Sealy beds not living up to promises

My husband and I first bought a Sealy bed 4 years ago and in 4 years we've exchanged the bed 4 times because of the inferior quality. <br> <br> A year ago we received a different, supposedly better bed from Sealy but, from personal experience, there doesn't appear to be such a thing as a better Sealy bed! <br> <br> I now have to call Sealy to come inspect the bed that we've had for a year as it is creaking and one side of the bed has lost the support it used to provide so much so that it is giving me aches and pains when I sleep. We don't jump on the bed nor are we over-weight so the problem is with the quality of the bed itself. <br> <br> Sealy wants to \help the world sleep better"but how can this be achieved if the quality of its products is not up to scratch? Exchange number 5 is on the cards. 5 valid exchanges in 4 years is ridiculous and it is frustrating to have to keep exchanging a bed every year! Sealy is not living up to its promises and is losing its customer confidence fast!"""
