What's behind our mattress Ratings?

• Side sleeping
  A measure of how well a mattress supports and maintains the horizontal alignment of the spine while you're lying on your side.
• Back sleeping
  A measure of how well a mattress supports and maintains the spine's natural curve while you're lying on your back.
• Durability
  Our analysis of how well a mattress maintains its original shape, height, firmness, and side/back sleeping support after 8 years of simulated use.
