Sealy poor product , poor service and pathetic attitude

Bought a bran new Sealy king mattress from dial a bed. After ten day it started sagging. Reported it to dail a bed. They were efficient and had Sealy inspector visit. He said it was normal a we should read the warranty 😡. Well now after a couple of months it is no better, you either sleep in the valley or on the hill 😂😢. That’s if one can get any sleep at all. Reported again to dial a bed and they claimed that Sealy would send another inspector out. That is now over a month ago and NOTHING. It appears Sealy couldn’t care less about their X customers.
