Thanks for sharing. We are having other issues with our 13 year old set. I was getting the run-around from the head office and decided to see if others had issues.
Because of your post, I took ours apart today and found the beginning of mold on the air chambers. The foam is gray so it doesn't show but must be there too. This discovery answers some questions about sinus and breathing problems we are experiencing. We removed the bed from the house tonight.
No one offered to replace the airchambers or foam even though both were the problems I inquired about (air chamber losing air and foam disintegrating).
Has your problem been resolved yet? Care to share?
