There are a few pros and cons to consider when purchasing a hard mattress. For the most part, hard mattresses are said to be more supportive and comfortable than soft ones. However, there are some potential drawbacks to consider as well. First, hard mattresses can be harder on the spine overall, potentially leading to discomfort and stiffness over time. Additionally, since they can be more isolating and difficult to move around on, people with mobility issues may find them less accommodating.
