This slide is not exceptional. It is rather small ... my two year old daughter, sitting up, not down in that one meter. So to 3 years, it will be too small. The mounting system for the pipe does not take with the water pressure, we must put in place every two minutes. The biggest concern remains stable. When children go up the ladder, slide and the wobbles may fall. We must constantly keep an adult therefore not practical at all. In the end, buying inadvisable ... better to invest more and have a slide which can be used longer and more convenient.
