My daughter has this slide gifted first birthday. She loves them dearly indeed, but dares to nine months later, still not down alone to slip. Before the two-meter-high water slide at the playground she has long no longer afraid. The difference is: The Big Baby slide has very niedige edges and protects - at least appear to - not in front of the lateral fall out. In addition, the children end up bruising the slides painfully on the lower back, inclusive. Therefore, it does not go without a mat underneath. The points for the processing, storage life, the compact dimensions and the fun she prepares my daughter after all. Conclusion: Best suited to soft substrates. On Terrassenplatten landing is definitely too hard.
