With all of the choices out there how does someone know if they are making the right decision? Memory Foam, or Air, Springs or Gel, there is no real way to test the product. Because No store offers an overnight test. Tempur-Pedic main complaint is the cost (marketing) and heat, Sleep Number looses air & has a seperation bump in the middle of the bed. Pillow tops wear and end up with a dip after a few years, and gel beds leak. I am curious to hear feedback on all of these different mattresses and the problems that come with them.
