Which mattresses are best for senior sleepers? The human body changes as it gets older, and senior citizens might need a different kind of bed than what they needed in their younger years. Sometimes aches and pains are just due to getting older, but it could be a mattress that is causing the problem. The biggest thing is to find one that fits you, because what is firm to one person might be too soft to another person. Seniors need to have mattresses that address issues they face, such as arthritis or aches and pains that are indeed part of getting older. Comfort is key, but seniors also need mattresses that give support to areas where it is needed. A combination of firmness in the right places, but enough softness to give comfort is a good balance to find.
