I have a nice lather sofa, but the cushions keep falling off it when
one sits on the sofa. Virtually every 10-15 minutes, you have stand up
and pull back the cushions so they don't fall off. Are there any kind
of specially degigned velcro or any other kind of straps or adhesive
tape of some kind that one can use to keep the cushions on a leather
sofa from falling without damaging the furniture?

Would really appreciate the answer.

Thanks!
