I know what you mean. We purchased from Mathis Brothers Factory Outlet a $619 mattress and three years down the road, it was so swayed with no support whatsoever.
We tried to return it on a ten year warranty and have reached a roadblock bigger than the Empire State Building. Mathis Brothers pawns you off on the mattress maker who tries everyway imaginable to pass the buck. I will never buy anything from Mathis Brothers again. It was such a draining, upsetting experience.
I think they even switched the mattress I originally chose for another because when I laid down on it once delivered, I noticed a definite difference in the feel of the mattress which was covered at the factory because they said it voided the warranty if it was ever removed. I removed it a year later because I bought a better cover and then I could see, the mattress was a pillow top and I absolutely HATE pillow tops, would never have purchased one!!!
