Question: Can you add a stability bar to this mini trampoline?   Thanks!
Document: I am enjoying my ReboundAir mini-trampoline. I have used it almost everyday since  I purchased it. I compared it to an older mini-trampoline my  wife had bought at a yard sale a few years ago and it was no comparison. The yard sale model was so much lighter and the workmanship was poorly lacking.
I bought my ReboundAir for my joints. I use it consistently, 20-30 minutes 3x weekly for over a year, because it's fun and energizing. I lift weights for muscle and bone strength. I use my trampoline to energize and for bone strength also. Walking, bending and climbing stairs is easier. NASA has approved this form of exercise for their astronauts. ReboundAir is the best mini trampoline on the market.The quality is excellent.
there is a soft bounce to it , and it makes you feel like jumping on it. I use it almost every day. The other trampoline I had was kind of stiff
I got such a good deal on this half fold trampoline I couldn't believe it. It is so much fun! My small children, 7 & 4 love it too! We keep it in the living room and every time they go near it they get on and start jumping! It is a bit heavy to carry by myself, so when we have to move it I just have my husband do it. ;) I would definitely recommend this trampoline. Great product, great company!
After reading references to the  benefit of rebounding for physical well being in several unrelated articles my curiosity was peaked. A specific search for rebounding and its benefits brought me to the conclusion that this was something I wanted to experience. I set out to research the matter. My search lead me to two products for consideration. Online I investigated product details and read testimonials for each version of mini trampolines. Ultimately I decided on and purchased the ReboundAIR.
Wow what difference!! I have been using a $20 rebounder from Walmart and I decided to purchase a more expensive rebounder and what a difference. First time on you really notice a difference in bouncing. Very pleased and well worth the extra money!
We've lost lights and an LCD monitor. Second, the frames break at the legs. Yes, I wrote &#34;frames&#34; ! After much fighting with the company, we were able to get a new and cheaper frame than the first. (Their &#34;aircraft grade&#34; plastic has now given me new concerns about flying!)
To my knowledge, no one makes a unit like that. But if this company simply made a 6-foot version of the industry-standard 4-foot unit, I'd buy it.Best of all, this thing is fun to bounce on. At last, I have a way to get aerobic exercise that I enjoy. And my legs and calves are getting stronger as my aerobic capacity increases.
This product is terrible and the service is even worse.Our 17 year-old (150 lbs) needs to use this product daily. He has aspergers syndrome and finds emotional relief from the day in jumping. There's nothing abnormal or destructive about his jumping. He simply uses the product a lot.We bought their premium product with a &#34;Life Time&#34; guarantee. It has not held up.
This is an obviously well-made rebounder. My kids bounce on it like crazy and I bounce very gently. It has held up very well. The folks at Reboundair are also very nice if you have a question.
Answer: yes
