Worst bed I've ever had

This bed was great for the first 2 weeks or so, then it went south! There was literally a hole I laid in on my side with a hill, yes a hill in the middle. My back felt awful every day, which I finally linked to this bed after 100's of dollars in chiropractic and PT appointments. This bed is the lowest quality I've ever seen for such a big price. I don't know how they can sell a bed like this. I must say, after complaining to Sealy for 7 months, they agreed to refund my money. They now have a completely new line of beds. Maybe they realized they needed to revamp.
