Jumpolene

I must admit that we do not have one of these. We have a small indoor trampoline that is about 4 ft which works well for our home.  The nice thing is there is quite a selection if you go this route as well as other things you can add into the jumpolene to give more sensory input.
The reason we do not have one is not due to cost but because when you get a product for a child with sensory needs you need to look at a bigger picture. In our home my son has a habit of breaking any inflatible ball that comes into our home with the exception of exercise balls because of their thickness. For us this probably would have been a wasted investment but for other families whose children don't have a love of popping things this might be well worth the investment.
