The WAVE8R is an injection molded wave slide for residential use. We have made the wave less pronounced so that the slide is not so fast for small children. It is more flexible to withstand the weather and freight companies. There is a stake hole in the bottom of the slide so that it can be staked to the ground to avoid being picked up. The sides are also scalloped. The 8 ft slide fits a 4 ft platform. Top lip is 17.5 in. wide, seat is 13 in. wide, sides are 4.5 in. deep. Bottom is 19.25 in. wide and the base is 10 in. from floor to seat. Weight limit 300 lbs. Specifications. Color: Green. Top Lip Dimension: 17.5 in. wide. Seat Dimension: 13 in. wide.
