I have head pillows purchased from the spa manufacturer (now Jacuzzi, I believe) that have developed blisters after only a year. I am careful about adding chemicals (bleach and acid) and chlorine levels are not high
1/ Can anyone shed any light as to the likely reason for the blisters?
2/ Recommendations as to where to buy good, durable replacements? Not necessarily from Sweetwater/Sundance/jacuzzi which are expensive, and obviously not long-lasting
