The Kullerbu Play Track System

There's no right or wrong way to build a Kullerbu track - just mix creativity with the high-quality pieces and you'll be amazed at the results.

Easy assembly means little builders don't have to wait long to start playing. If the track layout doesn't work perfectly the first time, it's simple to rebuild. Kullerbu track layouts can be a new experience each time.

Kullerbu layouts are also sold and stable. They will stay together even if the little builder should happen to bump into them. That keeps the focus on creating and expanding this fun play world.
