Firm mattresses aren’t always better for your back. Think twice before buying a hard or ultra firm mattress. There is a difference between firm support and firm feel. You want firm support with a comfortable feel (comfortable will be defined by your personal preference). Research has shown that on average the best mattress for lower back pain is a medium firm mattress rather than an ultra firm mattress. Everyone is different, so discuss back issues with your doctor and find the right fit for your body. Any mattress that helps you sleep comfortably and wake up feeling refreshed, without pain and stiffness, is the best mattress for you. There is no single mattress that works for all people. You should choose the mattress that provides adequate support and meets your standards for comfort and allows you to get a good night’s sleep.
