firm mattress
Stiff sleeping surface
A firm mattress is one that offers substantial resistance and minimal give when you lie on it, as opposed to a soft or plush mattress that conforms more to the body.
Firmness exists on a spectrum, and what manufacturers call "firm" varies considerably.
People with back pain often prefer firm mattresses for support, though the ideal firmness depends on sleeping position and personal preference.
