We slept for more than 15 years on a firm Sealy Posturepedic mattress my in-laws bought us for a wedding present. We loved it! The only reason we got a new one 8 years ago was the first one was a full size and we wanted a queen size. We bought another Sealy Posturepedic, hoping for the same comfort and longevity. Ha! The mattress was really comfortable at first, and for about 6 years, but then developed valley-like indentations. Since it was still under warranty, we were able to replace it this past April. I made a huge mistake and got a plush. In just the 6 months since then, our new one has gotten lumps and valleys as bad as the previous one!! I can't sleep through the night and have neck and shoulder pain now.
Presently, I have no idea what to buy and am paralyzed by fear of making the same mistake. Does Sealy even make a good mattress anymore? I see you have some Simmons mattresses on your website, but am surprised since they contain memory foam. Any advice you can give is much appreciated!
