Their particular policy may not allow it. Also let the parent’s know what you want to do, and you’ll have to to check their insurance or try PBC loans (USA). The insurance may allow it but the parents may not want their kids to have it for a variety of reasons.
In that particular video from VBN, the recipients had already promised it to their kids when they were debt free. Your friends may have a different reward in mind such as a special trip or new bikes, or … you get the idea. Your friends choice(s) need to be respected.
I know for us, when our dd was a kid, we would not have allowed a trampoline. Our dd has health concerns but wanted one. We told her to ask her cardiologist and orthopedic surgeon if it was okay and if they gave a thumbs up we would get one. Well I knew they wouldn’t so I could take this gamble. The cardiologist happened to be the first one we saw on the day of appointments. His first words were, “Absolutely not” but not for the reason I thought. He said the American Academy of Pediatrics has deemed them one of the most dangerous “toys” out there, or maybe the one that causes the most injuries. Something like that. Well, dd went on to ask the ortho surg. and he basically echoed what the pediatric cardiologist said for the same reasons. They both said regardless of physical problems in a kid they would not recommend it. (I thought they would not allow it only on the basis of her physical problems.)
I am not saying no kid should have one because it’s up to the parents. I don’t want to debate trampolines specifically. I am just passing on what we learned from 2 well educated doctors from the likes of Harvard and Texas Children’s Hospital.
It is great you want to bless someone else. Just make sure what you give is blessing and not a hardship.
