A. Your body should tell you when it's time for a new one – but are you paying attention? If you regularly wake up feeling stiff and sore or if you aren't sleeping as well as you did a year ago, it may be time to replace what you're sleeping on. At least twice a year, check for visible signs of wear and tear and ask yourself if you're sleeping better or worse than you did a year ago and if a new mattress might improve your sleep. This regular sleep check-up will help ensure your mattress is still doing its job.
