Welcome to our forum.
It could be the headrests themselves. If they had some kind of small hole in them, water can get into them and damage them. I'd doubt you did anything specifically to damage them. Headrests don't last a very long time.
pulling up this old post of mine about damage to the "pillows" for an update...I just found out in talking with my dealer that headrests of this type are notorious for not lasting. The tub is about 1 1/2 years old, and it happens to be a Jacuzzi 345, with two-part oval pillows. The inner part that the light shines through looks fine, but it's the outer (back) part that is softer rubber and they are all going bad. My chems have been well balanced, so I didn't think I caused it. The dealer said it's the combination of ozonator and chemicals that's causing it, and he said it's a problem with other manufacturers as well. He claims that most hot tub manufacturers are moving away from rubber pillows because of this problem. I found some replacements, but they're around $20 per I'm wondering if there are any permanent fixes for this, like a harder rubber replacement, so that I don't have to get new ones every year or two? I've searched on-line, but have only found the original parts. Any thoughts from the experts?

Any thoughts from the experts?I'd do some searching on-line before you buy any, because I found several sites that have the various headrest parts individually, so you can buy just what you need. I got several on-line prices, then talked with my local Jacuzzi dealer, who matched the lowest on-line price, and I saved shipping I have a 2003 J-370 and also had no issues until about a year and a half ago when I notice mine also starting to deteriorate. I expect that as others have pointed out that something chemically got "out of whack" over a short period and caused the sudden event (nothing for five years and the...all four in the same month). There are Jacuzzi dealers on here and I did get a price for replacement but it wasn't for only the cushion but also to replace both the mounting and the cushion itself (around $150 for the eight pieces so you are correct in that it is not cheap). I have yet to buy them as other priorities seem to be happening & my boys don't ever use the cushions as they would rather splash and play, the only person it is impacting is me and I am fine resting my head on the shell itself. I'll probably still buy the replacement parts and simply keep them in a drawer for the day I decide to sell it.
