Just spent 2 1/2 hrs putting a 4 foot trampoline together for my great grand daughter. What a royal pain in the butt. Think I would rather change a couple Valkyrie alternators, would be easier. It gets assembled folded, then have to flatten it and put bolts in to keep it there. Took my wife and me standing on one side to hold it down, then put the bolts in with out letting it fold back up. Has a whole bunch of tension on the mat.
