We purchased the Propel trampoline a few years ago for our son who has special needs. Our intentions were to use the trampoline for therapy to help with sensory regulation. Our son has autism and has difficulty with hyperactivity and attention deficit issues as well. This trampoline has literally been a lifesaver for our family! Our son uses it daily and it has been a tremendous therapeutic tool. Jumping on the Propel trampoline really helps calm our son and after he has used it for even a very short time, we notice a huge difference in his ability to focus and interact appropriately! Initially I was concerned about the safety of a trampoline but we have found that the enclosure really helps keep children safe while jumping on the trampoline. The enclosure is very well made and sturdy which allows our son to jump quite high and remain safe. I have also been impressed with how well this trampoline has held up. My son has been using the Propel trampoline every day for several years and it is still in great shape! This product is very well made! I highly recommend the Propel trampoline to any family looking for a fun way to get exercise and burn off some extra energy! I can honestly say that we would never be without a trampoline again. My only complaint about this trampoline is the size. Next time I will purchase the bigger Propel trampoline.
