Love my new Jumpsport 550f PRO! Followed directions for one-person assembly, including removal of every other bungee from its saddle (to lesson tension in order to open the folded frame.) I still could not open it, so I removed 2/3 of bungees (symmetrically), which created enough slack to open the folded frame. Then I secured the frame open (hinges shut) and "restrung" the loose bungees back in their saddles. Pro tip: leave the bungees intact if they tunnel through the mat loops (as these are harder to re-string.) I am 5'5", 100 lbs. If I can do it, you probably can, too! You will love bouncing on your Jumpsport and enjoying health benefits including better balance and more energy!

BUY IT

This is such a wonderful upgrade to an old spring very small rebounder (24" wide jump space ) that I had been using for about two months. It basically had no bounce. It was sitting unused. Was given to me by a neighbor years ago. Then I got interested in rebounding again after joining a few Facebook Rebounding groups. I did a lot of research before purchasing this rebounder and this particular size. What a wonderful jump experience I am having. It is so much easier on my body. I feel much more confident on the larger mat which is a 31" jump space. More room to move my legs in all positions. On my smaller one I was hesitant to move much for fear of jumping on the springs. This is a quality rebounder. Very sturdy, was easy to put together. I watched a youtube that helped with that process. I am 67.5 inches tall, 137 lbs. Have size 10.5" feet. 69 years old. I am very active and highly recommend this rebounder. I have not changed the bungees as I have only been jumping on this for a few weeks. I know in time I will change them to see what other type of bounce I can get. This was one of the reasons I wanted to purchase a rebounder with bungees so I could change them up. I don't plan on folding this down. I purchased the folding unit because it was $100 cheaper than the 550PRO which a representative from JumpSport told me they are the same units except it is cheaper to ship the folding unit. The wall behind the JS in the picture is 42.5 ".

Very sturdy - easy to assemble
