Most Zoma customers enjoy better sleep beginning their very first night. But, in rare cases, it may take some time to adjust to your new Zoma mattress. You probably slept on your last mattress for many years – possibly even decades. During that time, your body became accustomed to the support it received. After that much time, any change to your sleeping surface — even an objectively better one — may cause some initial discomfort. That's because your body needs to adjust to the new and improved support before it feels comfortable again. Don’t worry though. If you don’t love your Zoma mattress, you’re protected by our risk-free, 100-night trial. To ensure optimal adjustment, we ask customers to trial their mattress for at least 30 nights prior to initiating a return. This allows for a thorough experience to truly decide if the mattress is right for you. Learn more on our Sleep Trial page.
