5. Setup and Assembly Instructions
Before you begin, ensure you have adequate space and the necessary tools (e.g., screwdriver, Allen wrench, and potentially a drill if your crib's headboard/footboard holes are not pre-drilled all the way through).
- Prepare Your Crib: Disassemble your compatible DaVinci crib by carefully removing the existing side rails. Retain the headboard and footboard, as these will form the ends of your new bed.
- Identify Rail Orientation: The conversion rails have specific ends designed to connect to the headboard and footboard. Ensure you orient them correctly.
- Attach Rails to Headboard: Align one end of a conversion rail with the pre-drilled holes on the headboard of your crib. Insert the provided bolts through the rail and into the headboard, securing them with barrel nuts or other specified hardware. Tighten securely, but do not overtighten.
- Potential Drilling Requirement: Some crib headboards/footboards may have pilot holes that do not go all the way through. If the hardware does not easily pass through, you may need to carefully drill through the existing pilot holes on your headboard and footboard to allow the bolts to pass through and connect to the barrel nuts. Use a drill bit size appropriate for the hardware.
- Attach Rails to Footboard: Repeat the process for the other end of the conversion rails, attaching them to the footboard. Ensure the bed frame is square and stable.
- Install Mattress Support (Sold Separately): This kit provides the side rails only. You will need to purchase and install a separate mattress support system, such as wooden slats or a box spring, to support your mattress. Ensure the chosen support system fits securely within the assembled bed frame.
- Place Mattress: Once the mattress support is in place, carefully position your twin or full-size mattress onto the support.
- Final Check: Before use, double-check all connections to ensure they are tight and secure. Verify the bed is stable and level.

6. Operating Instructions (Usage)
Once assembled, the converted bed functions as a standard twin or full-size bed, depending on the original crib size. It is designed to accommodate a standard twin or full-size mattress and a corresponding box spring or slat system (sold separately).
- Ensure the mattress is properly seated on the support system.
- Regularly inspect the bed for any loose hardware or signs of wear.
- Do not allow jumping on the bed, as this can stress the frame and connections.

7. Maintenance and Care
- Cleaning: Wipe the wooden surfaces with a damp cloth. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish.
- Inspection: Periodically inspect all hardware and structural components for tightness, wear, or damage. Re-tighten any loose bolts.
- Storage: If disassembling for storage, keep all hardware in a secure bag and store the rails in a dry, temperature-controlled environment to prevent warping or damage.
8. Troubleshooting
- Rails do not align with crib ends: Double-check that your crib model is listed in the compatibility section. Ensure the rails are oriented correctly.
- Hardware does not fit or go through holes: Verify you are using the correct hardware for each connection. Some crib headboards/footboards may require drilling through existing pilot holes to allow bolts to pass through completely (refer to Section 5, Step 4).
- Bed feels unstable: Ensure all bolts are securely tightened. Check that the bed frame is square. Verify that the mattress support (slats or box spring) is properly installed and provides adequate stability.
- Missing or damaged parts: Do not attempt to use the kit with missing or damaged parts. Contact DaVinci customer support for assistance.
