Sloppy Summer Blush

I am used to buying good quality mattresses that need replacing every 7-10 years. I've had this mattress for barely 2 years and it is already a sagging squishy mess. When you sit on the side it literally dips right down to the box spring and rolling over on it is like digging yourself out of a ditch just to fall back in. I've described it as like sleeping in pudding to friends. It makes for a horrible night's sleep and isn't even a decent enough surface to simply sit up on to read a book and if you get too close to the edge you will literally roll right out as the edges dip down so much. It's mind blowing how much this mattress is sagging and it was over $2000 regular price & about $1500 on sale. It was definitely billed as a high end mattress by the salesperson but it certainly doesn't feel like one.
