My hot tub cover is 2 years old and the seams are coming apart. Anytime we have heavy rain my tub takes on water. I have been wiping the cover with a softener and have turned the cushions at least once in two years. I sent pictures to my dealer so that he can send it to the cover manufacturer for warranty work. The warranty is three years and states you must turn the cushions every three months. My dealer doesn’t think they will honor the warranty. Has anyone gone through this?
