6 Best DaVinci Crib Conversion Kits (November 2026)
The best DaVinci crib conversion kits include the Davinci Toddler Bed Conversion Kit for a classic full-size crib, the Davinci Toddler Bed Conversion Kit for Charlie, Grove, Liam, or Nathan, and the DaVinci Hidden Hardware Twin/Full-Size Bed Conversion Kit for twin or full-size bed stages.
On this page (4 sections)
The best DaVinci crib conversion kit depends on your crib model and the bed stage you need. The M12599 names four compatible models, while other kits fit specific collections or select mini cribs.
A conversion kit can make a crib useful through a later bed stage, but compatibility comes first. Start with your crib's model number, then match it to the kit before comparing wood, finish, or bed size.
If you are new to conversion options, our guide to what exactly is a crib that turns into a bed for new parents explains how the stages differ. For a wider look at brands and kit types, see our best crib conversion kit roundup.

Which DaVinci crib conversion kits fit specific needs?
The strongest choice depends on whether you need toddler rails, a twin conversion, or a full-size bed conversion. Among these picks, the highest-scoring option is the M3099 toddler kit for a full-size classic crib, while the M12599 gives the clearest model list.
Davinci Toddler Bed Conversion Kit: Best for a classic full-size crib
- M3099Q model number
- Converts a full-size classic crib to a toddler bed
A toddler-bed option for a full-size classic crib. Confirm that your crib matches the M3099 kit before choosing it.
Pros
- Identified for a full-size classic crib
- Toddler-bed conversion
Cons
- Compatible crib models are not named
The M3099Q kit is described for converting a full-size classic crib into a toddler bed. DaVinci also describes wooden bed rails for converting a crib into a full-size bed, so confirm the intended configuration for your crib before ordering.
The product name identifies the M3099Q model, but it does not name compatible crib collections. Check your crib's model label and manual, then confirm that the M3099 kit matches before you buy.
Choose this option if you have a full-size classic crib and need toddler-bed rails. If you cannot verify the model match, ask DaVinci to confirm compatibility.
Davinci Toddler Bed Conversion Kit: Best for Charlie, Grove, Liam, or Nathan
- Compatible with Charlie, Grove, Liam, and Nathan cribs
- New Zealand pine wood
- Non-toxic multi-step finish
This toddler-bed kit names four compatible DaVinci crib models, making it easier to check fit by collection.
Pros
- Four compatible crib models are named
- Made of New Zealand pine wood
Cons
- Only toddler-bed conversion is described
The M12599 is the clearest fit for owners of a Charlie, Grove, Liam, or Nathan crib. Those four models are named as compatible, and the kit converts a full-size crib into a toddler bed.
It is made of sustainable New Zealand pine wood and has a non-toxic multi-step finish described as lead and phthalate safe. Those details may help narrow a choice when the compatible model list already matches your crib.
Choose it when your crib is one of the four named models and you want a toddler-bed conversion. For Charlie-specific fit guidance, read which conversion kit fits a DaVinci Charlie crib.
The M5789 supports two configurations: a full-size bed from a full-size crib, or a twin bed from a mini crib. It is compatible with select Babyletto, Babymod, Carter's by DaVinci, DaVinci, and Million Dollar Baby Classic cribs.
The twin or full-size mattress and box spring are sold separately. Confirm your crib model against the compatible models for this kit, and budget for the bed components needed for your chosen stage.
Choose it when a larger bed conversion is your goal and your crib is supported. The two stage options make it different from the toddler-bed kits in this roundup.
DaVinci Jenny Lind Toddler Bed Conversion Kit: Best for a Jenny Lind crib
- Designed for a Jenny Lind crib
- New Zealand pine wood
- Non-toxic multi-step finish
- 1-year warranty
A collection-specific toddler-bed kit for the Jenny Lind crib, with a stated 1-year warranty.
Pros
- Named for the Jenny Lind crib
- Warranty term is stated
Cons
- Only toddler-bed conversion is described
The M3199 is made for converting a Jenny Lind crib into a toddler bed. Its collection-specific name makes it a straightforward candidate if you own a Jenny Lind crib, but it does not guarantee fit for other DaVinci models.
The kit is made from sustainable New Zealand pine wood and has a non-toxic multi-step finish described as lead and phthalate safe. DaVinci also states a 1-year warranty.
Choose this kit when you have a Jenny Lind crib and want the toddler stage. If you are unsure which version of your crib you own, compare its model number with the manual before ordering.
Davinci Union Toddler Bed Conversion Kit: Best for the Union crib
- Compatible with Union crib M3801
- New Zealand pine wood
- Non-toxic multi-step finish
This toddler-bed kit names the Union M3801 as its compatible crib, so it suits shoppers who have that specific model.
Pros
- Compatible crib model is named
- Toddler-bed conversion
Cons
- Compatibility is limited to the named Union model
The M3899 is the Union collection pick, with compatibility named for the Union M3801 crib. It converts a full-size crib into a toddler bed, so the model match and stage are both specific.
The kit is made of sustainable New Zealand pine wood and has a non-toxic multi-step finish described as lead and phthalate safe. DaVinci also says it meets ASTM International and U.S.
CPSC safety standards.
Choose this option if you have the Union M3801 and need toddler-bed rails. For a crib from another collection, use that model's own compatibility information instead.
Davinci Mini Toddler Bed Conversion Kit: Best for select DaVinci mini cribs
- For select DaVinci mini cribs
- New Zealand pine wood
- Non-toxic multi-step finish
A toddler-bed conversion option for select DaVinci mini cribs. Confirm your exact mini crib model is supported.
Pros
- Made for mini crib conversion
- Material and finish are stated
Cons
- Compatible models are not named
The M20399 converts a select DaVinci mini crib into a toddler bed. That makes it the mini crib option here, but the compatible models are not named.
The kit is made of sustainable New Zealand pine wood and has a non-toxic multi-step finish described as lead and phthalate safe. Since the model list is not specified here, match your mini crib's model number with DaVinci before choosing it.
Choose this kit if you have a DaVinci mini crib and want the toddler stage. If you need a twin bed instead, compare the mini-to-twin option in the M5789 kit and confirm your crib is compatible.
How should you choose a DaVinci crib conversion kit?
Choose by crib model first, then by the bed stage you want. A kit that fits one DaVinci collection may not fit another, even when both cribs convert to the same stage.
| Product | Best for | Our score |
|---|---|---|
| Davinci Toddler Bed Conversion Kit | a classic full-size crib | 9.7 |
| Davinci Toddler Bed Conversion Kit | Charlie, Grove, Liam, or Nathan | 9.6 |
| DaVinci Hidden Hardware Twin/Full-Size Bed Conversion Kit | twin or full-size bed stages | 9.3 |
| DaVinci Jenny Lind Toddler Bed Conversion Kit | a Jenny Lind crib | 9.0 |
| Davinci Union Toddler Bed Conversion Kit | the Union crib | 8.8 |
| Davinci Mini Toddler Bed Conversion Kit | select DaVinci mini cribs | 8.5 |
Check the model label on the crib or look in its manual. Match the number or collection name to the kit's compatibility details, and contact DaVinci if the match is unclear.
Next, check the stage. Toddler rails, a twin conversion, and a full-size conversion solve different needs, and the kit descriptions do not make them interchangeable.
For a crib-specific guide, see our DaVinci Roxanne crib conversion kit article. For another collection-specific example, our DaVinci Kalani crib conversion kit guide can help you check the fit question by model.
What should you verify before buying?
Verify the crib model, conversion stage, and any bed components you will need. Those checks help prevent choosing a kit that fits a different collection or leaves you without the required mattress and frame parts.
A toddler conversion kit may be a set of rails for the crib's next stage. A larger bed conversion can need separate components, as with the M5789 kit's separately sold mattress and box spring.
Look for material and finish details only after compatibility is clear. Several picks here specify New Zealand pine wood and a non-toxic multi-step finish, but those shared details do not mean the kits fit the same cribs.
DaVinci also offers conversion kits for other crib brands and collections. Use that broader comparison if your model is not included in the specific compatibility notes here.
Which DaVinci crib conversion kit should you choose?
Choose the M12599 if you have a Charlie, Grove, Liam, or Nathan crib and need toddler rails. Pick the M5789 if you need a twin or full-size bed stage and your crib is among its supported models.
For a collection-specific match, choose the Jenny Lind or Union kit only for the named crib model. For any model not clearly covered, confirm fit with DaVinci before ordering.
If you are still comparing kit styles, start with our guide to the best DaVinci crib conversion kit, then verify your crib model and intended bed stage.

Frequently asked questions
How do I know which DaVinci conversion kit fits my crib?
Match the kit's compatible model name or number to your crib's model label and manual. Some kits name specific collections, such as Union or Jenny Lind, while others say they fit only select DaVinci cribs.
If your crib model is not named, contact DaVinci before ordering.
Can one DaVinci kit convert a crib to both a toddler bed and a full-size bed?
The kits here describe different stages. Most are toddler-bed rails, while the hidden hardware kit supports a full-size bed conversion from a full-size crib or a twin conversion from a mini crib.
Check the stage and crib size in the kit details before buying.
Does a DaVinci full-size bed conversion kit include a mattress?
No. The DaVinci hidden hardware twin/full-size kit notes that the twin or full-size mattress and box spring are sold separately.
Plan for those additional pieces if you are converting a crib to a larger bed.
Can I use a toddler-bed kit with a DaVinci mini crib?
Some kits are made for select DaVinci mini cribs, including the M20399 mini toddler bed kit. Other toddler-bed kits in this guide are described for full-size cribs or named collections.
Confirm your exact model before choosing a kit.
