The Leander Classic Junior Kit extends your baby crib to a toddler bed, letting your child stay in familiar surroundings. Learn how to decide if this conversion is right for you.
Quick answer
The Leander Classic Junior Kit is a practical conversion set that extends your Leander Classic™ baby crib from 120 cm to 150 cm, creating an open toddler bed your child can climb in and out of independently.
Why extend instead of buying a new bed?
Keeping your child in a familiar sleep environment during the transition from crib to toddler bed can ease anxiety and improve sleep quality. The junior kit lets you reuse the same frame and mattress base, saving money and reducing waste compared to purchasing a completely separate toddler bed.
The conversion also maintains the same mattress support height, which can be reassuring for parents who have already dialed in the perfect setup.
What the kit includes and what it doesn't
The junior kit contains the necessary hardware and side panels to extend the crib length and create an open entry. It does not include a new mattress or bedding. You will need to ensure your existing mattress fits the new 150 cm length, or purchase a compatible toddler mattress separately.
The kit is designed specifically for the Leander Classic™ crib frame, so it will not work with other crib models or brands.
How to decide if the junior kit is right for you
- Your child is ready for a toddler bed: If your toddler is climbing out of the crib or showing interest in a bed without rails, the junior kit provides a safe, gradual transition.
- You want to keep the same crib frame: The kit is designed exclusively for the Leander Classic™ crib. If you already own that frame, this is the most cost-effective way to extend its use.
- You need a longer sleep surface: The extension adds 30 cm of length, accommodating a growing child comfortably for several more years. Measure your current mattress to confirm it will fit the new 150 cm length, or plan to purchase a compatible toddler mattress.
- You prefer a fully enclosed crib longer: The junior kit removes the front rail, creating an open bed. If you want to keep a fully enclosed crib for safety or sleep habits, consider delaying the conversion.
