The Serta Kingsport Medium is an innerspring mattress with a tight top and a medium feel. It uses three support zones aimed at the lower back, breathable fabrics and responsive coils for a traditional bouncy feel. It suits sleepers who like a classic spring mattress with some pushback rather than a sinking memory-foam hug. Against foam-heavy rivals it trades contouring for airflow and easy movement, and Serta offers upgraded versions with cooling and pressure-relief layers for hot sleepers.
