I was worried that assembling would have been hard after seeing other reviews, I had my dad and brother help, turned out not needed, one helper would have been enough, as long as you take your time, and make sure the person opening the trampoline up is strong and does not let go untill you get the bolts started, recomend assembling on a flat hard surface, and before you put in the only 2 bolts that holds the frame together, make sure the two ends are seated flat together.
