The play tunnel is heavy and solid, so there is no chance of it flipping over, yet it doesn't need to be anchored to the ground. Its design and weight are sufficient to keep it in place. However, with a bit of teamwork between adults, it can be easily moved to other areas of the playground Children will love testing their physical abilities as they scramble over and tunnel under this exciting play tunnel, suitable for all ages and abilities. Its a fantastic investment piece that looks great and will bring joy to children for years to come.
