below are specific; use the crib manual to confirm the right rail before assembly.

How we compared crib conversion kit types
The best crib conversion kit depends first on model compatibility, then on whether you want a toddler bed, twin bed or full-size bed. We compared the conversion paths and fit details given for each option.
A toddler rail is for a compatible crib that converts to a toddler bed, while a full-size rail set supports a larger bed conversion for select cribs. Some convertible cribs may support more than one stage, but the kit must match the exact crib model and instructions.

The best crib conversion kits by fit and conversion type
These crib conversion kits serve different crib families and bed sizes, so the best choice for you is the one whose compatibility details match your crib. Check the model number and manual before selecting a kit.
The DaVinci Hidden Hardware kit stands out for buyers who need a twin or full-size conversion rail set. It supports converting a full-size crib to a full-size bed or a mini crib to a twin bed, so the intended conversion depends on the crib size you own.
DaVinci specifies compatible models across select Babyletto, Babymod, Carter's by DaVinci, DaVinci and Million Dollar Baby Classic cribs. For a Hudson crib, see Babyletto Hudson hardware replacement.
The set is made from sustainable New Zealand pine wood and has a non-toxic, multi-step finish described as lead and phthalate safe.
A mattress and box spring are sold separately. Before choosing a crib conversion kit for a full bed, check that your crib is full-size and that its model appears in the compatible group.
Davinci Toddler Bed Conversion Kit: Best for a DaVinci classic crib
- For converting a full-size classic crib to a toddler bed
- Model M3099Q
- Package dimensions 53 x 15 x 2 in
A toddler-bed option for a compatible full-size classic crib. Confirm that the model matches your crib before ordering.
Pros
- Conversion type is stated
- Model number is provided
Cons
- Compatibility with specific crib models needs confirmation
This DaVinci kit is for converting a full-size classic crib into a toddler bed. Its model number is M3099Q, so use that number to compare with your crib manual rather than assuming it fits every DaVinci crib.
The kit is a narrower choice than a twin or full-size bed rail set because it serves the toddler-bed stage. The available fit details do not name the compatible crib models, so confirm the exact match with DaVinci before you order.
If your crib is from Storkcraft, use a guide to the best Storkcraft crib conversion kit to check the brand-specific options. A conversion kit for a different manufacturer may not attach correctly.
CC KITS Full-Size Wood Conversion Kit Bed Rails: Best for named Baby Cache cribs
- For select Baby Cache cribs with 54 in slats
- Solid wood rails
- Four 54 in slats, hardware and instructions
- Some compatible models are expressly excluded
A full-size bed conversion option for the listed Baby Cache models with 54 in slats. Check both the model name and the fit guide exclusions.
Pros
- Detailed model compatibility guide
- Rails, slats, hardware and instructions included
Cons
- Does not fit several named Baby Cache models
- Additional slats are sold separately for the stated weight support
This CC KITS set is designed for named Baby Cache cribs with 54 in slats and converts the crib to a full-size bed. It includes two solid wood rails, four slats, hardware and instructions.
The compatibility guide names many models and also excludes Cape Cod, Hudson, Portland, Tahoe and Uptown. Check the exact model and finish against the guide, and note that additional slats are sold separately for the stated 600 lb support capacity.
This is a fit-specific alternative to a Delta Children crib conversion kit or another brand's rail set. Do not choose by appearance alone, since the attachment and slat details are part of the fit.
NAMESAKE Abigail and Winston Toddler Bed Conversion: Best for Abigail or Winston cribs
- Fits Abigail 3-in-1 crib M15501 and Winston 4-in-1 crib M15301
- Iron
- GREENGUARD GOLD Certified
This toddler rail is specific to two named NAMESAKE crib models. Check the model number on your crib before selecting it.
Pros
- Two compatible models are named
- GREENGUARD GOLD Certified
Cons
- Limited to the named Abigail and Winston models
The NAMESAKE Abigail and Winston kit converts two named cribs to toddler beds: the Abigail 3-in-1, model M15501, and Winston 4-in-1, model M15301. It is made from iron and is GREENGUARD GOLD Certified.
This option is useful when you have one of those exact crib models and want a toddler rail. It is not a general toddler rail for other NAMESAKE or DaVinci cribs, so check the model label carefully.
For another brand-specific fit check, compare with a Graco crib conversion kit only if your crib is a Graco model. A crib's brand and model determine which kit to investigate.
Sorelle Furniture Toddler Rails and Full-Size Bed: Best for Sorelle rail choices
- Toddler rail and adult rail options
- Rail choice depends on crib model and manual
- Espresso finish shown
Sorelle offers toddler and adult rail options, with compatibility tied to the crib and its manual. Match the rail number, finish and conversion type to your crib.
Pros
- Toddler and adult rail paths are described
- Several compatible crib families are named
Cons
- Not every crib supports both conversion types
- Exact rail choice depends on the crib manual
Sorelle offers toddler and adult rail options, but the correct rail number, finish and conversion type depend on the crib and its manual. The product information names compatible Sorelle families for the toddler rail and says some cribs can also use an adult rail.
The rail is wood, and this option is shown in espresso. Sorelle also offers other colors, so check the finish alongside the rail number when you compare it with your crib instructions.
If you own a Pottery Barn crib, start with the guide to a Pottery Barn crib conversion kit for model-specific options. A Sorelle rail should not be treated as a substitute.
Soho Baby Chandler Crib to Toddler Bed: Best for the Chandler 4-in-1 crib
- Fits Soho Baby Chandler 4-in-1 crib 44011530
- Guard rail can go on the right or left
- Hardware included
- GREENGUARD GOLD Certified
This rail is designed for the Chandler 4-in-1 crib, with a choice of right or left placement. Confirm the crib model before ordering.
Pros
- Compatible crib model is named
- Right or left placement
- Hardware included
Cons
- Fits the Chandler model only
The Soho Baby Chandler rail fits the Chandler 4-in-1 Convertible Crib, model 44011530, and converts it to a toddler bed. It can be placed on the right or left side, and hardware is included.
Soho Baby says the rail is made from solid woods and wood veneers, is GREENGUARD GOLD Certified, and carries a 1-year limited manufacturer’s warranty. Keep the model number handy when checking compatibility.
For a crib-to-toddler change, compare this with a crib-to-toddler-bed conversion kit that matches your own crib brand and model. Toddler rails are not universal just because they serve the same stage.
CC KITS Full-Size Conversion Kit Bed Rails: Best for named Oxford Baby, Soho or Ozlo cribs
- Hook-on and bolt-on fit guides
- Named Oxford Baby, Soho and Ozlo models
- Four slats, hardware and instructions
This kit has separate hook-on and bolt-on compatibility guides for select cribs. Match the crib model and rail type to the correct guide.
Pros
- Separate fit guides for two attachment types
- Many compatible models are named
Cons
- Several crib models are excluded
- Fit depends on rail type and slat length
This CC KITS full-size conversion set has separate hook-on and bolt-on fit guides for select Oxford Baby, Soho and Ozlo cribs. The hook-on guide gives a 53.75 in slat length, while the bolt-on guide gives 54 in.
It includes two wood rails, four slats, hardware and instructions. The guide also excludes several named crib models, so check both the attachment type and the exact crib name before choosing it.
For other model-specific options, compare the best DaVinci crib conversion kits and confirm the rail style against your manual. A brand match alone does not confirm a fit.
dadada Toddler Bed Rail Crib Conversion Kit: Best for select dadada cribs
- Fits Soho, Austin, LaLa and Bliss cribs
- Not compatible with Jolly or Spirit
- Solid beechwood
- GREENGUARD GOLD Certified
A toddler rail for select dadada models, with four compatible models named. It does not fit the Jolly or Spirit crib.
Pros
- Compatible and excluded models are named
- Toddler bed or day bed use
- GREENGUARD GOLD Certified
Cons
- Not compatible with cribs from other brands
The dadada toddler rail is designed for select dadada cribs: Soho, Austin, LaLa and Bliss. It can convert a compatible crib to a toddler bed or day bed, and it does not fit Jolly, Spirit or cribs from other brands.
The rail is made from solid beechwood and is GREENGUARD GOLD Certified. dadada says assembly instructions and online tutorial videos are included, which may help when preparing the conversion.
If you're comparing a Babyletto crib conversion kit, use the exact Babyletto model and its manual to narrow the options. Similar brand families do not guarantee that rails are shared across models.
This DaVinci Babyletto rail set supports the same two conversion paths as the white DaVinci option: a full-size crib to a full-size bed, or a mini crib to a twin bed. It is made from New Zealand pine wood and shown in natural walnut.
The compatible group includes select Babyletto, Babymod, Carter's by DaVinci, DaVinci and NAMESAKE cribs. The mattress and box spring are separate, so include them in your plan if you are converting to a larger bed.
For other rail styles, see our guide to the best convertible crib rail and best crib toddler rail. The compatibility guide still needs to match your specific crib.
How to check whether a conversion kit fits your crib
Check the crib's model number, rail type and manual before buying a conversion kit. The manufacturer’s guide should match the model you own and the bed stage you plan to use.
Start with the model label on the crib or the paperwork from its original assembly. If you have a hand-me-down crib, ask the previous owner for the manual or search the brand’s support pages using the model number.
Then compare the kit details, including:
- Exact crib brand and model
- Toddler, twin or full-size conversion type
- Hook-on or bolt-on attachment, if specified
- Slat length, if the guide gives one
- Required hardware and parts
- Finish or rail number, where options vary
If the model is not named, contact the crib maker before ordering. Do not assume a universal crib conversion kit will fit because the rails appear to be the right length.
Should you choose a toddler rail or a full-size bed kit?
Choose a toddler rail when your compatible crib is intended to become a toddler bed. Choose full-size rails when the crib model supports a larger bed conversion and you have room for the bed and its separate components.
A toddler rail serves a different purpose from a full-size bed frame kit. For example, the NAMESAKE rail is for two named toddler-bed conversions, while DaVinci's hidden hardware rails support twin or full-size conversions for select models.
Check whether your crib manual gives a conversion sequence or specific parts for each stage. If you are deciding between brands, a toddler rail for a Graco Hadley crib or Dream On Me bed rails guide may help narrow the search by crib family.
What should you confirm before assembly?
Confirm the kit matches your crib and follow the crib and kit instructions during assembly. Use the specified hardware and parts, and stop if the pieces do not align as shown in the manual.
If you also need a replacement mattress support, see our crib mattress support frame guide.
Keep the instructions with the crib parts so you can check the correct rail orientation and fastening steps. For a full-size conversion, verify which mattress and box spring are required and whether they are sold separately.
After assembly, check that the bed is stable and that all fasteners are installed as directed. Contact the crib maker if a part is missing or the fit differs from the instructions.
Which crib conversion kit should you choose?
Choose the DaVinci Hidden Hardware kit if your select crib is compatible and you want a twin or full-size conversion. Choose a toddler rail such as the NAMESAKE or Soho Baby option only when its exact crib model matches yours.
For Baby Cache, Oxford Baby, Soho or Ozlo full-size conversions, compare the CC KITS fit guide with your crib's attachment style and model. The right crib conversion kit is the one that matches the manual, model and next bed stage.

Frequently asked questions
Are crib conversion kits universal?
No. A crib conversion kit usually fits specific brands or models, and some kits also depend on the rail attachment style or slat length.
Check the crib's model label and manual, then compare those details with the kit's compatibility guide before buying.
How do I know which conversion kit fits my crib?
Find the crib's brand and model number on its label or in its manual. Compare both with the kit's compatibility details, including rail type and any stated slat length.
If the exact model is not named, contact the crib maker before ordering.
Do crib conversion kits include a mattress?
Not always. DaVinci's twin and full-size conversion rails require a separate mattress and box spring.
Check what's included for the exact kit and conversion stage, since toddler rails and full-size bed rails serve different purposes.
What is the difference between a toddler rail and a full-size conversion kit?
A toddler rail helps convert a compatible crib into a toddler bed. A full-size conversion kit uses rails to turn a compatible crib frame into a larger bed.
Choose based on the next bed size you need and the conversion options your crib supports.
Can I use a universal crib conversion kit?
Treat a universal crib conversion kit as a claim to verify, not proof that it fits every crib. Attachment points, rail type and slat length can differ by model.
Match the kit to your crib's exact model and manual before using it.
