The Mad Dash Value 10ft Trampoline and Enclosure does not have any welds on the trampoline giving increased strength with their patented weld free T-Section which attaches to the legs of the main frame. This also allows for a quicker assembly time. The whole frame is manufactured from high quality steel and galvanised inside and outside. All springs are galvanised. This trampoline is ideal for you or your family. The spring cover is 26cm and covers the springs so that they are not exposed.
