extra firm
An extra firm mattress provides the highest level of support, ideal for individuals who need maximum spinal alignment, such as back sleepers or those with back pain. This comfort level prevents the body from sinking, maintaining a flat and stable sleeping surface that promotes proper posture. Extra firm mattresses are often recommended for heavier individuals, as they resist sagging over time. They’re also a great choice for people who prefer a no-nonsense, solid feel while sleeping.
