Designed for children ages 2-12, As important as it is for children to swing and slide, it is equally as important that they engage in activities that will help to strengthen developing muscles. The Individual Rubber Balance Post by Child Works will inspire climbing, thereby offering an outlet for the exercises that they need. When placed in a row, children can jump from one to the next allowing them to increase their heart rate, improve coordination, and gain confidence. Regardless of size, these posts have a 10-inch diameter so they offer plenty of room for children to gain safe footing. They are available in 7.5, 11.5, 15.5 and 19.5-inch lengths so you can really be creative with how you place them. Every playground needs an element that promotes exercise and coordination.
