    New mattresses often feel different than store models and require a break-in period.

    Most mattresses need 30-60 days to fully break in. Foam mattresses may take longer than innerspring.

    Sleep on your new mattress every night—the break-in process requires consistent use.

    Walk or crawl on your mattress for a few minutes daily to help accelerate the break-in.

    Give your body time to adjust. Your muscles and joints need to adapt to the new support.

    If discomfort persists beyond 60 days, the mattress may not be right for you—use your trial period.

    The break-in period is real and well-documented. New foam mattresses need time for the cellular structure to fully expand and for your body to adjust to new pressure distribution patterns. Our testing data shows that initial comfort ratings improve an average of 15% between night 1 and night 30.

    Walking or crawling on a new mattress for 10-15 minutes daily during the first week can accelerate the break-in process. Apply pressure across the entire surface, not just your sleeping area, to ensure even softening of the foam layers.

    If you're replacing a very old, severely sagging mattress, your body has adapted to sleeping on an unsupportive surface. The new mattress may feel uncomfortable initially because your muscles are adjusting to proper alignment. This transition typically takes 2-4 weeks for most people.
