Spinning play is fun for children of all ages and it plays an important role in their development. Spinning enhances postural control and improves comprehension of speed and movement in relation to your own body. The Whirlwind seat is a simple, fun and inexpensive way to bring all of the benefits of spinning play to your playground. The rotationally-molded plastic seat is ergonomically-designed so that children may sit upright and use the slightly-upturned sides as handgrips, sit as if in a saddle, or lay across on their stomachs. No matter how you choose to sit, the fully-enclosed spinning mechanism delivers a smooth ride every time.
