Learn how to convert your Leander Classic baby crib into a toddler bed using the Leander Junior Kit. Step-by-step guide with tips for a smooth transition.
Quick answer
Use the Leander Junior Kit to extend your Leander Classic crib from 120 cm to 150 cm and remove the front rail, creating an open toddler bed your child can climb in and out of independently.
Why convert to a junior bed?
The Leander Classic crib is designed to grow with your child. When your toddler is ready to transition out of the crib, the Junior Kit lets them stay in the same familiar bed frame, which can ease the change and save you from buying a separate toddler bed.
The conversion removes the front rail and extends the sleeping surface, giving your child more room and the freedom to get in and out on their own. It's a practical upgrade that maintains the clean look of the Leander Classic.
What you need to know before starting
The Junior Kit is designed specifically for the Leander Classic crib. It includes the necessary hardware and side panels to extend the bed. You do not need any additional tools beyond a standard screwdriver and an Allen key (usually included with the crib).
The conversion is reversible, so you can switch back to the crib configuration if needed. However, once you remove the front rail, the bed becomes an open junior bed, so ensure your child is ready for that change.
How to convert your Leander Classic crib to a toddler bed
- Remove the mattress and bedding: Take out the mattress, sheets, and any bumpers or toys. You need clear access to the crib frame. Check that the crib is on a level, stable surface. A common mistake is leaving bedding inside, which can get caught during disassembly. Always strip the bed completely first.
- Detach the front rail: Locate the screws or bolts securing the front rail to the crib sides. Use the appropriate screwdriver or Allen key to remove them. Keep the hardware in a safe place if you plan to revert later. Label or photograph the hardware layout before removing anything. This helps if you need to reassemble the crib later.
- Install the Junior Kit extension panels: Attach the extension panels to the crib sides using the provided hardware. The panels slide into the existing slots and are secured with screws. Ensure they are flush with the side rails. Do not overtighten the screws; the panels should be snug but not forced. Over-tightening can strip the threads or crack the wood.
- Reattach the side rails and secure the bed: With the extension panels in place, reattach any side rails that were removed. Double-check all connections are tight and the bed frame is stable. The sleeping surface should now be 150 cm long. A common mistake is forgetting to tighten all screws evenly. A wobbly frame can be unsafe for a toddler. Test stability by gently shaking the bed.
- Add the mattress and bedding: Place the mattress back onto the extended frame. The original crib mattress should fit the new length. Add fitted sheets and any toddler-safe bedding. Ensure there are no gaps between the mattress and the frame. Check that the mattress sits flat and does not slide. If the mattress is too small for the new length, consider a mattress extender or a larger toddler mattress.
- Introduce your child to the new bed: Show your toddler their new open bed. Explain that they can now get in and out by themselves. Keep the room safe with a baby gate at the door if needed. Consider adding a bed rail on the open side for extra security. Some children need a few days to adjust. Be patient and offer reassurance. A consistent bedtime routine helps the transition.
