The ECR4Kids Quad Seesaw is a traditional seesaw with the added fun of up to four riders. Intended for ages 3+, maximum total weight 220lbs. Constructed with heavy-duty steel pipe, this simple but stylish seesaw is extraordinarily stable. Powder coating makes it weather-proof and great for indoors or out. The stopper pole under each seat reduces the shock to let children get down softly and smoothly. Seats are designed to support children for a safe and comfortable ride, while easy-to-grip handles ensure little hands will be able to hold tight while they play. For safe use, the center axis must be anchored into concrete or buried concrete blocks. The blocks of concrete should not stand out from the ground, to avoid any trips or falls. Hardware is included. Fade- and Weather-Resistant plastic and powder coated steel frame is built to withstand the elements and extended use, whether placed indoors or outdoors. Product dimensions: 94in (L) x 23.6in (W) x 38.2in (H).
