Screaming loud on the edges

I've had many differenet mattresses in the past but I can honestly say that I've never had one like this. After 2 months the sides of the mattress made so much noise getting in and out of the bed that if I get up in the middle of the night, it wakes my husband up! It's kind of a groan, kind of a screaming sound and you can tell it's the "extra" support on the sides of the mattress. It's really disturbing. And then there are the large sink holes everyone else is writing about. It would be funny if it weren't so pathetic. Imagine yourself turning over at night and feeling like you have to climb up a hill to get to a part of the bed that has a little support. That's what you do with this mattress. Our mattress is only 6 months old. The previous mattress we had lasted 10 years and it never got this bad. So, you know you are dealing with low-class manufacturers. There is no other way to describe it. I just wish I had checked the reviews before we bought!
