For the ridiculous amount of money that was paid for this...

For the ridiculous amount of money that was paid for this mattress, I expected it to last for at least 10 years but I noticed that it started to sag after about 6 months. At first I thought that it was just my imagination. But after a year it was very evident that this mattress is definitely sagging. I have had a lot of hip pain. I am a side sleeper. This is the most disappointing mattress that I have ever purchased. I will never buy a Sealy product ever again.
