Operating Instructions: Adjustable Mattress Heights
The daVinci Union Crib features four adjustable mattress heights to adapt to your child's developmental stages. Adjusting the mattress height is crucial for safety and convenience.
- Highest Position: For newborns and infants who cannot push up on their hands and knees. This position allows easier access to your baby.
- Mid-High Position: For infants who are beginning to sit up unassisted.
- Mid-Low Position: For infants who are beginning to pull themselves to a standing position.
- Lowest Position: For toddlers who can stand. This is the safest position to prevent climbing out.
To adjust the mattress height, carefully remove the mattress support from the crib frame, reposition the support brackets to the desired height, and re-secure the mattress support. Always ensure all fasteners are tightened securely after adjustment.
Conversion Instructions
The daVinci Union Crib is designed to convert into a toddler bed, daybed, and full-size bed. Conversion kits are sold separately.
1. Toddler Bed Conversion
To convert the crib to a toddler bed, you will need the Toddler Kit (Model No. M3899, sold separately). This conversion replaces one side of the crib with a low safety rail, allowing your child to get in and out independently while providing a barrier against rolling out.


2. Daybed Conversion
The daybed conversion typically involves removing one side of the crib entirely, creating an open-front sleeping or lounging space. This conversion often uses the same components as the crib, without the need for additional kits.

3. Full-Size Bed Conversion
To convert the crib to a full-size bed, you will need the Full-Size Kit (Model No. M4799) and a Full-Size Bunkie Board (Model No. M26058B), both sold separately. This conversion utilizes the headboard and footboard from the crib to form a full-size bed frame.

Refer to the specific instructions included with each conversion kit for detailed assembly steps.
Care and Maintenance
- Cleaning: Wipe the crib surfaces with a damp cloth. Avoid using abrasive cleaners or strong chemicals, as these can damage the finish.
- Inspection: Regularly check all screws, bolts, and fasteners to ensure they are tight and secure. Periodically inspect the crib for any signs of damage or wear.
- Storage: If storing the crib, ensure it is clean and dry. Store in a climate-controlled environment to prevent warping or damage to the wood.
