Check the foundation before buying anything

A flexible or damaged base can make a mattress feel softer and less stable. Confirm the mattress maker's foundation requirements. A compatible firmer surface, cooler room, or thin firm topper may change feel slightly, but none can restore a worn-out support core.

Questions to ask before you buy

  • Does the firmness make sense for my primary sleep position and body weight?
  • Will the construction fit my preference for contouring versus responsiveness?
  • Are temperature and partner movement important enough to change the construction I choose?
  • What foundation does the manufacturer require?
  • What are the current trial, return-fee and warranty terms?
