Wiwiurka's triangular rope climber/ladder is equipment designed for children to strengthen their gross motor skills as climbing helps them strengthening their arms and legs, eye-hand coordination and balance, among other skills. 
It is important to mention that physical movement at an early age is a foundation for reading-writing and analytical thinking.

Enjoy watching your child(ren) and their friends using this fantastic climbing structure. Children can also swing, twirl and do acrobatics with it. Besides strengthening their gross motor skills, your children can also let their imagination go: "Look, mom, I'm taking off in the spaceship!"
