No, the mattress was designed to be ready on delivery while keeping its form and comfort for the long-term. Although the mattress doesn't have a break-in period, your body takes time to adjust to a new bed, especially if you previously slept on a spring, too soft, or too hard of a mattress. This body adjustment period could take several weeks, which is why we offer a 90 night trial period. Just like you can’t get the feel of a mattress by laying on it for 10 minutes at a store, everyone won’t get the true experience of sleeping on the Legend mattress their first night. Your muscles and back change from day to day, depending on stress, activities, and mood, so let yourself ease into the mattress to see that it is truly the best sleep experience for you.
