I bought the 44" Bellicon for my son 9th birthday several months ago. He is on the spectrum and must move throughout the day to fulfill his sensory/motor needs. I researched many other brands before picking Bellicon and I am so glad I chose this one! My son loves it so much that it stayed in the living room right where he opened it. He uses it several times a day and we have seen a remarkable improvement in his behavior and regulation, not the least of which is an end to jumping on the couch! Bellicon is a product of unmatched quality, incredibly safe and sturdy, no other brand comes close. My son loves the feeling of the stretchy inner mat and the smooth bounce that the bungee cords provide. We can sit right next to him and talk to him while he jumps because it is so quiet. It's so much fun that his older brother uses it almost as much and everyone who comes over wants to try it out. Thank you Bellicon for exceeding our expectations!
