I have an Olhaussen that I am looking to recover and I am considering replacing my cushions as well. My table is over 20 years old and has the original Accufast cushions on it. I know these cushions are supposed to last a lifetime but to me it seems as if they aren't as lively as they should be. Is there a proven way to test to see if they are still up to standard. If I need to replace, then obviously when I get my table recovered is the time to do it. I just don't want to spend money unnecessarily if I don't have to.
