Worst mattress to buy

I purchased a Sealy mattress 3 years ago. This has been the worst mattress I have ever purchased. I have had the mattress inspected by Sealy during the guarantee period, but they came to inspect with a preconceived decision that there was nothing wrong with the mattress. The inspector didn't even listen to what I was explaining about the mattress defects. This is the last mattress I will purchase from the company that manufactures Sealy or any of their other brands.
