- Take the playground experience to the next level with the Rockwell Teeter Quad. This play element can hold up to four children ages 2-5, and is made of high-quality galvanized steel. This teeter is a reimagining of the classic seesaw, with elements from a spring bouncer. This prevents the seats from ever rising too high from the ground, making this piece of equipment perfect for preschool age children. Additionally, steel rings are attached in front of the seats, one for the feet and one for gripping. Aside from being pure fun, the Quad Teeter Totter also encourages kids to play cooperatively, a vital lesson to learn for the proper development of children.
